Submarine canyons are steep, narrow valleys or trenches that occur on the continental shelf and slope of the ocean floor. They are typically characterized by their V-shaped cross-section and can extend from the shore down into deep ocean basins. Submarine canyons are formed primarily by erosion and sediment transport processes, often influenced by powerful forces such as ocean currents, tides, and turbidity currents (underwater flows of sediment-laden water).
