Which of the following is the LEAST visible form of land erosion?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Sheet erosion
- Sheet erosion is the least visible form of land erosion. It is less noticeable, as it does not leave obvious cuts in the soil surface as with gully erosion. It is the removal of a relatively uniform, although thin, layer of soil from the land surface by unchanneled runoff, or sheet flow.
- Sheet erosion takes place on level lands after a heavy shower and the soil removal is not easily noticeable. But it is harmful since it removes the finer and more fertile top soil.
