Which of the following is NOT a part of the ocean floor?

Correct option is C

The correct answer is (c) The deep sea shelf.
· The ocean floor consists of several distinct features, each playing a key role in the structure of the seabed.
· However, there is no feature called the deep sea shelf in the accepted terminology of oceanography.
Instead, the ocean floor includes the following parts:
1. The continental shelf: This is the submerged portion of the continent that gently slopes towards the deep ocean. It is a relatively shallow area compared to the open ocean, typically extending from the coastline to depths of around 200 meters.
2. The continental slope: This is the steep slope that descends from the edge of the continental shelf to the ocean basin. It marks the boundary between the continental crust and the oceanic crust.
3. The deep sea plain (also known as the abyssal plain): These are vast, flat regions of the ocean floor, typically found at depths of around 3,000 to 5,000 meters. They are covered with fine sediments and are located beyond the continental slope.
Additional Information:
· The ocean floor includes other features as well, such as ocean ridges, trenches, seamounts, and guyots.
· The continental shelf and continental slope are part of the continental margin, which is the underwater extension of the continent.
