Answer:
The river has three main courses in its life - the upper coarse, middle coarse and lower coarse

Its erosional activities degrades the land and V-Shaped and I-Shaped valleys can be formed by its erosional activities. I-shaped valleys are formed when the river cuts a valley with steep slopes and V-shaped valleys are formed when the river is still a stream and the vertical erosion is predominant.
Its depositional activities aggrades the land and some of the features caused by its depositional activities are :- Beaches, Oxbow lake (Erosion on concave side and deposition on convex side), and Deltas
