The seafloor can be divided into different levels extending from the edges of the continents to the deep ocean floor:
The continental shelf extends seaward from the shore and is the shallowest part of the continental margin.
The continental slope is the area of the seafloor just beyond the continental shelf, where the slope of the seafloor becomes steeper.
The continental rise extends beyond the steep continental slope. It is more gently sloping and is composed of the sediments deposited by turbidity currents at the base of the continental slope.
