                               OCEAN

There are five types of the ocean. In the order of their size, they are the Pacific ocean, Atlantic ocean, Indian ocean, Arctic ocean, and Southern ocean. The average depth of an ocean is 4 km.

(1) Pacific ocean:- It is the largest and deepest ocean. most of the islands are the coral origin of volcanic. The marina trench is the deepest trench in the world with a depth of 11033 km is in the Pacific ocean.

(2) Atlantic ocean:- It has the longest coastline in the world. It is the busiest ocean for trade and commerce since its sea routes connect the two industrialized regions, namely Western Europe and the Northern-Eastern United state of America. The Atlantic ocean is still widening. Puerto Rico is the deepest trench in this ocean.

(3) Indian ocean:- Only ocean named after a country. It is deeper than the Atlantic ocean. Here the number of continental islands is more than that of volcanic islands. Sunda (earlier known as java) trench is deepest in this ocean.

(4) Arctic ocean:- It is the smallest ocean and lies within the Arctic circle. The north pole lies in the middle of the Arctic ocean. Most of the parts of the ocean are frozen and hence least saline and the shallowest among all the oceans. Nansel Trench is the deepest trench point of this ocean.

(5) Southern Ocean:- It is situated in the southern part of the earth and some parts of this ocean are frozen and are bigger than the Arctic ocean. The sandwich trench is the deepest trench in this Southern ocean.
