The sea floor

The sea floor

This diagram shows the depths of different regions of the sea floor. The continental shelf is the relatively shallow seabed that extends from the coast. The continental slope is the steeply descending seabed between the continental shelf and the deep sea floor. Submarine canyons may cut through the slope. The deep sea floor is an extensive plain, at a depth of around 4 kilometres, which contains deep trenches and elevated areas known as seamounts.
