What can you infer about the type of erosion that formed the Grand

Canyon?

The main source from erosion at the ground of the canyon would be the water from the stream that is constantly flowing. Another source of erosion would be the wind/air eroding the rocks very slowly over a long period of time. and the more eroded the Canyon is, the more prone to erosion it becomes with more exposed rocks.

Water: Long time. Constantly eroded it.

Wind: Long time. Erosion over time. Takes longer than water.
