5 Oceans of the World

Approximately 72% of the Earth is covered with water, of which 71% is owing to the oceans. The bluish color is because of organic elements in water and the presence of chlorophyll.

Ocean Facts and Information

An ocean is a large body of saline water teeming with plant and animal life. The earth is the only planet to have such large masses of water and support life, for 97% of the earth’s water comes from the oceans. Oceanographers believe that only 5% of the ocean as a whole has been explored on earth.

How many Oceans in the World?

There are five oceans of the world – the Pacific, the Antarctic, the Atlantic, the Arctic and the Indian. The Pacific is the largest ocean in the world. (Try to include a map of the Pacific Ocean as that is searched for) Continents have been divided majorly by the world oceans. For instance, the Pacific Ocean separates Asia and Oceania from the Americas.

The Atlantic separates the Americas from Eurasia and Africa. The Southern Ocean or the Antarctic Ocean encircles the continent of Antartica and the Arctic Ocean covers much of the Arctic and reaches North America and Eurasia.

Oceans and Climate

The oceans are responsible for regulating the climate of the earth as well. They transfer the heat from the hotter regions (called tropics) to the colder regions (called the polar regions). Due to the enormity of the oceans, the influence of the oceans on the climate increases.

Life within the ocean evolved 3 billion years prior to the life on land.

Oceans are of great economic importance to us as they make trade possible.
