The World of Geography
Section 1
The Five Themes of Geography
Geography
Is the study of the Earth
Geographers are guided by
two basic questions:
Where are things located???
Why are they there???
To find the answers, geographers
use themes to organize information
Location: where a point exists
Place: a location’s physical and human
features
Human Environment interaction: how people
affect their environment
Movement: How goods, ideas, and people
get from one place to another
Regions: Large areas that are linked by
similar characteristics
Location
Absolute location
A places exact
position on Earth
(geographic address)
Uses latitude and
longitude
Relative location
Explains where a
place is by
describing places
near it.
“I live in Bismarck,
190 miles west of
Fargo”
Location
Lines of Latitude:
Parallels:
Another name for lines of latitude, because
they are parallel to one another
Degrees:
East-West circles around the globe
Unit used to measure location on maps
Equator:
A parallel in the middle of the globe
Location
Lines of Longitude:
Meridians:
Lines that circle the globe from North-South
Another name for lines of Longitude
All run through the North and South Poles
Prime Meridian:
Runs though Greenwich, England
Is 0 degrees longitude
Latitude and Longitude
Latitude
Measured North and South of Equator
Longitude
Measured East and West of Prime Meridian
(Greenwich, England)
Measured in degrees, minutes, seconds
Degree - 69.1 miles
Minute - 1.15 miles
Second - 101 feet
Place
Physical features
Climate - hot or cold
Land is hilly
Human features
How many people live there
What these people do
Human - Environment
Interaction
How have people learned to survive in
the area?
How do they deal with the environment?
Are they helping or hurting the
environment?
Movement
Helps people understand cultural
changes
Goods and people move: bringing their
culture with them
Immigrants to America
Regions
Used to make comparisons
Deserts, forests, plains, mountains
Plain
A region of flat land
Section 2
The Geographer’s Tools
Maps
Globe
The most accurate description
Hard to carry around
Scale
Size of an area on a map compared to the actual
size of an area (1 in= 100 miles)
Flat maps
Easy to carry around
Shows some distortion. (misrepresentation)
Change in the accuracy of the shapes and distances
Maps
Projection - method of putting a map of the Earth
onto a flat piece of paper
Mercator Projection
Gerardus Mercator
Flat map - used by sailors
Shows correct shapes of landmasses, but not true
distances or sizes
Robinson Projection
Arthur Robinson
Best world map available
Distorted around the edges
WAS Official projection for National Geographic – now
Winkle Tripel
More Maps
Interrupted projection map
“Orange Peel”
Hard to figure distances correctly
Distortion
Flat maps distort land masses because the
Earth is round.
Subject of a Map = Title
Parts of a map
Compass rose
Key
Shows the cardinal directions: north, south, east,
and west.
“legend” explains the symbols for features such as
roads and cities.
Grid
Helps people find things on the map
Parallels and meridians
Letters and numbers
