Question
What is Concave Slope and Convex Slope? Explain?
Advertisements
Solution
Concave Slope: The slope is very gentle at the foot and it goes on getting steeper and steeper towards the top. The spacing between successive contours at the lower level is more than at the higher level.

Convex Slope: The slope is very steep at the foot and it goes on becoming gentle towards the top. The contour lines are therefore, unequally spaced but there is a sequence, which is just the opposite of a concave slope diagram. The spacing between successive contours at the lower level is less than at
the higher level.
