The continental margin's bathymetric zones, from shallowest to deepest, proceed from the continental shelf (a gently sloping, shallow platform extending from the coast), to the continental slope (a much steeper region where the seafloor drops more rapidly toward oceanic depths), to the continental rise (a gently sloping accumulation of sediment at the base of the continental slope, transitioning into the abyssal plain), representing progressively increasing water depth.
The continental shelf is the shallowest of the three zones, a nearly flat, gently sloping submerged extension of the continent, typically extending to depths of...
