The movement of rivers, the processes of weathering and erosion, and tectonic activity create canyons. The most familiar type of canyon is probably the river canyon. The water pressure of a river can cut deep into a river bed. Sediments from the river bed are carried downstream, creating a deep, narrow channel. Hope this helps! ^-^ If it does, plz mark me as brainiest and thank me!
