Which statement best describes a convex slope’s contour spacing from bottom to top?

• A. Closer together at the bottom and wider apart at the top
• B. Closer together at the top and wider apart at the bottom
• C. Even spacing
• D. Random spacing

Answer: (A)

Contour spacing shows how steep the terrain is. When contour lines are close together, the elevation changes quickly over a short distance, indicating a steep slope; when they are farther apart, the slope is gentler. A convex slope curves outward, meaning it is steeper near the bottom and becomes less steep as you go up. So the lines will be tightly packed at the bottom and spread farther apart toward the top.
