Which are the 3 stages of long profile of a river?

Answer 1

A river profile includes being steeper near the source, where there is a lot more material for the river to cut through before reaching the base level. As the water goes further down the river, the river begins to cut laterally.

Answer 2

The cross profile of a river(sometimes called a cross-section) shows how the river looks at certain points (like the upper stage or middle stage etc). The cross profile of the upper course of a river looks like a V shape. It can help you see if erosion or deposition is occurring in the part of the river you are looking at.

This webpage www.s-cool.co.UK/gcse/geography/rivers/river-profiles.HTML explains it and has a diagram. Just scroll down to Cross Profile.

The profile of the river and valley from one side to another, as if the river has been cut in half like an orange

It is the part of the river simply where the two valley's meet.

Answer 3

The long profile of a river is general information about it like for e.g. middle course, length, altitude, end course etc. you also get information on the gradient.

Answer 4

the upper (youthful) section [close to the source], the middle (mature) section [in the middle of the river], and the lower (senile) section [closer to the mouth of the river.

Answer 5

the long profile of a river is the line follow by a river from it source in the highland to it mouth in the sea
