1. Landforms and Topographic Maps
There are some basic rules to remember when reading a topographic map. Contour lines never cross. When contour lines are spaced close together, the slope is steep. If they are spread apart, the slope is gentle. Contour lines that cross a valley or stream are V-shaped with the V pointing toward the higher elevation. Tops of hills or depressions are shown as closed circles.
