Topographic Map


Topographic maps are tools used in geologic studies because they show the configuration of the earth’s surface. On most topographic maps, index contour lines are generally darker and are marked with their elevations. Among other things, a topographic map can be used to measure the average slope of a hill (or hills). This is an example of a piece of land they used to show how a topographic map looks like.
