A canyon is a deep valley with steep sides often carved by a river or glacial activity, while a mountain is a landform that rises prominently above its surroundings with a peak or summit. Canyons are typically formed through erosion, while mountains are generally created through tectonic processes such as uplift and volcanic activity.
