Question

sometimes water flows as a sheet over large areas down a slope and washes away the top soil. which type of soil erosion is this?

Answer 1

This type of erosion is known as sheet erosion which is the first step of water erosion. Thus it is further followed by rill and gully erosion...

Answer 2

Answer:

When water flows as a sheet over large areas down a slope and washes away the top soil is called sheet erosion.

Explanation:

Soil Erosion is defined the situation when the soil particles looses or washes away within the valleys, streams, rivers, or lands distant. Due to human activities such as deforestation and agriculture it becomes worse. Erosion is a process that happens either slowly or at an alarming rate.

• Sheet Erosion: Sheet erosion causes noticeable soil loss in both cultivated as well as non-cultivated situations. Although it is being difficult to detect. Sheet erosion happens when a shallow 'sheet' of water flows over the ground surface and causes a uniform layer of soil to be washed away from the surface.

• Rill Erosion: Rill erosion is a type of erosion that produces little streams with distinct boundaries. It happens when rain water  flows across the soil and does not sink into it.
• Gully Erosion: Gully erosion is type of erosion in which removal of soil along drainage lines by surface water run off.
• Splash Erosion: Splash erosion is the initial step of the erosion. It is  also known as raindrop impact. The bombardment of the soil surface by rain drops with high speed causes splash erosion. When rain drops fall on the naked soil, they behave like small bombs, disrupting soil structure and shifting soil particles .
