All oceans of the world are connected to each other. There are four main oceans. In order of their size, They are – Pacific Ocean, Atlantic Ocean, Indian Ocean, and, Arctic Ocean. Many geographers regard the area around the Antarctica continent as the Antarctic Ocean, but most scientists are of the view that this portion of the Earth has no natural boundaries to the south.
Oceans of the World #1
Pacific Ocean
- It is the largest and the deepest ocean in the world. It is oval.
- It is bounded by North America and South America in the east and Asia and Australia in the west.
- The Pacific Ocean has a much shorter and regular coastline and has fewer harbours than the Atlantic Ocean.
- Because its shores are not bordered by very fertile and commercial lands, it is commercially less important than the Atlantic Ocean.
- The Mariana Trench, the deepest known point on the Earth’s surface, is located in the Pacific Ocean.
Oceans of the World #2
Atlantic Ocean
- It is the second largest ocean in the world. It is an S-shaped ocean.
- The Central Ridge runs almost in the middle of the Ocean. It is on this ridge (a ridge is a geological feature which consists of a chain of mountains or hills running for a considerable distance) that most islands of the Atlantic Ocean lie.
- The coastline of the Atlantic Ocean is broken and is bordered by many fertile lands of Europe.
- The Atlantic Ocean is the biggest highway of commerce.
Oceans of the World #3
Indian Ocean
- It is the third largest ocean in the world. It is the only ocean which is named after a country (India).
- It is surrounded by the Indian subcontinent in the north, East Africa on the west and Indo China in the east.
- Sunda Trench is the deepest point in the Indian Ocean.
- After the construction of the Suez Canal (connecting the Indian Ocean with the Mediterranean Sea), its commercial importance has increased.
Oceans of the World #4
Arctic Ocean
- It is located near the North Pole and mostly remains frozen.
- It is connected to the Atlantic Ocean by the eastern and western Greenland channels and the Pacific Ocean by the Bering Strait.
- Many scientists contend that it cannot be regarded as an ocean as it is not navigable. This is because it freezes completely during winters. However, its separate existence and its area spreading over 13 million sq km entitle it to be called an ocean.
Oceans of the World #5
Antarctic Ocean
Many geographers regard the area around the Antarctica continent as the Antarctic Ocean, but most scientists are of the view that this portion of the Earth has no natural boundaries to the south. It consists of the southern portions of the Pacific, Atlantic, and Indian oceans. It is thus also known as the Southern Sea.
