Question

name the work of river diagram​

Answer 1

Answer:

There are three main types of processes that occur in a river. These are erosion, transportation and deposition. All three depend on the amount of energy there is in a river.

Types of erosion

The energy in a river causes erosion. The bed and banks can be eroded making it wider, deeper and longer.

Headward erosion makes a river longer. This erosion happens near its source. Surface run-off and throughflow cause erosion at the point where the water enters the valley head.

Vertical erosion makes a river channel deeper. This happens more in the upper stages of a river (the V of vertical erosion should help you remember the V-shaped valleys that are created in the upper stages).

Lateral erosion makes a river wider. This occurs mostly in the middle and lower stages of a river.

There are four main processes of erosion that occur in rivers. These are:

hydraulic action;

abrasion / corrasion;

attrition; and

corrosion.
