The Greatest Body of Water
Earth is often called the blue planet, and for good reason: most of its surface is covered by water, divided into great oceans. Of all these oceans, one stands far above the rest in size. The largest ocean in the world is the Pacific Ocean, a body of water so enormous it is difficult to truly imagine.
A Truly Enormous Size
The Pacific Ocean is staggeringly large. It covers roughly a third of the entire surface of the Earth. To put that in perspective, the Pacific is so big that if you took all the land on the planet, every continent and island combined, it would still fit inside the Pacific with room to spare. It is also far larger than the next biggest ocean, the Atlantic, holding much more water.
Where the Pacific Lies
The Pacific Ocean stretches across an immense part of the globe. It sits between the great landmasses of Asia and Australia on its western side, and the Americas on its eastern side. It reaches from the cold waters near the Arctic in the north all the way down toward Antarctica in the south. Thousands of islands are scattered across its surface, many of them tiny specks in a vast expanse of blue.
A Name That Means Peaceful
The name "Pacific" actually means peaceful. It was given by an early European explorer who, after a difficult voyage, sailed into a stretch of unusually calm water. But the name can be misleading. The Pacific is also home to the deepest point in all the world's oceans, and its edges are ringed by a zone of frequent earthquakes and volcanoes. So this "peaceful" ocean is, in truth, a place of great power and depth.
