Introduction

The world or global ocean is a large body of salt water that covers the earth. It is divided into 5 oceans — Pacific Ocean, Atlantic Ocean, Indian Ocean, Arctic Ocean and Southern Ocean (Antarctica).

Oceans cover more than 70% of the Earth's surface.

List of Oceans

Here is a list of the five oceans:

Arctic Ocean: The world's smallest ocean. It is also the coldest.

Atlantic Ocean: Ocean between North and South America and the European and African continents. It is the saltiest ocean.

Indian Ocean: Lies between Africa, Asia, Australia, and the Southern Ocean.

Pacific Ocean: The World's largest ocean. It covers more than 30% of the Earth.

Southern Ocean: Completely surrounds Antarctica.
