What is a topographic map? U.S. Geological Survey . Contours make it possible to show the height and shape of mountains, the depths of the ocean bottom, and the steepness of slopes. USGS topographic maps also show many other kinds of geographic features.

Contour lines show stream direction with the V-shaped lines through which you see the streams and rivers run through on a topo map. Because water flows downhill, the V-shape always points in the opposite.
