Geography of the Ocean and the Structure of Planet Ocean. The Global Ocean The five oceans from smallest to largest are: the Arctic, Southern, Indian, Atlantic and Pacific. These five "oceans" are connected and are actually one huge body of water, called the global ocean or just the ocean. If you were to add the smaller seas like the Barents, Beaufort, Chukchi, Kara, Laptev, East Siberian, Lincoln, Wandel, Greenland and Norwegian, etc. you would have a total area of the ocean of about 361,000,000 km² (which is ~71% of the Earth's surface), a total volume of roughly 1,370,000,000 km³, and an average depth of 3,790 m. The word “Ocean” comes from Okeanos , the Greek god of the Ocean. Terrigenous , pelagic , and authigenic materials composes most of ocean sediments.

And globigerina , pteropod and siliceous oozes . M deep, but they are thickest in convergence belts and upwelling zones. And phillipsite and can be found in places where the sedimentation process occurs very slowly or currents sort out the deposits. The Arctic Ocean into the 4,000-4,500 . . M. . Km. Deepest Part of the Ocean - Deepest Ocean Trench. Home » Records » Deepest Point in the Oceans The Challenger Deep in the Mariana Trench is the deepest known location in Earth's oceans. Mariana Trench map: Map showing the geographic location of the Mariana Trench in the Pacific Ocean. Image from the CIA Factbook. Measuring the Greatest Ocean Depth 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. If Mount Everest, the highest mountain on Earth, were placed at this location it would be covered by over one mile of water. The first depth measurements in the Mariana Trench were made by the British survey ship HMS Challenger, which was used by the Royal Navy in 1875 to conduct research in the trench.

Great Barrier Reef | Australia's Great Natural Wonder. 10 Must-See Places In Your Lifetime - the Brofessional. History of the Ocean. When the Earth formed about 4.5 billion years ago... The ocean is not just where the land happens to be covered by water. The sea floor is geologically distinct from the continents. It is locked in a perpetual cycle of birth and destruction that shapes the ocean and controls much of the geology and geological history of the continents. Geological processes that occur beneath the waters of the sea affect not only marine life, but dry land as well. .

The presence of large amounts of liquid water makes our planet unique. Our ocean covers 72% of the earth's surface. The ocean is traditionally classified into four large basins. Though we usually treat the oceans as four separate entities, they are actually interconnected. The earth and the rest of the solar system are thought to have originated about 4.5 billion years ago from a cloud or clouds of dust. So much heat was produced as the early earth formed that the planet was probably molten. . , obtained samples of the actual sea floor rock.

The ocean covers 70 percent of the Earth's surface. It contains about 1.35 billion cubic kilometers (324 million cubic miles) of water, which is about 97 percent of all the water on Earth.

The ocean makes all life on Earth possible, and makes the planet appear blue when viewed from space. Earth is the only planet in our solar system that is definitely known to contain liquid water. Although the ocean is one continuous body of water, oceanographers have divided it into four principal areas: the Pacific, Atlantic, Indian, and Arctic Oceans. Climate The ocean plays a vital role in climate and weather. The atmosphere receives much of its heat from the ocean. Because water absorbs and loses heat more slowly than land masses, the ocean helps balance global temperatures by absorbing heat in the summer and releasing it in the winter. Ocean Formation After the Earth began to form about 4.6 billion years ago, it gradually separated into layers of lighter and heavier rock. Ocean Floor Fishing.
