Question

discuss one feature each of the three courses of the river

Answer 1

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 has a rapid, tumbling flow that cuts a narrow channel through rocky hills or 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 of a river’s journey, when it gets wider and slows down, is called the middle age.

Rivers often 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 riverbed, where it forms bars of sand or gravel or builds islands.

Old River - the lower course

When the river reaches the end of its 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.

The photograph below show the sediment (mud) that the Darent has brought with it on its journey to the River Thames.

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

1) youthful stage :-

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

2) 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.

3) 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 forming deltas and at this stage river meets to ocean
