What is a characteristic of a steep slope on a map?

A steep slope on a map is characterized by a sharp increase in elevation over a relatively short horizontal distance. This is visually represented by closely spaced contour lines on a topographic map. When you see these closely spaced lines, it indicates that the terrain rises quickly, demonstrating the steepness of the slope. Understanding this characteristic is essential for navigation and terrain assessment, as steep slopes can affect movement, visibility, and tactical decisions in the field. The other options represent different types of terrain configurations that do not convey the immediate and significant elevation change seen in steep slopes.
