Almost as old as Earth itself, oceans dominate the planet’s surface. Life first evolved in the oceans, and today they are home to a vast diversity of species. By transporting huge amounts of energy, the oceans also help to power and modify Earth’s climates.

Earth is a watery world, with 68 per cent of the surface covered by saltwater oceans. Each of the five major ocean basins (the Arctic, Atlantic, Indian, Pacific, and Southern) is a deep depression in Earth’s surface. Connected to the oceans, and typically partly enclosed by land, are numerous smaller seas such as the Mediterranean and Bering seas. Oceans are partially separated by landmasses but are all interconnected.

The familiar layout of Earth’s continents and oceans is very different from the way it was in the prehistoric past. Today’s oceans and their seas arose gradually as early landmasses split up and moved apart. Scientific evidence suggests that the original ocean formed from water vapour that escaped from the molten surface of the planet. Around 3.8 billion years ago, conditions cooled and this vapour started to condense and fall as rain.
