ThePacific Oceanis the largest and deepestofEarth'soceanicdivisions. It extends from theArcticOceanin the north to theSouthern Ocean(or, dependingon definition, toAntarctica) in the south and is bounded bythe continents ofAsiaandAustraliain the west andtheAmericasin the east.At 165,250,000 square kilometers (63,800,000 squaremiles) in the area (as defined with a southern Antarcticborder), this largest division of theWorld Ocean—and, inturn, thehydrosphere—covers about 46% of Earth's watersurface and about 32% of its total surface area, largerthan all of Earth's land area combined (148,000,000square kilometers).[1]The centers of both theWaterHemisphereand theWestern Hemisphereare in the PacificOcean. Ocean circulation (caused by theCoriolis effect)subdivides it[citation needed]into two largely independentvolumes of water, which meet at theequator:theNorth(ern)Pacific OceanandSouth(ern)PacificOcean. TheGalápagosandGilbert Islands, whilestraddling theequator, are deemed wholly within theSouth Pacific.[2]
Its mean depth is 4,000 meters (13,000 feet).[3]Challenger Deepin theMariana Trench, located in thewestern north Pacific, is the deepest point in the world,reaching a depth of 10,928 meters (35,853 feet).[4]ThePacific also contains the deepest point in theSouthernHemisphere, theHorizon Deepin theTonga Trench, at10,823 meters (35,509 feet).[5]The third deepest point onEarth, theSirena Deep, is also located in the MarianaTrench.The western Pacific has many majormarginal seas,including but not limited to theSouth China Sea, theEastChina Sea, theSea of Japan, theSea of Okhotsk,thePhilippine Sea, theCoral Sea, and theTasman Sea.Contents1Etymology2Largest seas in the Pacific Ocean3History3.1Prehistory3.2Early migrations3.3European exploration3.4New Imperialism4Geography4.1Bordering countries and territories4.1.1Sovereign nations
