GEOLOGY

Detailed explanation-1: -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. Even though they are underwater, continental shelves are part of the continent.

Detailed explanation-2: -The continental shelf is the gently sloping submerged surface extending from the shoreline.

Detailed explanation-3: -The term “continental shelf” is used by geologists generally to mean that part of the continental margin which is between the shoreline and the shelf break or, where there is no noticeable slope, between the shoreline and the point where the depth of the superjacent water is approximately between 100 and 200 metres.

Detailed explanation-4: -A continental rise is the gently sloping surface at the base of the continental slope.
