Question

ivers shape the very landscapes in which we live. When a river does this, what do we call it?

Answer 1

It is called weathering or erosion.

The flowing water of a river has the power to carve and shape the landscape. Many landforms have been sculpted by rivers over time. For example, the Grand Canyon in Arizona in the United States.

When the river flows downwards with a lot of force in the mountainous regions it tears away rocks and soil along its bed and carries them downstream. It carves a narrow, V-shaped valley. Rapids and waterfalls are formed near the sources of rivers.

Deltas are formed where the river meets the ocean because of the huge amount of sediment deposited by the river.
