erosion
Erosion and weathering: Glaciers form 'U'-shaped valleys, while rivers form 'V'-shaped valleys.
Pre Deposition is formed by erosion, cliff, aches, and beaches.
Canyons are formed by erosion. Rivers that were previously located there slowly wear down rock and form large canyons in the rock.
Valleys, Mountains, and Rivers, occasionally volcanoes... ~:)

The formation of the Grand Canyon was accomplished by the constant erosion of the rock by the Colorado River over some 17 million years. Over time the river was able to carve a very deep channel into the Colorado Plateau. Links are provided to specifics regarding the geology of the Grand Canyon.

There are only a few types of canyons. These are river canyons, mountain canyons, and canyons that were formed by weathering and erosion. +++ Very few types indeed. One in fact! All canyons are formed by weathering & erosion; and all are or were river canyons irrespective of mountains. The requirements for a canyon or gorge to form are a high plateau catchment area feeding a large river for sufficiently long for it to cut back from a steep rim.
water erodes a canyon by carrying sediment from the rock walls down the river
