A submarine canyon is a steep-sided valley cut into the seabed of the continental slope, sometimes extending onto the continental shelf, with nearly vertical walls that can rise as much as five kilometers from canyon floor to rim. Submarine canyons act as channels for turbidity currents, dense sediment-laden flows supplied by rivers or triggered by storms, submarine landslides and earthquakes, which travel downslope at great speed, eroding the slope before depositing sediment onto the abyssal plain.

A submarine canyon is a steep-sided valley cut into the seabed of the continental slope, sometimes extending well onto the continental shelf, having nearly vertical walls, and occasionally having canyon wall heights of up to 5 km (3 mi), from canyon floor to canyon rim, as with the Great Bahama Cany
Caused By: Erosion, Lead
The formation of submarine canyons is believed to occur as the result of at least two main process: 1) erosion by turbidity current erosion; and 2) slumping and mass wasting of the continental slope.
