The Five Themes of GeographyThe 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:
East-West circles around the globe Parallels:
Another name for lines of latitude, because they are parallel to one another
Degrees: Unit used to measure location on maps
Equator: A parallel in the middle of the globe
Location Lines of Longitude:
Lines that circle the globe from North-South
Meridians: 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
