The Basics of Geography
Chapters 1 — 4
Chapter 1 – The Five Themes of
Geography
Chapter Overview
This chapter explains the Five
Themes of Geography, and
describes such tools of
geographers as maps, globes,
satellite images, and Geographic
Information Systems (GIS).
Section 1: The Five Themes of
Geography



Geographers study the use of space on
earth.
Geographers organize information
about geography into five categories
or themes.
The Five Themes of Geography are
location, place, region, movement, and
human-environmental interaction.
Section 1: The Geographers
Perspective
Geography The study of the distribution
and interaction of physical
and human features on the
earth.
Human Geography The study of the humans and
their interaction with one
another and the environment.
Physical Geography The study of the physical
features found on earth.
Physical and Human Features
on Earth
Five Themes of Geography:
Location
Location “Where is it?”
 Described in two ways:
absolute and relative.
Absolute Location The exact place on earth
where a feature is found (e.g.
a city).
Relative Location Describes a place in
comparison with other places
around it (e.g. direction, time,
or direction).
Five Themes of Geography:
Location
Grid System A system of lines to locate
absolute locations on earth’s
surface.
Hemisphere One half of the globe (e.g.
Northern, Southern, Eastern,
Western).
Equator Imaginary line that divides North
and South.
Five Themes of Geography:
Location
Prime Meridian Imaginary line that divides East
and West.
 Also known as the Greenwich
Meridian because the line runs
through Greenwich, England.
Latitude Imaginary lines that run
parallel to the equator.
Longitude Imaginary lines that go around
the earth over poles.
Five Themes of Geography:
Place
Place “What is it like?”
 Place includes the physical
and cultural characteristics
of a location.
 Physical features include
climate, landforms, and
vegetation.
 Human features include
buildings, structures, and
cultural elements.
Five Themes of Geography:
Region
Region “How are places similar or
different?”
 A region is an area of the
earth’s surface with similar
characteristics.
 Features can include
physical, political,
economic, or cultural
characteristics.
 There are three types of
regions: formal, functional,
and perceptual.
Five Themes of Geography:
Region
Formal Region Defined by a limited number
of characteristics.
 The formal region discussed
this semester will include:
- Southwest Asia & North Africa
- Sub-Saharan Africa
- South Asia
- East Asia
- Southeast Asia, Oceania,
and Australia
- Europe
- Russia & the Republics
- Latin America
- Canada & the United States
Five Themes of Geography:
Region
Functional Regions Organized around a set of
interactions and connections
between places (e.g. a city
and its suburbs).
Perceptual Regions A region in which people
perceive, or see, the
characteristics of the region
in the same way (e.g. the
Midwest may be defined
differently by people).
Five Themes of Geography: HumanEnvironmental Interaction
Human-Environmental
Interaction “How do people relate to
the physical world?”
 People learn to use what the
environment offers them
and to change the
environment to meet their
needs.
 People also adapt to live
within the limits of their
environment.
Five Themes of Geography:
Movement
Movement “How do people, goods, and
ideas move from one
location to another?”
 Examples of movement
include clothing, music, or
places of entertainment.
 Geographers analyze
movement by looking at
three types of distance:
linear, time, and
psychological.
Five Themes of Geography:
Movement
Linear Distance How far an idea, person, or
product travels and how it
is affected by physical
geography.
Time Distance The amount of time it takes
an idea, person, or product
to travel.
Psychological Distance The perception of how
people view an idea,
person, or product travels.
Section 2: The Geographers Tools
Two basic tools of geographers are maps and
globes.
 Most mapmaking today relies on data
gathered by remote sensing, primarily by
aerial photography or by satellites.
 Other important tools of geographers are
Geographic Information Systems (GIS) and
Global Positioning Systems (GPS).

Maps & Globes
Globe A 3-D representation of the earth.
Map A 2-D representation of the earth.
 Portable and can be drawn to scale.
Cartographer A Mapmaker.
Map Projection A way of drawing the earth’s
surface to reduce distortion caused
by presenting a round earth on a
flat service.
Types of Maps
Thematic Maps Emphasize specific kinds of
information (e.g. climate or
population).
Navigational Maps Used by sailors and pilots to plot
distance and direction.
Topographical Maps Highlights general references (e.g.
natural or man-made features).
Surveying
Field Survey Surveyors observe, measure, and
record a specific area based on what
they can see.
Mapping & Remote Sensing From a distance, information is
gathered from aerial photography
(e.g. satellites) and stored for use.
Data Collection Includes information (e.g. elevation,
land cover, and variations of
temperature) which is used to
construct maps.
Satellites
Landstat A series of satellites which orbit
above the earth and can collect
data.
Geostationary Operational
Environmental Satellite (GOES) A weather satellite which can
orbit in sync with the earth’s
rotation to view the same area
and is used to forecast weather.
Geographic Informal Systems
(GIS) & Global Positioning
Geographic Information Systems
(GIS) GIS stores information about
the world in a digital database.
Global Positioning System (GPS) The system uses a system of 24
satellites to find exact positions
on the earth’s surface by
tracking latitude, longitude,
altitude, and time.
 GPS is used by hikers, sailors,
and drivers.
Map Projections
Planar (Azimuthal) Projection A projection on a flat surface.
 Distorts size and shape.
Conical Projection A projection onto a cone.
 Shape is accurate, but distorts
landmasses at the edge.
Compromise Projection A projection onto a cylinder.
 Three types of compromise
projections: Mercator, Robinson,
and homolosine.
Types of Maps
Physical Maps Help identify land features and
bodies of water.
 Shows relief, contour lines,
and shading.
Political Maps Shows features created by
humans.
 Shows cities, states, provinces,
territories, or nations.
Types of Maps
Thematic Maps Focuses on specific types of
information.
 Shows climate, vegetation,
natural resources, population
density, and economic
activities.
Flow-Line Maps Illustrates the movement of
people, goods, animals, or
glaciers.
 Shows location and direction
of movement can be seen.
Chapter 2 – Physical Geography:
A Living Planet
Chapter Overview
This chapter describes the
physical structure of the
earth and the internal and
external forces that shape the
planet.
Section 1: The Earth Inside and
Out
The earth is the only habitable planet in our
solar system.
 The earth consists of a series of shelves that
float on one another.
 The theory of the continental drift explains
the formation of the continents.

The Solar System
Solar System The solar system consists of
the sun and the nine known
planets, as well as the celestial
bodies that orbit the sun.
 The solar system also consists
of the comets, asteroids, and
other space debris orbiting
the sun.
Inside the Earth
Core The center of the earth and is
made up of nickel and iron.
Mantle Surrounds the core and is made
up of several layers.
Magma Found in the mantle and made
up of molten rock.
Crust Thin layer of rock at the earths
surface.
On & Above the Earth
Atmosphere Layer of gases which contains the
oxygen we breathe, protect the
earth from space debris, and
provide a medium for weather
and climate.
Lithosphere The solid rock portion of the
earth’s surface which make up
the uppermost mantle and crust.
 Also makes up the land masses
on the floor of the earth’s oceans
and the seven continents.
On & Above the Earth
Hydrosphere Made up of the water elements
on the earth’s surface which
include the oceans, rivers, lakes,
and water in the atmosphere.
Biosphere Made up of the lithosphere,
atmosphere, and hydrosphere
and is the part of the earth
where plants and animals live.
Continental Drift
Alfred Wegener German scientist who
presented a theory in 1912
called the “Continental
Drift” hypothesis.
Continental Drift Theory maintains that the
earth was once a supercontinent (Pangaea) that
divided and slowly drifted
apart for millions of years.
Section 2: Bodies of Water &
Landforms
Water covers three-fourths of the earth’s
surface and makes life possible.
 The water on earth is continuously
circulated between the atmosphere, the
oceans, and the earth.
 The ocean floor and the continents have
similar landforms.

Oceans & Motion
Oceans The interconnected body of
saltwater that covers 71% of the
earth’s surface.
 Geographers divide the oceans
into four main parts: Pacific,
Atlantic, Indian, and Arctic.
Ocean Motion The salty water of the ocean
circulates through three basic
motions: currents, waves, and
tides.
Oceans & Motion
Currents Act like rivers flowing through
the ocean moving water from
one area to another.
Waves Swells or ridges produced by
wind.
Tides The regular rise and fall of the
of the ocean created by the
moon and the sun.
Oceans & Motion
Transfer of Heat The motion of the ocean helps
regulate and distributes the
heat on the planet.
 Winds blow over the oceans
and are cooled or heated.
 Eventually, winds reach the
land and moderate the
temperature and air over the
land.
Hydrologic Cycle
Cycle of Water The hydrological cycle is the
continuous circulation of water
between the atmosphere, the
oceans, and the land.
(1) Water is heated and evaporates into the
atmosphere;
(2) as vapor, the water cools as it rises and
condenses;
(3) Clouds become saturated and the
condensed water falls to the earth as
rain, sleet, or snow;
(4) Water soaks into the ground, evaporates
into the atmosphere, or flows into rivers
to be recycled.
Lakes, Rivers, & Streams
Lakes Hold more than 95% of all the
fresh water and are usually the
result of glacier action from the
past.
Rivers & Streams Flow through channels and move
water to larger bodies of water.
Drainage Basin A area drained by a major river or
tributary.
Landforms
Landforms Naturally formed features on the
earth’s surface
Continental Shelf The edge of a continent to the
deep part of the ocean.
Ocean Landforms The floor of the ocean has ridges,
valleys, canyons, and plains.
 Islands raise above the surface of
the ocean from the ocean floor.
Landforms
Relief The major geographic feature
that separates one type of
landform from another relief.
Topography The combination of the
surface shape and
composition of the landforms
and their distribution in a
region.
Section 3: Internal Forces
Shaping the Earth
 The
earth’s crust consists of a number
of tectonic plates.
 The movement of the tectonic plates
continually reshapes the surface of the
earth.
 Movement of the plates produces
earthquakes and volcanoes.
Plate Tectonics
Tectonic Plates Large pieces of the lithosphere
which form one of three types of
boundaries: divergent, convergent,
or transform.
Divergent Boundary Plates move apart, horizontally
Convergent Boundary Plates collide causing one plate to
slide under another.
Transform Boundary Plates slide past one another.
Folds & Faults
Fold Changes in the crust caused
by the slow movement of
rock under great pressure.
 Folds create the
transformation of the crust
and only occurs in a few
centimeters or inches a year.
Fault The fracture in the earth’s
crust in which plates move
past one another.
Earthquakes
Earthquakes The sliding or colliding of
tectonic plates causing the
earth to shake or tremble.
Seismograph Detects earthquakes by
measuring the size of the
waves created by an
earthquake.
Epicenter The point directly above
where the center of the
earthquake occurred.
Earthquake Damage
Results of Earthquakes Earthquakes squeeze, stretch,
and shear the land and
structures by resulting in
damage.
Richter Scale Uses the information collected
by seismographs to determine
the strength of an earthquake.
Tsunami A large wave in the ocean
usually caused by an
earthquake.
Volcanoes
Volcano A crack in the earth’s surface.
Lava Magma which reaches the
earth’s surface.
Ring of Fire A zone around the rim of the
Pacific Ocean where a vast
majority of active volcanoes
exist.
 Eight of the major tectonic
plates meet at this zone.
Section 4: External Forces
Shaping the Earth
 Weathering
and erosion alter the
surface of the earth.
 Water, wind, and glaciers cause erosion
that produces a variety of landforms.
 Weathering and erosion help form soil.
Weathering
Weathering Refers to the physical and
chemical processes that
change the characteristics of
rock.
Sediment Identified as mud, sand, or
silt.
Weathering
Mechanical Weathering Only changes the size of the
rock, not its composition.
 When ice crystals can cause a
rock to fracture into smaller
pieces.
Chemical Weathering Occurs when rock is changed
into a new substance as a
result of the interaction
between air, water, and
minerals.
 Minerals can break down
when exposed to O or C.
Wind & Water Erosion
Erosion Occurs when weathered material
is moved by the action of wind,
water, ice, or gravity (e.g. glaciers,
waves, flow of water, or blowing
wind).
Delta When a river enters the ocean, the
sediment is deposited in a fan-like
V-shaped landform.
Loess Windblown silt and clay sediment
that produces fertile soil.
Building Soil
Forming Soil Weathering and erosion are part
of the process of forming soil.
 Organic matter in the soil helps
support plant life as well as water
and air.
 The variety of soils and the
climate in which they are found
determine the types of
vegetation.
Humus The amount of organic material
found in soil.
Chapter 3 – Physical Geography:
Climate & Vegetation
Chapter Overview
This chapter explains the causes
of the seasons, weather, and
climates, and describes the
world’s climate and vegetation
regions.
Section 1: Seasons & Weather
Seasons are caused by the earth’s tilt and
revolution around the sun.
 Daily weather is the result of many factors,
including solar energy, water vapor, cloud
cover, landforms, bodies of water, and air
movement.
 Types of extreme weather include
hurricanes, tornadoes, blizzards, droughts,
and floods.

Seasons
Earth’s Tilt & Revolution The seasons exist due to both
the tilt of the earth on its axis
and revolution of the earth
around the sun.
 Some locations receive more
direct sun rays because of the
earth’s tilt.
Tropics of Cancer & Capricorn The farthest points (north and
south in relation to the equator)
that the sun’s rays shine directly
overhead at noon.
Seasons
Solstice The seasons of summer (June 21)
and winter (December 22) begin.
 The farthest points (north and
south in relation to the equator)
that the sun’s rays shine directly
overhead at noon.
Equinox The seasons of spring (March 21)
and fall (September 23) begin.
 Day and night are equal in length.
Weather
Weather The condition of the
atmosphere at a particular
location and time.

particular location over a long
period of time.
Precipitation Falling water droplets in the
form of rain, sleet, snow, or hail.
Weather Extremes

current, latitude, altitude, and
topography.
 Climates change over time.
 Some climate changes are natural,
while others result from human
activities.
Factors Affecting Climate
Wind Currents Distribute heat from the one part
of the world to another part of
the world.
 Winds are caused by Convection
or the transfer of heat in the
atmosphere in an upward motion
of the air.

circulated to higher latitudes and
cold water flows back to the
equator.
Factors Affecting Climate
Zones of Latitude Low or tropical.
 Middle or temperate.
 High or polar.
Elevation The distance above sea level.
 Temperature decreases as altitude
increases.
Topography Mountains trap moist air on one
side and cause dry conditions on

coast of South America which
occurs every two to seven years.
 Brings heavy rain to the
Americas.
La Nina The cooling of waters off the
coast of South America which

Changes in Climate
Global Warming The increasing temperature of
the earth.
 Controversy exists as to the
actual causes of the warming.
Greenhouse Effect The layer of gases (released by
the manmade and natural
causes) into the atmosphere
causing higher temperatures in
the same way a greenhouse
traps solar energy.
Section 3: World Climate
Regions
 Climate
region definitions tell what
typical weather conditions are like in a
region.
