What is a topographic map? The distinctive characteristic of a topographic map is the use of elevation contour lines to show the shape of the Earth's surface. Elevation contours are imaginary lines connecting points having the same elevation on the surface of the land above or below a reference surface, which is usually mean sea level.
Explain how to read and interpret a topographic map. Explain how bathymetric maps are used to determine underwater features. Describe what a geologic map shows.
