I. MEANING OF GEOGRAPHY
 Greek word, geographia, "earth
description“
 A science that deals with the description,
distribution, and interaction of the diverse
physical, biological, and cultural features
of the earth’s surface.
 A delineation, or systematic arrangement
of constituent elements.
II. THE CONCEPT OF GEOGRAPHY
Geography identifies the
concepts of place, space
environment, interconnection,
sustainability, scale and change as
integral to the development of
geographical understanding.
PLACE
Geography, understanding of the concepts of
place is developed on the following ways:
1. Places are parts if the Earth’ surface that are
identified and given meaning by people. They
perceived, experienced, understood and
valued differently.
2. Places are important to our security, identity,
and sense of belonging, they provide us with
the services and facilities needed to support
and enhance our lives.
3. The environmental characteristics of a place
are influenced by human actions and the
actions of environmental processes over
short to long time period.
4. The human characteristics of a place are
influenced by its environmental
characteristics and resources, relative
location, connections with other places, the
culture of its population the economy of a
country, and the decisions and actions of
people and organizations over time at
5. The places in which we live are created,
changed and managed by people.
6. Each place is unique in its characteristics.
As a consequence, the outcomes of similar
environmental and socioeconomic
processes vary in different places, and
similar problems may require different
strategies in different places.
7. The sustainability of places may be
threatened by a range of factors.
SPACE
The concept of space is about the
significance of location and spatial distribution,
and ways people organize and manage the
spaces that we live in. In Australian Curriculum:
Geography, an understanding of the concept of
space is developed in the following ways:
a. The environmental and human characteristics
of places are influences by their location and
distance from other places on people are being
reduced, though unequally, by improvements in
transport and communication technologies.
b. The individual characteristics of places form
spatial distributions and the analysis of
these distributions contributes to
geographical understanding.
c. Spaces are perceived, structured, organized
and managed by people and can be
designed and redesigned, to achieve
particular purposes.
ENVIRONMENT
The concept of environment is about the
significance of the environment in human life,
and the important interrelationships between
humans and the environment. In Australian
Curriculum: Geography, an understanding of
the concept of environment is developed in
the following ways:
1. the environment is the product of geological,
atmospheric, hydrological, geomorphic,
edaphic (soil), biotic and human processes.
2. The environment supports and enriches
human and other life by providing raw
materials and food, absorbing and recycling
wastes, maintaining a safe habitat and
being a source of enjoyment and inspiration.
3. Culture, population density, type of
economy, level of technology, values and
environmental worldviews influence the
different ways in which people perceive,
adapt to use similar environment.
4. Management of human-induced
environmental change requires an
understanding of the causes and
consequences of change, and involves the
application of geographical concepts and
techniques to identify appropriate strategies.
5. Each type of environment has its specific
hazards. The impact of these hazards on
people is determined by both natural and
human factors, and can be managed but not
eliminated by prevention, mitigation and
preparedness.
INTERCONNECTION
The concept of interconnection emphasizes
that no object of geographical study can be
viewed in isolation. In Australian Curriculum:
Geography, an understanding of the concept of
interconnection is developed in the following
ways:
1. Places, people and organizations in places are
interconnected with other places in a variety of
ways. These interconnections have significant
influences on the characteristics of places and
on changes in these characteristics.
2. Environmental and human processes, for
example, the water cycle, urbanization or
human-induced environmental change, are
sets of cause-and-effect interconnections
that can operate between and within places.
They can sometimes be organized as
systems involving networks of
interconnections through flows of matter,
energy, information and actions.
3. Holistic thinking is about seeing the
interconnections between phenomena and
processes within and between places.
SUSTAINABILITY
The concept of sustainability is about the
capacity of the environment to continue to
support our lives and the lives of other living
creatures into the future. In Australian
Curriculum: Geography, an understanding of the
concept of sustainability may be developed in the
following ways:
a. Sustainability is both a goal and a way of
thinking about how to progress towards that
goal.
b. Progress towards environmental sustainability
depends on the maintenance or restoration of
the environmental functions that sustain all life
c. An understanding of the causes of non
sustainability requires a study of the
environmental processes producing the
degradation of an environmental function; the
human actions that have initiated these
processes; and the attitudinal, demographic,
social, economic and political causes of these
human actions.
d. There are a variety of contested views on how
progress towards sustainability should be
achieved and these are often informed by
worldviews such as stewardship.
SCALE
The concept of scale is about the way that
geographical phenomena and problems can be
examined at different spatial levels.
1. Generalizations made and relationships found at one
level of scale may be different at a higher or lower
level. For example, in studies of vegetation, climate
is the main factor at the global scale but soil and
drainage may be the main factors at the local scale.
2. Cause-and-effect relationships cross scales from the
local to the global and from the global to the local.
For example, local events can have global
outcomes, such as the effects of local vegetation
removal on global climate.
CHANGE
The concept of change is about explaining
geographical phenomena by investigating how they have
developed over time. In Australian Curriculum: Geography,
an understanding of the concept of change may be
developed in the following ways:
1. Environmental change can occur over both short and
long-term time frames, and both time scales have
interrelationships with human activities.
2. Environmental, economic, social and technological
change is spatially uneven, and affects places differently.
3. An understanding of the current processes of change can
be used to predict change in the future and to identify
what would be needed to achieve preferred and more
sustainable futures.
HISTORY OF GEOGRAPHIC STUDY
Evolution
Geography was first systematically studied by the
ancient Greeks, who also developed a philosophy of
geography; Thales of
Miletus, Herodotus, Eratothenes, Aristotle, Strabo,
and Ptolemy made major contributions to geography.
The Roman contribution to geography was in the
exploration and mapping of previously unknown lands.
Greek geographic learning was maintained and
enhanced by the Arabs during the middle Ages. Arab
geographers, among whom Idrisi, Ibn Battutah, and Ibn
Khaldun are prominent, traveled extensively for the
purpose of increasing their knowledge of the world.
The journeys of Marco Polo in the latter part of the
Middle Ages began the revival of geographic interest
outside the Muslim world.
With the Renaissance in Europe came the
desire to explore unknown parts of the world that
led to the voyages of exploration and to the great
discoveries. However, it was mercantile interest
rather than a genuine search for knowledge that
spurred these endeavors. The 16th and 17th
century. Reintroduced sound theoretical
geography in the form of textbooks
(the Geographia generalis of Bernhardus Varenus)
and maps (Gerardus Mecator's world map). In the
18th cent. geography began to achieve recognition
as a discipline and was taught for the first time at
the university level.
Modern Geography
The modern period of geography began
toward the end of the 18th cent. with the works
of Alexander von Humboldt and Karl Ritter.
Thenceforth two principal methods of approach
to geography can be distinguished: the
systematic, following Humboldt, and the
regional, following Ritter. Of the national
schools of geography that developed, the
German and the French schools were the most
influential.
 The German school, which dealt mainly with
physical geography, developed a scientific
and analytical style of writing. The French
school became known for its descriptive
regional monographs presented in a lucid
and flowing manner; human and historical
geography were its forte. Although emphasis
has shifted several times between the
approaches and viewpoints, their
interdependence is recognized by all
geographers.
Nature of Geography
Geography is concerned with place. Understanding
the nature and causes of areal differentiation on the
global surface has been the geographer’s task since
people first noticed differences between places.
First, geography is strongly influenced by the
norms of the social sciences. The complexity and
changing nature of human society seldom permit the
type of precision expected in the physical sciences.
Instead, the social sciences offer a variety of
perspectives and methods of study by which to
examine the consequences of human behavior on the
global surface
Second, physical geographers, no less than
human geographers, contribute to an
understanding of place; for the concept of site --
the physical characteristics of a place -- is integral
to understanding areal differentiation on the global
surface.
The view of geography presented here is that
of a core sharply focused on the concept of place;
one in which both physical and human elements
play an important part in yielding knowledge of the
earth in a manner that is integrative of people and
the land.
ELEMENTS OF GEOGRAPHY
1. The World in Spatial Terms
a. How to use maps and other geographic
representations, tools, and technologies to acquire,
process, and report information from a spatial perspective
b. How to use mental maps to organize information about
people, places, and environments in a spatial context
c. How to analyze the spatial organization of people,
places, and environments on earth's surface
2. Places and Regions
a. The physical and human characteristics of places
b. That people create regions to interpret earth's
complexity
c. How culture and experience influence people's
perceptions of places and regions
3. Physical Systems
a. The physical processes that shape the patterns of earth's
surface
b. The characteristics and spatial distribution of ecosystems
on earth's surface
4. Human Systems
a. The characteristics, distribution, and migration of human
populations on earth's surface
b. The characteristics, distribution, and complexity of earth's
cultural mosaics
c. The patterns and networks of economic interdependence
on earth's surface
d. The processes, patterns, and functions of human
settlement
e. How the forces of cooperation and conflict among people
5. Environment and Society
a. How human actions modify the physical
environment
b. How physical systems affect human systems
c. The changes that occur in the meaning, use,
distribution, and importance of resources
6. The Uses of Geography
a. How to apply geography to interpret the past
b. How to apply geography to interpret the present
and plan for the future
IMPORTANCE OF GEOGRAPHY
 Geography provokes and answers questions
about the natural and human worlds, using
different scales of enquiry to view them from
different perspectives.
 It develops knowledge of places and
environments throughout the world, an
understanding of maps, and a range of
investigative and problem solving skills both
inside and outside the classroom. As such, it
prepares pupils for adult life and employment.
 Geography is a focus within the curriculum for
understanding and resolving issues about
environment and sustainable development.
 It also an important link between the natural and
social sciences. As pupils study geography, they
encounter different societies and cultures.
 This helps them realize how nations rely on each
other.
 It can inspire them to think about their own place
in the world, values and their rights and
responsibilities to other people and the
THE RELATIONSHIP OF GEOGRAPHY TO OTHER
SOCIAL SCIENCE DISCIPLINES
This revived interest in places is a feature of
the third contemporary strand, with geographers
participating in the growing field of cultural studies
that encompasses scholars from the humanities
and social sciences in new ways of studying
human action in context. Such work ranges over
many aspects of behavior, including the micro-
scale of the individual body, seeking to
understand the meanings that underpin actions –
many of which are never recorded during the
processes of everyday life –and how communities
and groups identify with places and spaces.
The relationships between people and
nature are also being reconsidered, breaking
down the perceived artificial boundaries
between these long-considered opposites.
New approaches for interrogating actions are
being explored: geography quite literally
studies where events ‘take place’ and the
impact of those events is reflected in the
places’ character. Indeed, such is the
geographical contribution to cultural studies
that some identify a ‘spatial turn’ within the
humanities.
PHYSICAL GEOGRAPHY
The natural environment is the primary
concern of physical geographers, although
many physical geographers also look at how
humans have altered natural systems.
Physical geographers study Earth’s
seasons, climate, atmosphere, soil, streams,
landforms, and oceans. Some disciplines
within physical geography include
geomorphology, glaciology, pedology, hydrolog
y, climatology, biogeography,
and oceanography.
Geomorphology is the study of landforms
and the processes that shape them.
Geomorphologists investigate the nature and
impact of wind, ice, rivers, erosion,
earthquakes, volcanoes, living things, and other
forces that shape and change the surface of the
Earth.
Glaciologists focus on the Earth’s ice fields
and their impact on the planet’s climate.
Glaciologists document the properties and
distribution of glaciers and icebergs. Data
collected by glaciologists has demonstrated the
retreat of Arctic and Antarctic ice in the past
Pedologists study soil and how it is created,
changed, and classified. Soil studies are used by a
variety of professions, from farmers analyzing
field fertility to engineers investigating the suitability of
different areas for building heavy structures.
Hydrology is the study of Earth’s water: its
properties, distribution, and effects. Hydrologists are
especially concerned with the movement of water as it
cycles from the ocean to the atmosphere, then back to
Earth’s surface. Hydrologists study the water
cycle through rainfall into streams, lakes, the soil, and
underground aquifers. Hydrologists provide insights that
are critical to building or removing dams,
designing irrigation systems, monitoring water quality,
tracking drought conditions, and predicting flood risk.
Climatologists study Earth’s climate system and
its impact on Earth’s surface. For example,
climatologists make predictions about El Nino, a
cyclical weather phenomenon of warm
surface temperatures in the Pacific Ocean. They
analyze the dramatic worldwide climate changes
caused by El Nino, such as flooding in Peru, drought
in Australia, and, in the United States, the oddities of
heavy Texas rains or an unseasonably warm
Minnesota winter.
Biogeography's study the impact of the
environment on the distribution of plants and animals.
For example, a biogeography might document all the
places in the world inhabited by a certain spider
species, and what those places have in common.
Oceanography, a related discipline of physical
geography, focuses on the creatures and environments
of the world’s oceans. Observation of ocean tides
and currents constituted some of the first oceanographic
investigations. For example, 18th-century mariners
figured out the geography of the Gulf Stream, a massive
current flowing like a river through the Atlantic Ocean.
The discovery and tracking of the Gulf Stream helped
communications and travel between Europe and the
Americas.
Today, oceanographers conduct research on the
impacts of water pollution, track tsunamis,
design offshore oil rigs, investigate underwater eruptions
of lava, and study all types of marine organisms
from toxic algae to friendly dolphins.
HUMAN GEOGRAPHY
Human geography is concerned with the distribution
and networks of people and cultures on Earth’s surface.
A human geographer might investigate the local,
regional, and global impact of rising economic powers
China and India, which represent 37 percent of the
world’s people. They also might look at how consumers
in China and India adjust to new technology
and markets, and how markets respond to such a huge
consumer base.
Human geographers also study how people use
and alter their environments. When, for example,
people allow their animals to overgraze a region, the
soil erodes and grassland is transformed into desert.
The impact of overgrazing on the landscape as well as
agricultural production is an area of study for human
Finally, human geographers study how political,
social, and economic systems are organized across
geographical space. These include governments,
religious organizations, and trade partnerships. The
boundaries of these groups constantly change.
The main divisions within human geography reflect
a concern with different types of human activities or
ways of living. Some examples of human geography
include urban geography, economic geography, cultural
geography, political geography, social geography, and
population geography. Human geographers who study
geographic patterns and processes in past times are
part of the sub discipline of historical geography. Those
who study how people understand maps and
geographic space belong to a sub discipline known as
Many human geographers interested in the relationship
between humans and the environment work in the sub disciplines of
cultural geography and political geography.
Cultural geographers study how the natural environment
influences the development of human culture, such as how the
climate affects the agricultural practices of a region. Political
geographers study the impact of political circumstances on
interactions between people and their environment, as well as
environmental conflicts, such as disputes over water rights.
Some human geographers focus on the connection between
human health and geography. For example, health geographers
create maps that track the location and spread of specific diseases.
They analyze the geographic disparities of health-care access. They
are very interested in the impact of the environment on human
health, especially the effects of environmental hazards such
as radiation, lead poisoning, or water pollution.

THE GLOBE
A globe is a three-dimensional,
spherical,
scale model of Earth (terrestrial
globe or geographical globe) or other
celestial body such as a planet or moon.
While models can be made of objects
with arbitrary or irregular shapes, the
term globe is used only for models of
objects that are approximately
 Latitude Lines Imaginary lines running horizontally
around the globe. Also called parallels, latitude lines
are equidistant from each other. Each degree of
latitude is about 69 miles (110 km) apart. Zero
degrees (0°) latitude is the equator, the widest
circumference of the globe. Latitude is measured
from 0° to 90° north and 0° to 90° south—90° north is
the North Pole and 90° south is the South Pole.
 Longitude Lines Imaginary lines, also called
meridians, running vertically around the globe. Unlike
latitude lines, longitude lines are not parallel.
Meridians meet at the poles and are widest apart at
the equator. Zero degrees longitude (0°) is called the
prime meridian. The degrees of longitude run 180°
east and 180° west from the prime meridian.
 Equator Zero degrees latitude. The Sun is directly overhead
the equator at noon on the two equinoxes (March and Sept.
20 or 21). The equator divides the globe into the Northern
and Southern hemispheres. The equator appears halfway
between the North and South poles, at the widest
circumference of the globe. It is 24,901.55 miles (40,075.16
km) long
 Hemisphere a half of the earth, usually as divided into
northern and southern halves by the equator, or into western
and eastern halves by an imaginary line passing through the
poles.
 Grid latitude and longitude lines form an imaginary grid over
the Earth’s surface.
 Prime Meridian Zero degrees longitude (0°).
The prime meridian runs through the Royal
Greenwich Observatory in Greenwich, England
(the location was established in 1884 by
international agreement). The prime meridian
divides the globe into the Western and Eastern
hemispheres. The Earth's time zones are
measured from the prime meridian. The time at
0° is called Universal Time (UT) or Greenwich
Mean Time (GMT). With the Greenwich
meridian as the starting point, each 15° east
and west marks a new time zone. The 24 time
zones extend east and west around the globe
for 180° to the International Date Line.
 International Date Line Located at 180°
longitude (180° E and 180° W are the same
meridian). Regions to the east of the
International Date Line are counted as being
one calendar day earlier than the regions to the
west. Although the International Date Line
generally follows the 180° meridian (most of
which lies in the Pacific Ocean), it does diverge
in places. Since 180° runs through several
countries, it would divide those countries not
simply into two different time zones, but into two
different calendar days.
 Tropic of Cancer A line of latitude located at 23°30' north of
the equator. The Sun is directly overhead the Tropic of
Cancer on the summer solstice in the Northern Hemisphere
(June 20 or 21). It marks the northernmost point of the
tropics, which falls between the Tropic of Cancer and the
Tropic of Capricorn.
 Tropic of Capricorn A line of latitude located at 23°30'
south. The Sun is directly overhead the Tropic of Capricorn
on the summer solstice in the Southern Hemisphere (Dec.
20 or 21). It marks the southernmost point of the tropics.
 Arctic Circle A line of latitude located at 66°30' north,
delineating the Northern Frigid Zone of the Earth.
 Antarctic Circle A line of latitude
located at 66°30' south, delineating the
Southern Frigid Zone of the Earth.
 Globe The most accurate map of the
Earth, duplicating its spherical shape
and relative size.
MAPS
 Map Representation of a physical plane with
selective information. Maps represent a
definite area and contain detailed
geographical information.
TYPES OF MAPS
 Political Map: A political map does not show any
topographic features. It instead focuses solely on
the state and national boundaries of a place. They
also include the locations of cities - both large and
small, depending on the detail of the map.
Physical Map: A physical map is one that shows
the physical landscape features of a place. They
generally show things like mountains, rivers and
lakes and water is always shown with blue.
Mountains and elevation changes are usually
shown with different colors and shades to show
relief. Normally on physical maps green shows
lower elevations while browns show high
elevations.
 Topographic Map: A topographic map is similar to
a physical map in that it shows different physical
landscape features. They are different however
because they use contour lines instead of colors to
show changes in the landscape.
 Climate Map: A climate map shows information
about the climate of an area. They can show things
like the specific climatic zones of an area based on
the temperature, the amount of snow an area
receives or average number of cloudy days.
 Economic or Resource Map: An economic or
resource map shows the specific type of economic
activity or natural resources present in an area
through the use of different symbols or colors
depending on what is being shown on the map.
 Road Map: A road map is one of the most widely
used map types. These maps show major and
minor highways and roads (depending on detail) as
well as things like airports, city locations and points
of interest like parks, campgrounds and
monuments.
 Thematic Map: A thematic map is a map that
focuses on a particular theme or special topic and
they are different from the six aforementioned
general reference maps because they do not just
show natural features like rivers, cities, political
subdivisions, elevation and highways.
USES OF MAPS
CLASSIFICATION OF MAPS
 REFERENCE OR NAVIGATIONAL MAPS
are created to help you navigate over the earth
surface. These kinds of maps show you where
particular places are located and can be used to
navigate you way to them. A street map or the
common highway road map falls into this category.
Physical geographers use topographic maps to
show the locations of landscape features on the
earth.
CLASSIFICATION OF MAPS
 TOPOGRAPHIC MAPS illustrate the
horizontal and vertical positions (relief) of
land surface features. Topographic maps use
contour lines to show elevation (height above
sea level).
 THEMATIC MAPS are used to communicate
geographic concepts like the distribution of
densities, spatial relationships, magnitudes,
movements etc. World climate or soils maps
are notable examples of thematic maps.
MAP ESSENTIALS
TITLE
Shows what the subject of the map is.
COMPASS ROSE
It has arrows which point in all 4 principal
directions.
SCALE
Used to represent distances between two
points on a map.
BAR SCALE

or kilometers using bars.
LEGEND
Used to explain what the symbol on a map
represents.
KEY
Another name for a legend on a map.
LOCATOR MAP

is located.
PRINCIPAL DIRECTIONS
The four directions found with a compass - North, South,
East, and West.
CARDINAL DIRECTIONS
Another name for the principal directions.
POLITICAL MAPS
Maps which show the major political features of a region.
POLITICAL FEATURES
They include country borders, capital cities and other
features.
CAPITAL CITIES
They are shown as a star on a map.
PHYSICAL MAPS
Maps which show the major physical feature of a region.
PHYSICAL FEATURES
They include mountains ranges, rivers, oceans,
islands, deserts and plains.
SPECIAL PURPOSE MAPS
Maps which focus on one special topic like
climate, resources or population.
LINE SCALE
A scale an a map which gives distances in miles
or kilometers using lines.
MAP PROJECTION
 Cylindrical: In standard presentation, these
map regularly-spaced meridians to equally
spaced vertical lines, and parallels to
horizontal lines.
 Pseudocylindrical: In standard
presentation, these map the central meridian
and parallels as straight lines. Other
meridians are curves (or possibly straight
from pole to equator), regularly spaced along
parallels.
 Pseudoazimuthal: In standard presentation,
pseudoazimuthal projections map the equator and
central meridian to perpendicular, intersecting straight
lines. They map parallels to complex curves bowing
away from the equator, and meridians to complex
curves bowing in toward the central meridian. Listed
here after pseudocylindrical as generally similar to
them in shape and purpose.
 Conic: In standard presentation, conic (or conical)
projections map meridians as straight lines, and
parallels as arcs of circles.
 Pseudoconical: In standard presentation,
pseudoconical projections represent the central
meridian as a straight line, other meridians as
complex curves, and parallels as circular arcs.
 Azimuthal: In standard presentation, azimuthal
projections map meridians as straight lines and
parallels as complete, concentric circles. They are
radially symmetrical. In any presentation (or
aspect), they preserve directions from the center
point. This means great circles through the central
point are represented by straight lines on the map.
 Other: Typically calculated from formula, and
not based on a particular projection
 Polyhedral maps: Polyhedral maps can be
folded up into a polyhedral approximation to the
sphere, using particular projection to map each
face with low distortion.
 Retroazimuthal: Direction to a fixed location B
(by the shortest route) corresponds to the
direction on the map from A to B.

FLORA AND FAUNA
 Fauna derives from the name of a Roman goddess,
but the handiest way to remember flora
and fauna is that "flora" sounds like flowers, which
are part of the plant world, and fauna sounds like
"fawn," and fawns are part of the animal kingdom.
 Flora and fauna refer to plant and wildlife,
respectively. The term is often used to refer
to the indigenous plant and wildlife of a
geographical region. Both are collective
terms, referring to groups of plant or wildlife
specific to a region or a time period. For
example, the flora and fauna of a warm
region may consist of tropical to warm-
temperate vegetation and exotic species of
birds.
 By definition, flora is a word of Latin origin
referring to Flora, the goddess of flowers. The
term can refer to a group of plants or to
bacteria. Flora is the root of the word floral,
which means pertaining to flowers. Fauna can
refer to the animal life or classification of
animals of a certain region, time period, or
environment. The term is also of Latin origin,
and in Roman mythology, Fauna was the sister
of Faunus, a good spirit of the forest and plains.
 The flora and fauna of any given region are
usually explained in biological terms to
include the genus and species of plant and
animal life, their preferred growing or
breeding habits, and their connection to one
another in the environment as well. In
addition to geographical groupings,
environment also helps further their
classification. For example, aquatic flora and
fauna of a region refers to the plant and
animal life found in the waters in or
surrounding a geographic region.
THE IMPORTANCE OF FLORA AND FAUNA TO
HUMAN EXISTENCE ON EARTH
 Flowers and animals; we can't live without
them. The flora of the earth produce the
oxygen that is breathed by the fauna and in
turn, the fauna exhale the carbon dioxide that
the flora need to live. One cannot live without
the other, and humans cannot live without
either; hence their importance.
 Flora and fauna are the plant and animal life
of a region in a period of time. That may
sound simple, but the ecosystem created by
the interdependence of these two life forms
is not simple at all. In fact, humans cannot
breathe unless both flora and fauna survive
and thrive on the earth.
 The very air we breathe and the food we eat,
the medicines that cure us, and the water that
keeps us alive would not exist were it not for
flora and fauna. All things in an ecosystem are
interdependent. The existence of one species
may depend on the health of another, such as
the relationship of bamboo forests to pandas.
Pandas only eat bamboo shoots, so the
destruction of the bamboo forests in China
resulted in the endangerment of the Panda,
due to starvation and loss of habitat.
 In China, destruction of the forests left the
tigers with no place to go. Farmers killed
them in great numbers to protect their farm
animals, and soon there were few left. In an
attempt to save the species, Chinese tigers
were moved to the forests of Africa, where
they are surviving nicely.
ENDANGERMENT OF OCEAN FLORA AND FAUNA
 The importance of flora and fauna in the
oceans cannot be underestimated, many of
which are endangered or extinct due to
pollution and other of man's actions.
 Excessive dumping of nitrogen rich fertilizers
into the Gulf of Mexico has created the
growth of huge colonies of red algae, called
"red tide", which kills millions of ocean
creatures every year, and even a few
hypersensitive humans.
 The mass killing of sharks has created a
dangerous overpopulation of sting rays.
Overfishing and whaling in Japan has caused
many species of whales to be seriously
endangered.
 The Great Barrier Reef, home to millions of
the ocean's species, is dying due to pollution
and rising water temperatures, which is
causing a ripple effect unlike any we will ever
again see.
GLOBAL EFFECTS OF THE DESTRUCTION OF
FLORA AND FAUNA
 The importance of flora and fauna cannot be
seen anywhere as distinctly as in our
rainforests. The Amazon rainforest once
gave us 20% of our oxygen supply. As their
destruction has progressed, so has the
incidence of respiratory illness around the
world. Some of our most effective drugs
come from rainforest plants. Destruction of
these plants, and their habitats, will not only
affect our health, but our very lives.
 Half of the world's species of plants, animals
and microorganisms have become
endangered or extinct due to this pernicious
destruction of the rainforest. Birds and
animals are in part responsible for keeping
the rainforest alive, by spreading seeds
through their feces. Without them, many
plant species cannot propagate, and will
disappear.
MAN'S DESTRUCTION OF ECOSYSTEMS
 Man, in his quest for money and power, has created a
world in which the ecological balance of flora and
fauna has been destroyed, in many instances
causing the extinction of entire species due to
destruction of habitat and food sources.
 Manmade "acid rain" killed entire forests when it blew
into Canada and fell on the trees there. Smog has
killed plants, animals and even humans. The hole in
the ozone, said to be the main cause of the melting
arctic ice caps, is (like acid rain) believed to be
caused by the foul emissions of coal burning
factories.
GLOBAL ACTIONS CAUSE LOCAL
CONSÉQUENCES
The world's ecology is so complex, so fragile, so
interdependent, that an ecological upheaval of the
flora and fauna of one region of the world (i.e. the
destruction of rainforests) can affect the entire planet.
Global trade has introduced species to areas
outside of their natural habitat, where there are no
predatory species to control their destructive habits.
Fire ants were brought to the United States in a
cargo ship. They have caused the death of livestock,
people, and many native species of ants and insects.
You need look no further than Florida to see the
importance of native flora and fauna on the local
ecosystems.
Plants like Kudzu, Brazilian Pepper, Australian
Pine, and Chinese Tallow were brought in from other
countries to the United States and have invaded and
destroyed entire habitats of native flora. The
Everglades is being destroyed by Malaleuca, which
was seeded by airplanes to dry up the Everglades
and allow sugar cane to be planted after the Cuban
embargo.
The introduction of non-native brown anoles and
Cuban tree frogs into Florida has nearly caused the
extinction of native lizard and toad species, which
are their prey. Iguanas and other large lizard species,
as well as large snakes such as boas and pythons,
are invading the Everglades and other ecologically
sensitive areas.
In fact, Florida and its port cities have
introduced and become invaded by more
invasive non-native species than any other state
in the U.S.
Imports of salmon eggs into Japan have
caused outbreaks of disease into several of
their native fish species, causing great
economic and ecological losses.
The list goes on indefinitely. The University
of Arizona site tells a shocking tale of the
ecological and economic cost of invasive flora
and fauna to the U.S. alone every year.
WHAT CAN BE DONE?
The situation simply is out of control, and
although many organizations such as
Greenpeace and the World Wildlife Fund, as
well as local societies and agencies worldwide
are trying, there may be no solution.
The indigenous flora and fauna of the world
are dying, and the ecosystem as we know it is
dying with them. It has been said, that if insects
decided to take over the world, we would all be
doomed. If things keep going the way they are,
they may just have their chance.
 Locally, you can find organizations that are
working to teach the importance of flora and
fauna native to your area and volunteer or
donate money. Globally, you can join
organizations like the World Wildlife Fund
and support their worldwide mission to save
the flora and fauna that support the world's
ecological systems.

Geography

  • 1. LECTURE 1 MAJOR 3 (BASIC GEOGRAPHY) SUBMITTED TO: MR. SAMUEL GRECALDA SUBMITTED BY: BEED IIA-GENERAL EDUCATION
  • 2. I. MEANING OF GEOGRAPHY  Greek word, geographia, "earth description“  A science that deals with the description, distribution, and interaction of the diverse physical, biological, and cultural features of the earth’s surface.  A delineation, or systematic arrangement of constituent elements.
  • 3. II. THE CONCEPT OF GEOGRAPHY Geography identifies the concepts of place, space environment, interconnection, sustainability, scale and change as integral to the development of geographical understanding.
  • 4. PLACE Geography, understanding of the concepts of place is developed on the following ways: 1. Places are parts if the Earth’ surface that are identified and given meaning by people. They perceived, experienced, understood and valued differently. 2. Places are important to our security, identity, and sense of belonging, they provide us with the services and facilities needed to support and enhance our lives.
  • 5. 3. The environmental characteristics of a place are influenced by human actions and the actions of environmental processes over short to long time period. 4. The human characteristics of a place are influenced by its environmental characteristics and resources, relative location, connections with other places, the culture of its population the economy of a country, and the decisions and actions of people and organizations over time at
  • 6. 5. The places in which we live are created, changed and managed by people. 6. Each place is unique in its characteristics. As a consequence, the outcomes of similar environmental and socioeconomic processes vary in different places, and similar problems may require different strategies in different places. 7. The sustainability of places may be threatened by a range of factors.
  • 7. SPACE The concept of space is about the significance of location and spatial distribution, and ways people organize and manage the spaces that we live in. In Australian Curriculum: Geography, an understanding of the concept of space is developed in the following ways: a. The environmental and human characteristics of places are influences by their location and distance from other places on people are being reduced, though unequally, by improvements in transport and communication technologies.
  • 8. b. The individual characteristics of places form spatial distributions and the analysis of these distributions contributes to geographical understanding. c. Spaces are perceived, structured, organized and managed by people and can be designed and redesigned, to achieve particular purposes.
  • 9. ENVIRONMENT The concept of environment is about the significance of the environment in human life, and the important interrelationships between humans and the environment. In Australian Curriculum: Geography, an understanding of the concept of environment is developed in the following ways: 1. the environment is the product of geological, atmospheric, hydrological, geomorphic, edaphic (soil), biotic and human processes.
  • 10. 2. The environment supports and enriches human and other life by providing raw materials and food, absorbing and recycling wastes, maintaining a safe habitat and being a source of enjoyment and inspiration. 3. Culture, population density, type of economy, level of technology, values and environmental worldviews influence the different ways in which people perceive, adapt to use similar environment.
  • 11. 4. Management of human-induced environmental change requires an understanding of the causes and consequences of change, and involves the application of geographical concepts and techniques to identify appropriate strategies. 5. Each type of environment has its specific hazards. The impact of these hazards on people is determined by both natural and human factors, and can be managed but not eliminated by prevention, mitigation and preparedness.
  • 12. INTERCONNECTION The concept of interconnection emphasizes that no object of geographical study can be viewed in isolation. In Australian Curriculum: Geography, an understanding of the concept of interconnection is developed in the following ways: 1. Places, people and organizations in places are interconnected with other places in a variety of ways. These interconnections have significant influences on the characteristics of places and on changes in these characteristics.
  • 13. 2. Environmental and human processes, for example, the water cycle, urbanization or human-induced environmental change, are sets of cause-and-effect interconnections that can operate between and within places. They can sometimes be organized as systems involving networks of interconnections through flows of matter, energy, information and actions. 3. Holistic thinking is about seeing the interconnections between phenomena and processes within and between places.
  • 14. SUSTAINABILITY The concept of sustainability is about the capacity of the environment to continue to support our lives and the lives of other living creatures into the future. In Australian Curriculum: Geography, an understanding of the concept of sustainability may be developed in the following ways: a. Sustainability is both a goal and a way of thinking about how to progress towards that goal. b. Progress towards environmental sustainability depends on the maintenance or restoration of the environmental functions that sustain all life
  • 15. c. An understanding of the causes of non sustainability requires a study of the environmental processes producing the degradation of an environmental function; the human actions that have initiated these processes; and the attitudinal, demographic, social, economic and political causes of these human actions. d. There are a variety of contested views on how progress towards sustainability should be achieved and these are often informed by worldviews such as stewardship.
  • 16. SCALE The concept of scale is about the way that geographical phenomena and problems can be examined at different spatial levels. 1. Generalizations made and relationships found at one level of scale may be different at a higher or lower level. For example, in studies of vegetation, climate is the main factor at the global scale but soil and drainage may be the main factors at the local scale. 2. Cause-and-effect relationships cross scales from the local to the global and from the global to the local. For example, local events can have global outcomes, such as the effects of local vegetation removal on global climate.
  • 17. CHANGE The concept of change is about explaining geographical phenomena by investigating how they have developed over time. In Australian Curriculum: Geography, an understanding of the concept of change may be developed in the following ways: 1. Environmental change can occur over both short and long-term time frames, and both time scales have interrelationships with human activities. 2. Environmental, economic, social and technological change is spatially uneven, and affects places differently. 3. An understanding of the current processes of change can be used to predict change in the future and to identify what would be needed to achieve preferred and more sustainable futures.
  • 18. HISTORY OF GEOGRAPHIC STUDY Evolution Geography was first systematically studied by the ancient Greeks, who also developed a philosophy of geography; Thales of Miletus, Herodotus, Eratothenes, Aristotle, Strabo, and Ptolemy made major contributions to geography. The Roman contribution to geography was in the exploration and mapping of previously unknown lands. Greek geographic learning was maintained and enhanced by the Arabs during the middle Ages. Arab geographers, among whom Idrisi, Ibn Battutah, and Ibn Khaldun are prominent, traveled extensively for the purpose of increasing their knowledge of the world. The journeys of Marco Polo in the latter part of the Middle Ages began the revival of geographic interest outside the Muslim world.
  • 19. With the Renaissance in Europe came the desire to explore unknown parts of the world that led to the voyages of exploration and to the great discoveries. However, it was mercantile interest rather than a genuine search for knowledge that spurred these endeavors. The 16th and 17th century. Reintroduced sound theoretical geography in the form of textbooks (the Geographia generalis of Bernhardus Varenus) and maps (Gerardus Mecator's world map). In the 18th cent. geography began to achieve recognition as a discipline and was taught for the first time at the university level.
  • 20. Modern Geography The modern period of geography began toward the end of the 18th cent. with the works of Alexander von Humboldt and Karl Ritter. Thenceforth two principal methods of approach to geography can be distinguished: the systematic, following Humboldt, and the regional, following Ritter. Of the national schools of geography that developed, the German and the French schools were the most influential.
  • 21.  The German school, which dealt mainly with physical geography, developed a scientific and analytical style of writing. The French school became known for its descriptive regional monographs presented in a lucid and flowing manner; human and historical geography were its forte. Although emphasis has shifted several times between the approaches and viewpoints, their interdependence is recognized by all geographers.
  • 22. Nature of Geography Geography is concerned with place. Understanding the nature and causes of areal differentiation on the global surface has been the geographer’s task since people first noticed differences between places. First, geography is strongly influenced by the norms of the social sciences. The complexity and changing nature of human society seldom permit the type of precision expected in the physical sciences. Instead, the social sciences offer a variety of perspectives and methods of study by which to examine the consequences of human behavior on the global surface
  • 23. Second, physical geographers, no less than human geographers, contribute to an understanding of place; for the concept of site -- the physical characteristics of a place -- is integral to understanding areal differentiation on the global surface. The view of geography presented here is that of a core sharply focused on the concept of place; one in which both physical and human elements play an important part in yielding knowledge of the earth in a manner that is integrative of people and the land.
  • 24. ELEMENTS OF GEOGRAPHY 1. The World in Spatial Terms a. How to use maps and other geographic representations, tools, and technologies to acquire, process, and report information from a spatial perspective b. How to use mental maps to organize information about people, places, and environments in a spatial context c. How to analyze the spatial organization of people, places, and environments on earth's surface 2. Places and Regions a. The physical and human characteristics of places b. That people create regions to interpret earth's complexity c. How culture and experience influence people's perceptions of places and regions
  • 25. 3. Physical Systems a. The physical processes that shape the patterns of earth's surface b. The characteristics and spatial distribution of ecosystems on earth's surface 4. Human Systems a. The characteristics, distribution, and migration of human populations on earth's surface b. The characteristics, distribution, and complexity of earth's cultural mosaics c. The patterns and networks of economic interdependence on earth's surface d. The processes, patterns, and functions of human settlement e. How the forces of cooperation and conflict among people
  • 26. 5. Environment and Society a. How human actions modify the physical environment b. How physical systems affect human systems c. The changes that occur in the meaning, use, distribution, and importance of resources 6. The Uses of Geography a. How to apply geography to interpret the past b. How to apply geography to interpret the present and plan for the future
  • 27. IMPORTANCE OF GEOGRAPHY  Geography provokes and answers questions about the natural and human worlds, using different scales of enquiry to view them from different perspectives.  It develops knowledge of places and environments throughout the world, an understanding of maps, and a range of investigative and problem solving skills both inside and outside the classroom. As such, it prepares pupils for adult life and employment.
  • 28.  Geography is a focus within the curriculum for understanding and resolving issues about environment and sustainable development.  It also an important link between the natural and social sciences. As pupils study geography, they encounter different societies and cultures.  This helps them realize how nations rely on each other.  It can inspire them to think about their own place in the world, values and their rights and responsibilities to other people and the
  • 29. THE RELATIONSHIP OF GEOGRAPHY TO OTHER SOCIAL SCIENCE DISCIPLINES This revived interest in places is a feature of the third contemporary strand, with geographers participating in the growing field of cultural studies that encompasses scholars from the humanities and social sciences in new ways of studying human action in context. Such work ranges over many aspects of behavior, including the micro- scale of the individual body, seeking to understand the meanings that underpin actions – many of which are never recorded during the processes of everyday life –and how communities and groups identify with places and spaces.
  • 30. The relationships between people and nature are also being reconsidered, breaking down the perceived artificial boundaries between these long-considered opposites. New approaches for interrogating actions are being explored: geography quite literally studies where events ‘take place’ and the impact of those events is reflected in the places’ character. Indeed, such is the geographical contribution to cultural studies that some identify a ‘spatial turn’ within the humanities.
  • 31. PHYSICAL GEOGRAPHY The natural environment is the primary concern of physical geographers, although many physical geographers also look at how humans have altered natural systems. Physical geographers study Earth’s seasons, climate, atmosphere, soil, streams, landforms, and oceans. Some disciplines within physical geography include geomorphology, glaciology, pedology, hydrolog y, climatology, biogeography, and oceanography.
  • 32. Geomorphology is the study of landforms and the processes that shape them. Geomorphologists investigate the nature and impact of wind, ice, rivers, erosion, earthquakes, volcanoes, living things, and other forces that shape and change the surface of the Earth. Glaciologists focus on the Earth’s ice fields and their impact on the planet’s climate. Glaciologists document the properties and distribution of glaciers and icebergs. Data collected by glaciologists has demonstrated the retreat of Arctic and Antarctic ice in the past
  • 33. Pedologists study soil and how it is created, changed, and classified. Soil studies are used by a variety of professions, from farmers analyzing field fertility to engineers investigating the suitability of different areas for building heavy structures. Hydrology is the study of Earth’s water: its properties, distribution, and effects. Hydrologists are especially concerned with the movement of water as it cycles from the ocean to the atmosphere, then back to Earth’s surface. Hydrologists study the water cycle through rainfall into streams, lakes, the soil, and underground aquifers. Hydrologists provide insights that are critical to building or removing dams, designing irrigation systems, monitoring water quality, tracking drought conditions, and predicting flood risk.
  • 34. Climatologists study Earth’s climate system and its impact on Earth’s surface. For example, climatologists make predictions about El Nino, a cyclical weather phenomenon of warm surface temperatures in the Pacific Ocean. They analyze the dramatic worldwide climate changes caused by El Nino, such as flooding in Peru, drought in Australia, and, in the United States, the oddities of heavy Texas rains or an unseasonably warm Minnesota winter. Biogeography's study the impact of the environment on the distribution of plants and animals. For example, a biogeography might document all the places in the world inhabited by a certain spider species, and what those places have in common.
  • 35. Oceanography, a related discipline of physical geography, focuses on the creatures and environments of the world’s oceans. Observation of ocean tides and currents constituted some of the first oceanographic investigations. For example, 18th-century mariners figured out the geography of the Gulf Stream, a massive current flowing like a river through the Atlantic Ocean. The discovery and tracking of the Gulf Stream helped communications and travel between Europe and the Americas. Today, oceanographers conduct research on the impacts of water pollution, track tsunamis, design offshore oil rigs, investigate underwater eruptions of lava, and study all types of marine organisms from toxic algae to friendly dolphins.
  • 36. HUMAN GEOGRAPHY Human geography is concerned with the distribution and networks of people and cultures on Earth’s surface. A human geographer might investigate the local, regional, and global impact of rising economic powers China and India, which represent 37 percent of the world’s people. They also might look at how consumers in China and India adjust to new technology and markets, and how markets respond to such a huge consumer base. Human geographers also study how people use and alter their environments. When, for example, people allow their animals to overgraze a region, the soil erodes and grassland is transformed into desert. The impact of overgrazing on the landscape as well as agricultural production is an area of study for human
  • 37. Finally, human geographers study how political, social, and economic systems are organized across geographical space. These include governments, religious organizations, and trade partnerships. The boundaries of these groups constantly change. The main divisions within human geography reflect a concern with different types of human activities or ways of living. Some examples of human geography include urban geography, economic geography, cultural geography, political geography, social geography, and population geography. Human geographers who study geographic patterns and processes in past times are part of the sub discipline of historical geography. Those who study how people understand maps and geographic space belong to a sub discipline known as
  • 38. Many human geographers interested in the relationship between humans and the environment work in the sub disciplines of cultural geography and political geography. Cultural geographers study how the natural environment influences the development of human culture, such as how the climate affects the agricultural practices of a region. Political geographers study the impact of political circumstances on interactions between people and their environment, as well as environmental conflicts, such as disputes over water rights. Some human geographers focus on the connection between human health and geography. For example, health geographers create maps that track the location and spread of specific diseases. They analyze the geographic disparities of health-care access. They are very interested in the impact of the environment on human health, especially the effects of environmental hazards such as radiation, lead poisoning, or water pollution.

  • 41. THE GLOBE A globe is a three-dimensional, spherical, scale model of Earth (terrestrial globe or geographical globe) or other celestial body such as a planet or moon. While models can be made of objects with arbitrary or irregular shapes, the term globe is used only for models of objects that are approximately
  • 42.
  • 43.  Latitude Lines Imaginary lines running horizontally around the globe. Also called parallels, latitude lines are equidistant from each other. Each degree of latitude is about 69 miles (110 km) apart. Zero degrees (0°) latitude is the equator, the widest circumference of the globe. Latitude is measured from 0° to 90° north and 0° to 90° south—90° north is the North Pole and 90° south is the South Pole.  Longitude Lines Imaginary lines, also called meridians, running vertically around the globe. Unlike latitude lines, longitude lines are not parallel. Meridians meet at the poles and are widest apart at the equator. Zero degrees longitude (0°) is called the prime meridian. The degrees of longitude run 180° east and 180° west from the prime meridian.
  • 44.  Equator Zero degrees latitude. The Sun is directly overhead the equator at noon on the two equinoxes (March and Sept. 20 or 21). The equator divides the globe into the Northern and Southern hemispheres. The equator appears halfway between the North and South poles, at the widest circumference of the globe. It is 24,901.55 miles (40,075.16 km) long  Hemisphere a half of the earth, usually as divided into northern and southern halves by the equator, or into western and eastern halves by an imaginary line passing through the poles.  Grid latitude and longitude lines form an imaginary grid over the Earth’s surface.
  • 45.  Prime Meridian Zero degrees longitude (0°). The prime meridian runs through the Royal Greenwich Observatory in Greenwich, England (the location was established in 1884 by international agreement). The prime meridian divides the globe into the Western and Eastern hemispheres. The Earth's time zones are measured from the prime meridian. The time at 0° is called Universal Time (UT) or Greenwich Mean Time (GMT). With the Greenwich meridian as the starting point, each 15° east and west marks a new time zone. The 24 time zones extend east and west around the globe for 180° to the International Date Line.
  • 46.  International Date Line Located at 180° longitude (180° E and 180° W are the same meridian). Regions to the east of the International Date Line are counted as being one calendar day earlier than the regions to the west. Although the International Date Line generally follows the 180° meridian (most of which lies in the Pacific Ocean), it does diverge in places. Since 180° runs through several countries, it would divide those countries not simply into two different time zones, but into two different calendar days.
  • 47.  Tropic of Cancer A line of latitude located at 23°30' north of the equator. The Sun is directly overhead the Tropic of Cancer on the summer solstice in the Northern Hemisphere (June 20 or 21). It marks the northernmost point of the tropics, which falls between the Tropic of Cancer and the Tropic of Capricorn.  Tropic of Capricorn A line of latitude located at 23°30' south. The Sun is directly overhead the Tropic of Capricorn on the summer solstice in the Southern Hemisphere (Dec. 20 or 21). It marks the southernmost point of the tropics.  Arctic Circle A line of latitude located at 66°30' north, delineating the Northern Frigid Zone of the Earth.
  • 48.  Antarctic Circle A line of latitude located at 66°30' south, delineating the Southern Frigid Zone of the Earth.  Globe The most accurate map of the Earth, duplicating its spherical shape and relative size.
  • 49. MAPS  Map Representation of a physical plane with selective information. Maps represent a definite area and contain detailed geographical information.
  • 50. TYPES OF MAPS  Political Map: A political map does not show any topographic features. It instead focuses solely on the state and national boundaries of a place. They also include the locations of cities - both large and small, depending on the detail of the map.
  • 51. Physical Map: A physical map is one that shows the physical landscape features of a place. They generally show things like mountains, rivers and lakes and water is always shown with blue. Mountains and elevation changes are usually shown with different colors and shades to show relief. Normally on physical maps green shows lower elevations while browns show high elevations.
  • 52.  Topographic Map: A topographic map is similar to a physical map in that it shows different physical landscape features. They are different however because they use contour lines instead of colors to show changes in the landscape.
  • 53.  Climate Map: A climate map shows information about the climate of an area. They can show things like the specific climatic zones of an area based on the temperature, the amount of snow an area receives or average number of cloudy days.
  • 54.  Economic or Resource Map: An economic or resource map shows the specific type of economic activity or natural resources present in an area through the use of different symbols or colors depending on what is being shown on the map.
  • 55.  Road Map: A road map is one of the most widely used map types. These maps show major and minor highways and roads (depending on detail) as well as things like airports, city locations and points of interest like parks, campgrounds and monuments.
  • 56.  Thematic Map: A thematic map is a map that focuses on a particular theme or special topic and they are different from the six aforementioned general reference maps because they do not just show natural features like rivers, cities, political subdivisions, elevation and highways.
  • 58. CLASSIFICATION OF MAPS  REFERENCE OR NAVIGATIONAL MAPS are created to help you navigate over the earth surface. These kinds of maps show you where particular places are located and can be used to navigate you way to them. A street map or the common highway road map falls into this category. Physical geographers use topographic maps to show the locations of landscape features on the earth.
  • 59. CLASSIFICATION OF MAPS  TOPOGRAPHIC MAPS illustrate the horizontal and vertical positions (relief) of land surface features. Topographic maps use contour lines to show elevation (height above sea level).  THEMATIC MAPS are used to communicate geographic concepts like the distribution of densities, spatial relationships, magnitudes, movements etc. World climate or soils maps are notable examples of thematic maps.
  • 60. MAP ESSENTIALS TITLE Shows what the subject of the map is. COMPASS ROSE It has arrows which point in all 4 principal directions. SCALE Used to represent distances between two points on a map.
  • 61. BAR SCALE A scale on a map which gives distances in miles or kilometers using bars. LEGEND Used to explain what the symbol on a map represents. KEY Another name for a legend on a map. LOCATOR MAP Shows where in the world the area on the map is located.
  • 62. PRINCIPAL DIRECTIONS The four directions found with a compass - North, South, East, and West. CARDINAL DIRECTIONS Another name for the principal directions. POLITICAL MAPS Maps which show the major political features of a region. POLITICAL FEATURES They include country borders, capital cities and other features. CAPITAL CITIES They are shown as a star on a map. PHYSICAL MAPS Maps which show the major physical feature of a region.
  • 63. PHYSICAL FEATURES They include mountains ranges, rivers, oceans, islands, deserts and plains. SPECIAL PURPOSE MAPS Maps which focus on one special topic like climate, resources or population. LINE SCALE A scale an a map which gives distances in miles or kilometers using lines.
  • 64. MAP PROJECTION  Cylindrical: In standard presentation, these map regularly-spaced meridians to equally spaced vertical lines, and parallels to horizontal lines.  Pseudocylindrical: In standard presentation, these map the central meridian and parallels as straight lines. Other meridians are curves (or possibly straight from pole to equator), regularly spaced along parallels.
  • 65.  Pseudoazimuthal: In standard presentation, pseudoazimuthal projections map the equator and central meridian to perpendicular, intersecting straight lines. They map parallels to complex curves bowing away from the equator, and meridians to complex curves bowing in toward the central meridian. Listed here after pseudocylindrical as generally similar to them in shape and purpose.  Conic: In standard presentation, conic (or conical) projections map meridians as straight lines, and parallels as arcs of circles.
  • 66.  Pseudoconical: In standard presentation, pseudoconical projections represent the central meridian as a straight line, other meridians as complex curves, and parallels as circular arcs.  Azimuthal: In standard presentation, azimuthal projections map meridians as straight lines and parallels as complete, concentric circles. They are radially symmetrical. In any presentation (or aspect), they preserve directions from the center point. This means great circles through the central point are represented by straight lines on the map.
  • 67.  Other: Typically calculated from formula, and not based on a particular projection  Polyhedral maps: Polyhedral maps can be folded up into a polyhedral approximation to the sphere, using particular projection to map each face with low distortion.  Retroazimuthal: Direction to a fixed location B (by the shortest route) corresponds to the direction on the map from A to B.

  • 71. FLORA AND FAUNA  Fauna derives from the name of a Roman goddess, but the handiest way to remember flora and fauna is that "flora" sounds like flowers, which are part of the plant world, and fauna sounds like "fawn," and fawns are part of the animal kingdom.
  • 72.  Flora and fauna refer to plant and wildlife, respectively. The term is often used to refer to the indigenous plant and wildlife of a geographical region. Both are collective terms, referring to groups of plant or wildlife specific to a region or a time period. For example, the flora and fauna of a warm region may consist of tropical to warm- temperate vegetation and exotic species of birds.
  • 73.  By definition, flora is a word of Latin origin referring to Flora, the goddess of flowers. The term can refer to a group of plants or to bacteria. Flora is the root of the word floral, which means pertaining to flowers. Fauna can refer to the animal life or classification of animals of a certain region, time period, or environment. The term is also of Latin origin, and in Roman mythology, Fauna was the sister of Faunus, a good spirit of the forest and plains.
  • 74.  The flora and fauna of any given region are usually explained in biological terms to include the genus and species of plant and animal life, their preferred growing or breeding habits, and their connection to one another in the environment as well. In addition to geographical groupings, environment also helps further their classification. For example, aquatic flora and fauna of a region refers to the plant and animal life found in the waters in or surrounding a geographic region.
  • 75. THE IMPORTANCE OF FLORA AND FAUNA TO HUMAN EXISTENCE ON EARTH  Flowers and animals; we can't live without them. The flora of the earth produce the oxygen that is breathed by the fauna and in turn, the fauna exhale the carbon dioxide that the flora need to live. One cannot live without the other, and humans cannot live without either; hence their importance.
  • 76.  Flora and fauna are the plant and animal life of a region in a period of time. That may sound simple, but the ecosystem created by the interdependence of these two life forms is not simple at all. In fact, humans cannot breathe unless both flora and fauna survive and thrive on the earth.
  • 77.  The very air we breathe and the food we eat, the medicines that cure us, and the water that keeps us alive would not exist were it not for flora and fauna. All things in an ecosystem are interdependent. The existence of one species may depend on the health of another, such as the relationship of bamboo forests to pandas. Pandas only eat bamboo shoots, so the destruction of the bamboo forests in China resulted in the endangerment of the Panda, due to starvation and loss of habitat.
  • 78.  In China, destruction of the forests left the tigers with no place to go. Farmers killed them in great numbers to protect their farm animals, and soon there were few left. In an attempt to save the species, Chinese tigers were moved to the forests of Africa, where they are surviving nicely.
  • 79. ENDANGERMENT OF OCEAN FLORA AND FAUNA  The importance of flora and fauna in the oceans cannot be underestimated, many of which are endangered or extinct due to pollution and other of man's actions.  Excessive dumping of nitrogen rich fertilizers into the Gulf of Mexico has created the growth of huge colonies of red algae, called "red tide", which kills millions of ocean creatures every year, and even a few hypersensitive humans.
  • 80.  The mass killing of sharks has created a dangerous overpopulation of sting rays. Overfishing and whaling in Japan has caused many species of whales to be seriously endangered.  The Great Barrier Reef, home to millions of the ocean's species, is dying due to pollution and rising water temperatures, which is causing a ripple effect unlike any we will ever again see.
  • 81. GLOBAL EFFECTS OF THE DESTRUCTION OF FLORA AND FAUNA  The importance of flora and fauna cannot be seen anywhere as distinctly as in our rainforests. The Amazon rainforest once gave us 20% of our oxygen supply. As their destruction has progressed, so has the incidence of respiratory illness around the world. Some of our most effective drugs come from rainforest plants. Destruction of these plants, and their habitats, will not only affect our health, but our very lives.
  • 82.  Half of the world's species of plants, animals and microorganisms have become endangered or extinct due to this pernicious destruction of the rainforest. Birds and animals are in part responsible for keeping the rainforest alive, by spreading seeds through their feces. Without them, many plant species cannot propagate, and will disappear.
  • 83. MAN'S DESTRUCTION OF ECOSYSTEMS  Man, in his quest for money and power, has created a world in which the ecological balance of flora and fauna has been destroyed, in many instances causing the extinction of entire species due to destruction of habitat and food sources.  Manmade "acid rain" killed entire forests when it blew into Canada and fell on the trees there. Smog has killed plants, animals and even humans. The hole in the ozone, said to be the main cause of the melting arctic ice caps, is (like acid rain) believed to be caused by the foul emissions of coal burning factories.
  • 84. GLOBAL ACTIONS CAUSE LOCAL CONSÉQUENCES The world's ecology is so complex, so fragile, so interdependent, that an ecological upheaval of the flora and fauna of one region of the world (i.e. the destruction of rainforests) can affect the entire planet. Global trade has introduced species to areas outside of their natural habitat, where there are no predatory species to control their destructive habits. Fire ants were brought to the United States in a cargo ship. They have caused the death of livestock, people, and many native species of ants and insects. You need look no further than Florida to see the importance of native flora and fauna on the local ecosystems.
  • 85. Plants like Kudzu, Brazilian Pepper, Australian Pine, and Chinese Tallow were brought in from other countries to the United States and have invaded and destroyed entire habitats of native flora. The Everglades is being destroyed by Malaleuca, which was seeded by airplanes to dry up the Everglades and allow sugar cane to be planted after the Cuban embargo. The introduction of non-native brown anoles and Cuban tree frogs into Florida has nearly caused the extinction of native lizard and toad species, which are their prey. Iguanas and other large lizard species, as well as large snakes such as boas and pythons, are invading the Everglades and other ecologically sensitive areas.
  • 86. In fact, Florida and its port cities have introduced and become invaded by more invasive non-native species than any other state in the U.S. Imports of salmon eggs into Japan have caused outbreaks of disease into several of their native fish species, causing great economic and ecological losses. The list goes on indefinitely. The University of Arizona site tells a shocking tale of the ecological and economic cost of invasive flora and fauna to the U.S. alone every year.
  • 87. WHAT CAN BE DONE? The situation simply is out of control, and although many organizations such as Greenpeace and the World Wildlife Fund, as well as local societies and agencies worldwide are trying, there may be no solution. The indigenous flora and fauna of the world are dying, and the ecosystem as we know it is dying with them. It has been said, that if insects decided to take over the world, we would all be doomed. If things keep going the way they are, they may just have their chance.
  • 88.  Locally, you can find organizations that are working to teach the importance of flora and fauna native to your area and volunteer or donate money. Globally, you can join organizations like the World Wildlife Fund and support their worldwide mission to save the flora and fauna that support the world's ecological systems.
