Question

Sometime the river start erosion upstream this happens when the head stream gets a lot of water in the early stages of rivers flow identify the correct option a) down cutting b)headward erosion c)lateral erosion d) vertical erosion

Answer 1

Explanation:

its because of lateral errosion

Answer 2

Answer:

Option (B)

Explanation:

The Headward erosion is defined as an fluvial erosional process where the origin of the river is being eroded by the river, thereby resulting in the increasing length of the river and leads to the formation of a larger type of drainage basin (catchment area). Here, the water flowing over a planer surface has a tendency to move along the slope mostly forming an oscillating type of stream. If this type of erosion takes place for a longer period of time then it can split the river channel into an adjacent catchment basin.

Thus, the correct answer is option (B).
