geomorphological formation as narrow and deep ravine between cliffs

A canyon (or gorge) is a big crack in the ground, or a very deep valley.[1] Most canyons are made by rivers. A few are made by earthquakes. They can be big, like the Grand Canyon, or small.

Canyons can be formed by erosion by running water which will take rocks and soil away.
