Oceans Of The World – What Are These?

These are the five (5) major oceans of the world and brief details about them.

OCEANS OF THE WORLD – The global ocean or ocean alone is composed of five huge oceans connected to each other; here are some things to know about them.

The earth is an ellipsoid of mystery composed mainly of water. It is 71 percent water and the remaining percentage is land. Oceans hold 96.5 percent of all the waters of the Earth. Just amazing how vast and wide that alone right?

There is water in the air as water vapor, in rivers and lakes, in icecaps and glaciers, and in the ground as soil moisture. Even in you and your pet, there’s water.

As stated above, most of the Earth’s water is saline which is the one from the oceans and the world has five major oceans namely the Pacific Ocean, Indian Ocean, Atlantic Ocean, Arctic Ocean, and Southern Ocean.

Here are some details about them:

  • Pacific Ocean

This is the world’s largest body of water. This was named by the Portuguese explorer Ferdinand Magellan who described its water as peaceful and the term peaceful is “pacifique” in French. But contrary to its name, this was actually often slammed by typhoons and hurricanes.

It has an area of 179.7 million km² stretching 15,500 km from the Bering Sea in the Arctic to Antarctica’s Ross Sea in the South. It also contains the deepest point on the Earth known as the Mariana Trench.

  • Indian Ocean

This is the third-largest in the world with a total volume of approximately 292,131,000 km³ (or 70,086,000 mi³). Zambezi, Arvandrud/Shatt-al-Arab, Indus, Ganges, Brahmaputra, and the Irrawaddy are the rivers flowing into this ocean.

  • Atlantic Ocean

The name of the Earth’s second-largest ocean was coined from the “Sea of Atlas” in Greek mythology. Atlantic coasts are marked by bays, gulfs, and seas such as the Caribbean Sea, the Gulf of Mexico, the Gulf of St. Lawrence, the Mediterranean Sea, the Black Sea, the North Sea, the Baltic Sea, and the Norwegian-Greenland Sea. 

Svalbard, Greenland, Iceland, Rockall, Great Britain, Ireland, Fernando de Noronha, the Azores, the Madeira Islands, the Canaries, the Cape Verde Islands, Newfoundland, Bermuda, the West Indies, Ascension, St. Helena, Tristan da Cunha, the Falkland Islands, and South Georgia Island are the islands.

  • Arctic Ocean

This is the world’s smallest and shallowest ocean of all. It is located at the North Pole and its size is just about the size of Russia. The glaciers here have been melting which poses threats because of the rising sea levels.

  • Southern Ocean

The fourth largest ocean has a size of 20,327,000 square kilometers. This is unexplored, has a severe climate, and is far away from the populated areas. In 2021, the International Hydrographic Organization officially recognized this as the fifth major ocean of the Earth.

Meanwhile, 80 percent of the global oceans remained unexplored.
