OCEANS AND SEAS OF THE WORLD

· An ocean is a body of saline water that composes much of a planet's hydrosphere.

· On Earth, an ocean is one of the major conventional divisions of the World Ocean, which covers almost 71% of its surface.

· These are, in descending order by area, the Pacific, Atlantic, Indian, Southern, and Arctic Oceans.

· The word sea is often used interchangeably with "ocean" in American English but, strictly speaking, a sea is a body of saline water (generally a division of the world ocean) partly or fully enclosed by land.

Ocean	Location	Area(km2)	Avg. Depth (m)	Deepest Point
Pacific Ocean	Separates Asia and Oceania from the Americas	168,723,000 (46.6%)	3,970	Mariana Trench* (36,070 ft)
Indian Ocean	Washes upon southern Asia and separates Africa and Australia	70,560,000 (19.5%)	3,741	Sunda Trench or Java Trench (25,344 ft)
Atlantic Ocean	Separates the Americas from Eurasia and Africa	85,133,000 (23.5%)	3,646	Puerto Rico Trench (28,232 ft)
Southern Ocean	Sometimes considered an extension of the Pacific, Atlantic and Indian Oceans, which encircles Antarctica	21,960,000 (6.1%)	3,270	South Sandwich Trench (23,740 ft)
Arctic Ocean	Sometimes considered a sea or estuary of the Atlantic, which covers much of the Arctic and washes upon northern North America and Eurasia	15,558,000 (4.3%)	1,205	Litke Deep in the Eurasian Basin (17,880 ft)

*The Challenger Deep in the Mariana Trench is the deepest known point in Earth's oceans. In 2010 the United States Center for Coastal & Ocean Mapping measured the depth of the Challenger Deep at 10,994 meters (36,070 feet) below sea level with an estimated vertical accuracy of ± 40 meters.

Major Seas Around The World

· A sea is a large body of salt water that is surrounded in whole or in part by land.

· More broadly, "the sea" is the interconnected system of Earth's salty, oceanic waters, considered as one global ocean or as several principal oceanic divisions.

· The sea moderates Earth's climate and has important roles in the water cycle, carbon cycle, and nitrogen cycle
