Sheet erosion occurs when water erodes without being

water often erodes without being in a channel. rainwater that begins to run off during a rainstorm, often flows as thin, broad sheets before forming rills and streams. For ex: wen it rains over an area the rainwater accumulates until it begins moving down a slope as a sheet. Water can also flow as sheets if it breaks out of its channel. floodwaters spilling out of a river can flow as sheets over the surrounding flatland's. streams flowing out of mountains fan out and many flow as sheets away from the foot of the mountain. sheet erosion occurs when water that is flowing as sheets picks up and carries away sediments.
