<P> An ocean ( from Ancient Greek Ὠκεανός , transc . Okeanós , the sea of classical antiquity ) 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 . 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 . </P>
