What interpretation can be made from closer contour lines on a map?

The presence of closer contour lines on a map indicates steeper slopes. Contour lines represent elevation levels; when these lines are closely spaced, it signifies a rapid change in elevation over a short horizontal distance. This is characteristic of steep terrain where the incline rises sharply, reflecting significant changes in height. In contrast, if contour lines are spaced further apart, the change in elevation is more gradual, suggesting flatter areas. Therefore, the closer the contour lines, the steeper the slope is inferred to be, which accurately supports the choice that indicates steeper slopes.
