Question

difference be gully erosion and sheet erosion

Answer 1

YOOOO

WHEN WHOLE LAYER OF SOIL IS ERODED THEN THE PROCESS IS CALLED SHEET EEOSION

IN GULLY EROSION MANY ERODED GULLIES ARE FORMED BUT NOT ALL THE LAYER OF SOIL IS ERODED

Answer 2

Gully erosion is the removal of soil along drainage lines by surface water runoff. Once started, gullies will continue to move by headward erosion or by slumping of the side walls unless steps are taken to stabilise the disturbance

Sheet erosion is the uniform removal of soil in thin layers by the forces of raindrops and overland flow. It can be a very effective erosive process because it can cover large areas of sloping land and go unnoticed for quite some time.

Distinguish between sheet erosion and gully erosion
. Sheet erosion occurs when a thin layer of topsoil is removed. Gully erosion is the process by which gullies are formed. Hillsides are more prone to gullying when they are cleared of vegetation.
