Here's why:

* Canyons are deep, narrow valleys formed primarily by the erosive power of rivers over long periods.

* Wind can also play a role in shaping canyons by eroding the rock walls and creating unique features like hoodoos and arches.

While other landforms like ravines and gorges can also be carved by water, they are generally smaller and less dramatic than canyons.
