The removal of top soil from a small area of soil surface due to the impact of raindrops is known as
sheet erosion
rill erosion
gully erosion
splash erosion
Explanation
Splash Erosion: Involves the displacement of soil particles caused by the impact of raindrops.
Sheet Erosion: Refers to the removal of thin layers of soil over a large area.
Rill Erosion: Involves the formation of small channels or rills on the surface.
Gully Erosion: Refers to the removal of soil along drainage lines by surface water runoff, creating larger channels.
