Question

what is meant by steep and gentle slopes

Answer 1

It is the roughness of the roads

Answer 2

Slopes are known as the rise or fall of a terrain feature. The speed at which something can move is affected by the slope of the terrain feature. Further determination of the slope is done by looking at the contour lines.

GENTLE SLOPES: In gentle slopes the contour lines are evenly spaced and wide apart indicating a uniform gentle slope.

STEEP SLOPES:  In steep slopes the contour lines are evenly spaced but close together. So the closer the contour lines, the steeper will be the slope.
