Five Oceans of the World

The world oceans have been divided into five categories: 

1. Pacific Ocean – Is spread across Asia and Americas and home to Mariana Trench, the Earth’s deepest point. 
2. Atlantic Ocean – Atlantic Ocean, the second largest ocean, connects Europe, Americas, playing an important role in climate and world commerce. 
3. The Indian Ocean – lies between Africa, Asia and Australia and is known for its monsoon and warm waters.
4. Arctic Ocean – Surrounds the north pole and is the shallowest and smallest ocean.
5. Southern Ocean – Encircling Antarctica, it plays a critical role in driving global ocean currents and is now officially recognised by the International Hydrographic Organisation.

These five oceans collectively regulate climate, transport heat via ocean currents, and support countless marine ecosystems.
