5 Oceans of the World

5 Oceans of the World


The surface of Planet Earth is around 70% water, over 96% of which is salt water. While this vast area is mostly interconnected, it is broken up into large and small bodies by the seven continents and other landmasses. The largest of these bodies are known as the Great Oceans.

The World Ocean or global ocean is a term used to define all the world's oceans as one big ocean.

It is divided into five oceans. These divisions are the( According to The Size): 

1- Pacific Ocean,

2- Atlantic Ocean,

3- Indian Ocean, 

4- Southern Ocean,

5- Arctic Ocean.

Pacific Ocean:

The Pacific Ocean, the biggest of all, also reaches northward from the Southern Ocean to the Arctic Ocean. It is in the gap between Australia, Asia, North America and Oceania. The Pacific Ocean meets the Atlantic south of South America at Cape Horn.

The Pacific Ocean is the body of water between Asia and Australia in the west, the Americas in the east, the Southern Ocean to the south, and the Arctic Ocean to the north.
The Pacific is the largest of these oceans, covering 63,784,077 sq miles (165,200,000 km²).

The Pacific was named by Portuguese explorer Ferdinand Magellan, who set sail from Spain in 1519 to find a westerly route to the Spice Islands around the southernmost tip of South America. Rounding the Horn for the first time in November 1520, Magellan passed through the Straits now named for him into a vast sea so calm he described it as a “beautiful, peaceful [Pacific] ocean.” 

Atlantic Ocean:


The Atlantic Ocean, the second biggest, extends from the Southern Ocean between South America, Africa, North America and Europe, to the Arctic Ocean. The Atlantic meets the Indian Ocean south of Africa at Cape Agulhas. 

Its Area is 41,081,270 sq miles (106,400,000 km²). It includes the Mediterranean, Caribbean and Baltic Seas, and the Gulf of Mexico.

The average depth of the Atlantic, along with its adjacent seas, is 3,339 meters.

The greatest depth is Milwaukee Deep near Puerto Rico, where the Ocean is 8,380 metres (4,580 fathoms; 27,490 ft) deep.

Indian Ocean:

The Indian Ocean is Third Biggest Ocean in the world.The Indian Ocean extends northward from the Southern Ocean to India, between Africa and Australia. The Indian Ocean joins the Pacific Ocean to the west, near Australia.

"Home to a great variety of humankind throughout history, the Indian Ocean is also rich in exotic plant and animal species, and still supplies the world with spices such as black pepper, nutmeg, and ginger. While these spices are now used primarily to flavor the world’s cuisines, they were used from earliest times to preserve foods, and were thought to have great medicinal properties.during the terrible plagues of the 13th through 17th Centuries, Europeans were so convinced of their curative powers that their countries fought repeated wars and gambled untold fortunes to gain control of the Spice Islands, and the number of explorers and sailors willing to risk their lives charting new maps to reach them is difficult to imagine."

The deepest point in the Indian Ocean is in the Java Trench near the Sunda Islands in the east, 7500 m (25,344 feet) deep. The average depth is 13,002 feet deep

The Indian Ocean is the third largest ocean, 28,350,000 square miles in size. The majority is in the southern hemisphere.

Southern Ocean:

5 Oceans of the World

Until the mid-20th Century, the waters surrounding Antarctica were generally considered to be extensions of the adjoining oceans. But in 2000, members of the International Hydrographic Organization almost unanimously agreed to identify these southernmost waters as the Southern Ocean. 

Although its definite boundaries are yet to be determined, below 60°S latitude is generally accepted, giving it an area of 7,848,299 sq miles (20,327,000 km²), and making it the fourth largest of the Earth’s oceans. Joining waters of the southern Pacific, Atlantic and Indian Oceans with a persistent easterly current, the frigid Southern Ocean has a great influence on the Earth’s weather patterns.

Arctic Ocean:


5 Oceans of the World

The Arctic is the smallest and shallowest of the five Oceans and falls mostly within the Arctic Circle. The Arctic Ocean is the ocean around the North Pole. The most northern parts of Eurasia and North America are around the Arctic Ocean. 

For most of the year, these seas are a mass of ice often hundreds of feet thick; even during the brief summer months ice can make the Arctic Ocean impassable, and it wasn’t known until modern times that there is little solid ground in the most northern reaches of the Earth. 

The ocean's area is about 14.056 million km2, which is the smallest of the world's 5 oceans, and it has 45,389 kilometres (28,203 miles) of coastline. 

The average depth of the Arctic Ocean is 1,038 metres (3,406 feet).[1] The deepest point is in the Eurasian Basin, at 5,450 m (17,881 ft).
