Question

How are oceans divided?

Answer 1

Oceans:

1. The ocean consists of a large area of salt water.
2. Oceans hold about 97% of the world's water.
3. There are totally 5 oceans in the world that cover about 70% of the entire Earth's surface.
4. There are five oceans in the world.
5. They are divided into four divisions.

Division of oceans:

In general, the ocean floor can be divided into four major divisions: a. continental shelf, b. continental slope, c. continental rise, d. abyssal plain.

A. Continental Shelf:

1. The continental shelf is the shallow part of the ocean that lies close to the continental margin.
2. It is actually a part of the continent sloping slowly towards sea level.

B. Continental Slope:

1. The continental slope is beyond the continental shelf, where the sea level slopes downward.
2. The steep-sided continental slope separates the continental shelf from the deep ocean floor.

C. Continental Rise:

1. The Continental slope is the gradually sloping area at the end of the continental slope.
2. The mean gradient of this region does not exceed one degree.

D. Abyssal Plain:

1. At the end of the continental slope and uplift, the deepest part of the ocean is the Abyss Plain.
2. It is completely plain and covered with sediments of terrestrial and shallow water origin.
