The movement of water in the Colorado River had some influence on carving out the Grand Canyon, but scientists believe that water during flash flood coming down tributary canyons ate away a lot of ground. A flash flood in the Grand Canyon amounts to a huge amount of water that has sand, rocks, boulder, and huge boulders being carried downstream with it. A LOT of ground is removed in this way.

Erosion from ice, where water gets into cracks in the ground, then freezes, then expands, pushes a lot of ground and rock away, making the canyon wider and wider.

It is thought that movement of the tectonic plates and the resulting earthquakes, shake a lot of ground and rocks loose.
