Indian Ocean

The Indian Ocean is the third largest ocean in the world after the Pacific Ocean and the Atlantic Ocean. It covers approximately 14% of the Earth’s surface and about 20% of the water on the Earth’s surface. It is also the warmest ocean in the world. Its temperature makes it difficult for Phytoplankton to grow and live in.

It has low oxygen content and that is also a big reason for limited sea life. During the 1500s, the ocean was explored by sailors to find a route around Africa. According to an estimate, approximately 40% of the world’s oil comes from the Indian Ocean.
