Quick Review
What is a hemisphere? What is the line of latitude that
divides the earth in half (north and south)?
What is the line of longitude that divides the earth in half (east and west)?
What hemispheres is the United States located in?
Quick Review
Hemisphere: Half of the Earth Line that divides north and south:
Equator Line that divides east and west:
Prime Meridian Hemispheres of United States: North
and West
Quick Review
Latitude
Line of Latitude measure the distance (in degrees) north and south of the equator
The equator is 0 degrees They run east and west Think “ladder” for latitude
Latitude
Equator
Longitude
Lines of longitude measure the distance (in degrees) east and west of the prime meridian
Prime meridian is 0 degrees International dateline is 180 degrees
What is the international dateline? They run north and south
Longitude
Prime Meridian
International Dateline
Latitude and Longitude
What does the combination of both coordinates give you? Answer: Absolute location Example: Kansas City is 39 degrees N,
98 degrees W Practice: Approximate the
coordinates of Denver, CO using the map on the screen Do the same with Springfield, IL
Map of USA
Maps and Globes
Globe: 3D representation of the earth Pros: see the earth as it really is Cons: only see half at a time
Map: 2D representation of the earth Pros: See the whole world Cons: Can be distorted depending on
type of map A cartographer is someone who
makes maps
Political Maps
Representation of a countries boundaries, territories, cities, capitals, etc.
Shows features that were created by humans
May include roads/train lines, etc. Uses:
Mapping trips Examining regions Analyzing human characteristics
Political Maps
Physical Maps
Representation of the earths physical/natural features, such as elevation, landforms, bodies of water, etc.
Uses: Analyzing geographic features Hiking
Physical Maps
Thematic
Focuses on one type of information
Can go beyond physical geography
Uses: Show a very
specific type of information
Map Components
There are some components most maps will share
They are: Title Compass rose Legend/key Scale Latitude/Longitude
Title – purpose of map
Legend/key – tells us what things on the map mean
Scale – shows us distance
Latitude/longitude – gives us coordinates for locations
Compass rose – shows directions
