World Oceans

Scientists now recognize five bodies of water as oceans today: Pacific, Atlantic, Indian, Arctic, and Southern (also called the Antarctic). Depending on the authority, seven oceans may be identified, with the Pacific divided into the North and South Pacific and the Atlantic into the North and South Atlantic. Table 1.1 summarizes some major properties of the five oceans.

Continents and Oceans

There is an old saying that “the Earth has six continents and seven seas.” In fact, that generalization is not too far off the mark. Earth has six continental landmasses:
Africa, South America, North America, Eurasia (Europe and Asia occupy a single large landmass), Australia,
and Antarctica. As for the seven seas, there are five great oceanic bodies of water and several smaller seas.
