GENERAL GEOLOGY

Detailed explanation-1: -Two major regions of the ocean floor are the continental margin and the deep-ocean basin. The continental margin is the region of ocean floor closest to land, and it is basically a section of continent with ocean water covering it.

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. Even though they are underwater, continental shelves are part of the continent.

Detailed explanation-3: -The seabed (also known as the seafloor, sea floor, ocean floor, and ocean bottom) is the bottom of the ocean. All floors of the ocean are known as ‘seabeds’.

Detailed explanation-4: -A seamount is an underwater mountain formed by volcanic activity.
