What causes undersea canyons?
Over geologic time, submarine canyons are formed by the repeated erosion of the slope by turbidity currents flowing down the canyon axis. Retrogressive slope failures may expand the canyon head, eroding landwards and expanding the size of the canyon.
What is an oceanic Canyon?
Deep-sea canyons are steep-sided valleys cut into the seafloor of the continental slope, sometimes extending well onto the continental shelf.
What do submarine canyons do to waves?
Just as above-sea-level canyons serve as channels for the flow of water across land, submarine canyons serve as channels for the flow of turbidity currents across the seafloor.
What lives in a submarine canyon?

What is difference between Valley and Canyon?
Both canyons and valleys look like deep grooves in the ground surrounded by mountains or cliffs on either sides. In effect, canyons are nothing but deep valleys made by the action of water with steep slopes on either side while valleys are lowland areas between two mountains and have gentler slopes than canyons.
