Question

Why are there valleys and gorges along rivers?​

Answer 1

Answer:

High in the mountains, the river is narrow and fast-flowing. Sometimes, instead of forming a V-shaped valley, rivers create dramatic, steep-sided gorges. ... This happens when the river is running down a landscape that is slowly being pushed upward by plates moving under the Earth's surface.

Answer 2

Answer:

The movement of rivers help in creating the valleys and gorges along the rivers.
