If contour lines are close together, what does that indicate about the terrain?

Explanation:
Contour lines show equal elevations, and how close or far apart they are reflects how quickly elevation changes over distance. When lines are packed tightly, you gain a lot of height in a short walk, which means the slope is steep. If the lines are spread apart, the elevation changes slowly, indicating a gentle or flat terrain. So the close spacing directly points to steep terrain.
