|
|
|
What is a map's scale?
|

|
|
|
How many degrees are there between the Equator and the North Pole?
|
There are 90 Degrees.
|
|
|
How do mapmakers represent elevation, relief, and slope?

|
|
|
How do you read a topographic map?
|
To read a topographic map, you must know the map's scale and symbols and interpret the map's contour lines.
|
|
|
Topographic map
|
A map showing the surface features of an area.
|
|
|
Contour Line
|
The lines on a map that connects points of equal elevation.
