Answer:
The correct answer is option C, a rushing river
Step-by-step explanation:
Canyons are formed as of the erosional activities of both wind and water affecting a huge plateau, mountain or hill. These plateaus, mountains, and hills are formed due to tectonic movements.
During the course of time, snow on the plateau melts and pull down half a million tons of sediments along with it. This sediment carrying river cuts the plateau thereby forming the Canyons
