Geography

What is it?
Geography

The study of where:
–
–
–
People
Places
Things

ARE LOCATED
–
AND how they relate to each other.
Ancient Egypt

Egyptian Priests
–
Studied the land

Why?
–
Land uses
– What the land could produce
– Base a tax system off of the land – supported building
their temples
Greeks

First to create maps of
Europe, Africa, and
Asia.
5 Themes of Geography





Location
Interaction between
people and
environment
Movement
Place
Region
Location

Where is Penncrest High School?

On a sheet of loose leaf try to explain to someone: “where is
the location of Penncrest High School?”

Turn to a neighbor and see how much your explanation is
helpful.

Rate your partner’s explanation:
–
–
–
10 being very helpful (you could find it easily),
1 being not helpful at all (where is Penncrest!?)
5 being helpful but not helpful enough (I might recognize it if I passed it, but I’d
have difficulty finding it).
Relative Location

Did we:
–
–
–
Describe PHS in terms
of another location?
How else did we
describe it?
How do we determine its
EXACT or ABSOLUTE
location?
ABSOLUTE Location

Use grid of numbered lines of latitude and
longitude.

Penncrest is located at:
–
–
39 degrees, 55” N
75 degrees, 26” W
Latitude & Longitude

Latitude
–

Measures distance north and south of the
Equator.
Longitude
–
Measures distances east and west of the
Prime Meridian
Equator

Divides the Earth into two halves (Northern and
Southern Hemisphere.

Line of latitude
Prime Meridian

Divides World
into Eastern
and Western
Hemispheres.

Opposite of
Prime Meridian

characteristics

Think about our PLACE
On a sheet of loose leaf/ note book paper:
Describe Media as a place.
Consider the following:
 Stores
 Landforms
 Religions
 Animal Life
 Weather
 Transportation
Interaction Between People & Environment

How do we interact with our environment?
Hidden Cost

How has interactions with environment
created “hidden costs?”

Farming
Transportation
People adapt

How do people adapt to different
environments?

Interdependence

Global Interdependence
–
Dependence of countries on goods, resources,
and knowledge from other parts of the world.
–
What is something we are dependant on?

Tools of Geographers


Geographers use globes and maps.
Why is a globe more accurate than a map?
What is a drawback of using a
globe?
Map Projection


Show a curved earth on a flat surface.
Accuracy varies depending on type of map.
Mercator Projection

Gerardus Mercator - 1569
–
Sailors needed a map that showed direction
accurately (N/S/E/W)
Mercator Projection
Mercator Projection



Accurate view of land areas NEAR
EQUATOR
Direction (N/S/E/W)
North and South Poles
–
Land becomes distorted
–
What is the problem with using a Mercator
Projection?
Interrupted Projection



Show correct sizes and shapes of
landmasses
Cut-out oceans
Impossible to:
–
–
accurately measure distance
plot a course across an ocean
Interrupted Projection
Peters Projection



Shows correct areas of landmasses and
oceans.
Directions are accurate
Distorts shapes of continents
–
Notice how Africa appears longer and thinner.
Peters Projection
Robinson Projection




Shows correct sizes and shapes of most
landmasses
Fairly accurate view of sizes of the oceans
Fairly accurate view of distance over
landmasses
Distortions along the edge of the map
