WebHow the Continental Rise Forms There are couple ways all those sediments wind up at the continental rise. A lot of sediments come through the submarine canyons and merge … Deposition of sediments at the mouth of submarine canyons may form enormous fan-shaped accumulations called submarine fans on both the continental slope and continental rise. Alluvial or sedimentary fans are shallow cone-shaped reliefs at the base of the continental slope that merge together, forming the continental rise. Erosional submarine canyons slope downward and lead to alluvial fan valleys with increasing depth. It is in this zone that sediment is deposited, forming th… scuttle used in a sentence https://dpnutritionandfitness.com
