Briefly describe how submarine canyons are created
What will be an ideal response?
Submarine canyons are narrow but deep v-shaped valleys resembling canyons on land that occur on the edges of continental shelves and rises. Although it was initially thought that submarine canyons were created by river erosion when sea level was lower, the majority of canyons are deeper (3,500 meters) and were never exposed. Instead, both direct and indirect observations suggest that turbidity currents are responsible for carving submarine canyons, in which sediments on the continental shelf accumulate and flow rapidly, especially after a seismic event, down the continental rise.
