The world’s largest body of water, the Pacific Ocean, covers about one third of the Earth’s surface. This massive ocean is double the size of the Atlantic and contains twice its volume of water! The area of the Pacific Ocean, without its surrounding seas, is 165 million square kilometres. With the Seas of Japan and Okhotsk, the Bering, Celebes, Coral, East China, Sulu and Yellow Seas, its total area exceeds 179 million square kilometres. All of the continental land masses on the planet could be placed in the Pacific Ocean, and there would still be room left over!
