Answer:
C. Runoff from heavy rainfall forms narrow, shallow channels.
Explanation:
Erosion is the gradual washing away of the top layer of the soil or earth on which plant grows. There are three main types of erosion which are:
1. Sheet erosion
2. Gully erosion
3. Rill erosion
Rill erosion occurs when a soil layer is gradually being washed away by narrow stream channels called streamlets on the surface. After a heavy downpour, the streamlets facilitates the movement of water on the ground surface and in turn, earth materials are worn away.
When these streamlets becomes deeper, they form gullies. Gullies results into gully erosion.
When runoff removes soil and loose sediment in thin layers it is called sheet erosion.
