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.
