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 occupies two-thirds of
planet's surface. These are, in descending order by area, the Pacific, Atlantic,
Indian, Southern (Antarctic), 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. Source
