Explanation:

Canyon Definition: Two steep cliffs with a valley running between them. There is often a river that runs through the two.

How are Canyons Formed?
A canyon has to be formed through erosion. There are a couple of ways this erosion occurs. The most common way is look at the Colorado River. The Colorado River carved out the great Grand Canyon by taking the land down the river with it. What was left was a river valley with steep cliffs. This process took thousands of years.

Another way these great landforms can be formed is through wind and glaciers. This is not too common but does happen.

A canyon has 3 main characteristics
Narrow valley
Steep sides
Created by erosion, mainly by rivers.
