Ocean Part 2

When you look at a globe, you will see that there is actually one big world Ocean. But to make the study of Oceans easy, we have divided the oceans in to 5 Major oceans briefly using the continents as the boundary.

1. Pacific Ocean. Covers 46% of the earth.
2. Atlantic Ocean. Covers 23% of the earth.
3. Indian Ocean. Covers 21% of the earth.
4. Arctic Ocean. 4% of the earth.
5. Southern Ocean. 6% of the earth.

When an area of Ocean partly enclosed by land it is called a sea.

2/3 of the earth's land mass is in the Northern Hemisphere and because of that 80 % of the Ocean is in the Southern Hemishphere.

Pacific Ocean

Pacific Ocean is the largest and the deepest Ocean. In order to understand how huge Pacific Ocean is, imagine putting together all the land mass on earth, Pacific Ocean will still be larger than that.

Ferdinand Magellan named the Pacific Ocean after the Latin word Mare Pacificum meaning Peaceful sea. It extends from the Arctic in the north to Antartica in the south, bounded by Asia and Australia in the west, and the Americas in the east.

Mariana Trench, the lowest point in the Earth's crust ( 10911 meters below sea level) is in the Pacific Ocean.
