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: -Continental shelf is an extension of the land near the coast that is actually submerged under the ocean. It is also known as the submerged coastland.
Detailed explanation-3: -A continental shelf is a portion of a continent that is submerged under an area of relatively shallow water, known as a shelf sea.
Detailed explanation-4: -The oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf (such as the Neritic zone), but operationally is often referred to as beginning where the water depths drop to below 200 meters (660 feet), seaward from the coast into the open ocean with its Pelagic zone.
