Little change in elevation, or a low gradient
When contour lines are farther apart, the elevation is changing less rapidly. Each line represents a certain amount of height. More lines means steeper slope.
gentle slopes
If the topographic lines are closer together it means that it has a steeper slope grade, if they are farther apart, it means that they have a more relaxed slope grade. There is usually a scale on the map that can tell you in exact measurements of the slope.
nearly flat
On a map they would indicate a steep slope And on a synoptic chart they would indicate stronger winds the closer they are. Depends on the differences in barometric pressure between the isobars.
This indicates steeply ascending or descending terrain. The distance between the lines indicates different elevations, so lines that are closer together indicate steep places while lines that are farther apart indicate smoother terrain.
It would have a very large interval, as the further contour lines are apart, the flatter the terrain, and the great plaines are very flat so..

If the contour lines are far apart, then that indicates the land has a gentle slope (low slope).
If the contour lines are far apart, then that indicates the land has a gentle slope (low slope).
If the contour lines on a topographic map have wide spaces in between and are further apart then the terrain is relatively flat. If the contour lines are close together then the terrain forms a steep slope.
If the topographic lines are closer together it means that it has a steeper slope grade, if they are farther apart, it means that they have a more relaxed slope grade. There is usually a scale on the map that can tell you in exact measurements of the slope.

a gentle slope
Contour lines that are far apart indicate a gentle slope. Because contour lines connect points with the same elevation, wide spacing indicates that the elevation is not changing drastically.
