What is the largest ocean in the world?

What is the largest ocean in the world? The Pacific Ocean is the largest ocean on Earth. It covers about 165.25 million square kilometres, making it larger than all of Earth’s land area combined.

The Pacific stretches from the Arctic Ocean in the north toward the Southern Ocean near Antarctica. Asia and Australia lie along its western side, while North and South America border it to the east. Its name comes from the Latin mare pacificum, meaning “peaceful sea,” a name associated with Ferdinand Magellan’s voyage in the 16th century.

The Pacific is also the deepest ocean. The Mariana Trench, located in the western Pacific, contains Challenger Deep, the deepest known point in the world’s oceans, reaching nearly 11,000 metres below sea level. The ocean contains thousands of islands, including many formed by volcanic activity.

A common mix-up is confusing the Pacific with the Atlantic because both span enormous distances and contain major shipping routes. The Atlantic is important historically and economically, but the Pacific is larger in area, deeper overall, and holds the greatest volume of ocean water.
