The Geology of the Ocean Basins Oceanic basins can be close to land, starting at a continents edge and moving inward towards deeper water, but geologically speaking, basins are any part of the ocean below sea level. Ocean basins are usually denoted as beginning once you reach the oceanic trench which physically seperates the continent from the ocean basin. Every ocean on Earth has a basin and these five major basins are the Indian, Atlantic, Pacific, Artic, and Antartic ocean basins. The Earth holds a great deal of water in rivers, lakes, streams, and seas but over 70 percent of the Earth 's water is held within the ocean basins. I will be discussing the history and formation of the ocean basins, the types of terrain and their function, and the sediments that lie on the ocean floor. Ocean basins first formed as a result of volcanism, with magma reaching the surface and releasing steam into the atmosphere, through out gassing. The steam formed clouds of water vapor which in turn produced rain, in time, filling the depressed areas of Earth with water which formed the first ocean basins. In paleoceanography, before the break up of Pangea, there existed only one mass of water, known as Panthalassa and the connecting Tethys Sea, during the Permian age. As we move into the break up of Pangea and the formation of modern day oceans, fast forwarding over 200 million years, we get the five major ocean basins. The formation of these new basins can be seen as a direct correlation
