WAYS WATER ERODES SOIL
Erosion: Raindrop erosion is caused by the direct
impact of falling drops of rain dislodging soil particles which are
then easily transported by runoff.
Erosion: Sheet erosion is the removal of surface soil
by the action of raindrop splash and runoff as water moves in broad
sheets over the land.
and Gully Erosion: Rill and gully erosion occur when
runoff concentrates in rivulets and creates grooves, called rills, in
the soil surface. With sufficient water flow, rills
may develop into gullies.
