the three stages of a river are- the upper course or the mountain stage- in this stage the river undergoes the mountains that are really very steep so the river has freat cutting power in this stage. the main work of the river in this stage is erosion and transportation. the middle course or the plain stage- the ground becomes less flat and the river slows down. the river becomes very smooth , but still it erodes some of the rocks. in the end of the middle stage , deposition takes place. the lower course or the delta stage- in this stage, the river slows down completely and forms a delta. ........well if useful mark it BRAINLIEST

Upper course — At this stage, the river flows swiftly, for the gradients are steep. This course generally lies in a hilly area and the river flows a considerable distance over a steep slope.
Middle course — At this stage, the gradient is reduced, and the river flows more slowly. In the middle course of the river, the energy required to transport the materials is just enough to drag large particles.
Lower course — In this stage, the rover flows sluggishly and makes many landforms. All the ideal conditions for depositional landforms exist but the load-transporting capacity is drastically reduced due to the sluggish flow as well as division of a river into many distributaries.
