An ocean is body of saline water that comprises 72 % of Earth's hydrosphere. The ocean contains 97%, of Earth's water and oceanographers have stated that less than 5% of the world ocean has been explored.
Following are the major oceans, which are arranged in descending order by area :
`text (Pacific Ocean)`
• This ocean is the largest ocean or water body of the world and extended from Arctic Ocean to Antarctic Ocean. The ocean is bounded by Asia and Australia in the West and the South and North America in the East.
• The equator sub-divides the Pacific Ocean into North and South Pacific Ocean. The Marina Trench in the Western-North Pacific is the deepest point in the world (10911 metres).
`text( Atlantic Ocean )`
• This ocean ts second largest of the world's oceans and slightly more than half of the pacific ocean. The ocean occupies an elongated, S-shape basin which extending longitudinally between Eurasia and Africa to the East and South and North America to the West.
• The equatorial counter current sub-divides the ocean into North and South Atlantic Ocean at about 8° North.
`text(Indian Ocean)`
• This ocean is third largest ocean in the world. It is bounded by Asia on the North, Africa on the West, Australia on the East and Antarctica on the South.
• The India ocean contain> approximately 20% of the water on the Earth's surface.
`text( Antarctic Ocean )`
It is the fourth largest ocean in the world. It is also known as Southern Ocean, the South Pole Ocean, is a large body of water encircling the continent of Antarctica. The ocean is particularly covered with ice.
`text( Arctic Ocean )`
It is the smallest and shallowest of the world's five major oceans. It is located mostly in Arctic North Polar region and completely surrounded by Eurasia and North America. The ocean is partly covered by sea ice throughout the year and almost completely in winter.
