5 Themes of geography
Unit 1
World Geography
What are the
five themes?

Tools
geographer’s use
to study features
on earth.
•Location
•Place
•Movement
•Region
•Human
Environment
Interaction
What is geography?



The study of spatial
variation
How – and why –
things differ from
place to place on the
surface of the earth
The study of how
observable spatial
patterns evolved
through time




Geography is a
spatial science
Spatial behavior of
people
Spatial relationships
between places
Spatial processes
that create or
maintain those
behaviors and
relationships

Location: Describes where
places are at on earth.
ABSOLUTE:
• exact location on
earth (fixed)
 Doesn’t change
• Latitude/Longi
tude
• Hemispheres
• Grid System
• Address
RELATIVE:
• compared to other
places (variable)
 Changes
dependent upon
where you’re
comparing it to.
• Miles
• Distance
• Direction
Imaginary lines running east and west around the globe
Measured in degrees north and south of the equator.
Latitude lines are called parallels because each line is parallel to the
next
Degrees are units of measurement for latitude and longitude.
The symbol for degrees is °.
The equator is the imaginary line that circles the Earth’s center known
as 0° latitude.
Check out the globe!
North of the equator
EQUATOR
South of the equator
Parallels above the equator are in
the Northern Hemisphere, all below
are in the Southern Hemisphere
You must write latitude
coordinates like this:
˚
˚
Distance measured in degrees east and west of the prime
meridian.
Longitude lines are called meridians.
The prime meridian is the starting point for measuring
longitude.
The prime meridian is 0 longitude which goes through
the space observatory in Greenwich, England.
Check out the Globe!
Meridians west of the prime meridian are
in the western hemisphere, all in the east
of the prime meridian are in the eastern
hemisphere.
You must write longitude
coordinates like this:
˚
˚
HEMISPHERES

Five Themes of Geography:
Place

Geographers study this geography
theme by looking at the
characteristics that distinguish one
place from another place on Earth.
PLACE
What is it like there, what kind of
place is it?
 Human
 Physical
Characteristics
Characteristics


What are the main
languages, customs,
and beliefs.
How many people live,
work, and visit a place.

Landforms (mountains,
rivers, etc.), climate,
vegitation, wildlife, soil,
etc.

Themes of Geography
Regions
What is a Region?



Concept that is used to identify and
organize areas of Earth’s surface for
various purposes.
Has certain characteristics that give it a
measure of cohesiveness and
distinctiveness that set it apart from
other regions.
As worlds within worlds, can be used to
simplify the whole by organizing Earth’s
surface on the basis of the presence or
absence of selected physical and human
characteristics.
Types of regions

Formal,
Functional
and
Perceptual.
FORMAL
PERCEPTUAL
FUNCTIONAL
designated by
official
boundaries,
such as cities,
states, counties,
and countries.
place where
peoples beliefs
exists as part of
their cultural
identity
tied by a
central point by
transportation or
communications
systems or by
economic or
functional
associations.
Formal



Also called homogeneous region.
An area within which everyone
shares in common one or more
characteristics such as language,
production of a particular crop or
climate
Formal regions can be defined by
measures of population, per capita
income, ethnic background, crop
production, population density and
distribution, or industrial
production, or by mapping physical
characteristics such as
temperature, rainfall, growing
season, and average date of first
and last frost.
Vernacular



Also called perceptual region.
perceived regions, such as "The
South," "The Midwest," or the
"Middle East;" they have no
formal boundaries but are
understood in our mental
maps of the world.
tends to reflect the element of
people’s mental maps, and,
although it may help to impose
a personal sense of order and
structure on the world, it often
does so on the basis of
stereotypes that may be
inappropriate or incorrect
Functional



An area organized around a
focal point.
For example, the
newspaper circulation area
for a major city area is the
functional region of that
paper or the viewing area
of a tv station
A typical functional region
is a metropolitan area (MA)
as defined by the Bureau of
Census.
Movement
Movement


How Do People,
Goods, and
Ideas Get from
One Place to
Another?
Geographers
use three types
of distance to
analyze
movement
Types of Movement

Linear Distance



Time Distance
Psychological Distance
Examples of movement include America's
westward expansion, the Information
Revolution, and immigration.
Linear Distance

How far a
person, product,
or idea travels
Time Distance

How long it
takes for person,
product, idea to
travel
Psychological Distance


Refers to the way
people perceive
distance
Example:
unfamiliar places
may seem
farther away
than familiar
ones
Human Environment interaction


How Do People Relate
to the Physical
World?
A relationship exists
between people and
their environment
Human Environment Interaction



People use and change
the environment to
meet their needs
People adapt to
environmental
conditions they cannot
change
Often, people in similar
environments adapt in
different ways
