Question

Rill and gully erosion are caused by _____.

A. ice
B. water
C. wind

Answer 1

They are both caused by water.

Answer 2

Gully erosion occurs when runoff water accumulates and rapidly flows in narrow channels during or immediately after heavy rains or melting snow, removing soil to a considerable depth.

Answer 3

Splash erosion is generally seen as the first and least severe stage in the soil erosion process, which is followed by sheet erosion, then rill erosion and finally gully erosion (the most severe of the four).
