Oceans control the Earth’s climate and temperature. They balance heat and are crucial for the creation of rainfall. The 5 oceans of the world have a salinity of roughly 3.5 percent. However, regions like Mediterranean, the Atlantic, and the Bay of Bengal have higher salinity levels.
Pacific Ocean is the world largest ocean, it is ten times bigger than the smallest one, the Arctic Ocean. Interestingly, the smallest ocean in the world is The Arctic Ocean it has 25% of the planet’s undiscovered petroleum resources.
- The Pacific Ocean: The Pacific Ocean is the largest and deepest ocean on this earth. It extends from the Arctic Ocean in the north to the Southern Ocean in the south and is bounded by Asia and Australia in the west and the Americas in the east.
- The Atlantic Ocean: The second largest, extends from the Southern Ocean between the Americas, and Africa and Europe, to the Arctic Ocean. The Atlantic Ocean meets the Indian Ocean south of Africa at Cape Agulhas.
- The Indian Ocean: The third largest, extends northward from the Southern Ocean to India, the Arabian Peninsula, and Southeast Asia in Asia, and between Africa in the west and Australia in the east. The Indian Ocean joins the Pacific Ocean to the east, near Australia.
- The Arctic Ocean: It is the smallest of the five. It joins the Atlantic Ocean near Greenland and Iceland and joins the Pacific Ocean at the Bering Strait. It overlies the North Pole, touching North America in the Western Hemisphere and Scandinavia and Siberia in the Eastern Hemisphere. The Arctic Ocean is partially covered in sea ice, the extent of which varies according to the season.
- The Southern Ocean: It is a proposed ocean surrounding Antarctica, dominated by the Antarctic Circumpolar Current, generally the ocean south of 60 degrees south latitude. The Southern Ocean is partially covered in sea ice, the extent of which varies according to the season.
