Closed backward contour lines indicate depressions. What term describes these lines?

Explanation:
Contour lines are the map lines that connect points of equal elevation. When they form closed loops and the elevation lowers toward the center, you’re seeing a depression. The lines themselves are still contour lines—the term describing them in this case. Hachures are short relief lines used to show slope direction, not the general line type. Halftone and tint refer to shading or tonal techniques, not the contour lines themselves.
