Topographic maps and Contour Lines

What is Topography?  Understanding the surface, shape, and features of the earth  Geographers create topographic maps to showcase the land

What does a topographic map look like?

What is a Contour Line?  A contour line shows different heights on a map.  If the lines are close together then the land is very steep.  If the lines are far apart the land is relatively flat.  If there are no contour lines the land is completely flat.

What does this show us?

Contour Map Rules  Lines on a contour map start at sea level which is 0 degrees  Each line represents an equal change in elevation  Lines very RARELY cross  Base of elevation starts at 0 feet (assuming it’s at sea level)
