Question

Discuss one feature is of the three course of the river.​

Answer 1

Answer:

What are a river's three stages?

Nearly all rivers have an upper, middle and lower course.

Young River - the upper course

The beginning of a river, when it flows quickly with lots of energy is called a young river.

The river here is smaller and usually had a rapid, tumbling flow that cuts a narrow channel through Rocky hills and mountains.

The fast flowing river can create waterfalls where it carves out layers of soft rock and leaves a cliff of hard rock standing.

Middle aged river - the middle course

The middle course of a river's journey, when it gets wider and slow down is called the middle age.

Rivers of ten meander (follow a winding path) along their middle course

The current of the river no longer has the force to carry stones or gravel. This material drops to the river bed, where it forms bars of sand or gravel or builds islands.

Old river - the lower course

When the river reaches the ends of it journey, it is called an old river. The end of the river is called the mouth.

At the mouth there is often a river delta, a large, silty area where the river splits into many different slow flowing channels that have muddy banks.

Originally answered :what are the different stages of a river?

There are three stages of river

1. Youthful stage
2. Mature stage
3. Old stage

Youthful stage:-

At this stage river is in its erosional phase, we can see deep gorge, V-shaped valley, canyon, potholes. At this phase the erosional possesses are more predominant.

Mature stage :-

When river goes into the gentle sloppy region, that time there are both of the things (erosional, Depositional) processes are same at this stage river starts meandering.

Old stage :-

The old stage come when river goes into very gentle sloppy region, where slop is near 0 degree, that time river is more predominant in Depositional process, it starts farming deltas and at the stage river meets to ocean.
