Canyon formation is common in arid and semi-arid climates because bedrock weathers slowly in the absence of water . Therefore, canyon-forming streams are able to cut vertically much more rapidly than their valleys can be widened by mass wasting or other erosional processes. A canyon eroded into relatively uniform ...
