GEOLOGY

Detailed explanation-1: -At the edge of the shelf, the ocean floor drops off in a steep incline called the continental slope (A).

Detailed explanation-2: -A continental shelf extends from the coastline of a continent to a drop-off point called the shelf break. From the break, the shelf descends toward the deep ocean floor in what is called the continental slope.

Detailed explanation-3: -Continental slope – The slope is “the deepening sea floor out from the shelf edge to the upper limit of the continental rise, or the point where there is a general decrease in steepness” (IHO, 2008).

Detailed explanation-4: -The CONTINENTAL MARGIN is the transition to the deep ocean basin. The margin belongs mostly to the continent. The CONTINENTAL SLOPE, as its name implies, is the sloping edge of the continent as it merges into the deep ocean basin.
