Explanation:
The most important information on a topographic map that can be used to compare the steepness of slopes on the map is the contour.
- Contour lines are lines on a map that joins places having equal elevation on a map.
- The nature of the landform in an area can be inferred from the contour lines.
- Where contour lines are close together it signifies rapidly changing topography and thereby, a very steep slope is inferred.
- Where contour lines are wide apart, it signifies a gentle slope.
