While submarine canyons can cut across continental shelves, they are more characteristic features of continental slopes, not the shelf itself as a defining characteristic.

Continental shelves are gently sloping underwater extensions of continents, known for shallow depths and abundant marine life.

Continental shelves are important for fishing grounds due to their biological productivity and are significant sources of oil and gas reserves. They also accumulate large amounts of sediment, forming stores of sand and gravel. Submarine canyons are steep-sided valleys cut into the seabed.
