People normally consider there to be 7 continents. But these continents are not defined by exact science, but rather by convenient labels that have been adopted over time. For example, Asia and Europe are part of the same singular land mass called Eurasia. But they are generally considered separate continents because of cultural and historical reasons. There are 7 continents: Australia, Europe, Antarctica, South America, North America, Europe, and Australia.
Some of the continents have very vague boundaries between them, so we apply aribtrary boundaries to them.North America and South America are normally divided at the Panama Canal, despite it being an artificial canal. Africa and Asia are separated by the Suez Canal,again by an artificial canal. These unnatural boundaries show that the continents are not easy to define with precision.
Let's now take a look at the world's oceans.There are 5 oceans, though many people forget one of them. They are the Southern, Arctic, Indian, Atlantic, and Pacific Oceans. The Arctic and Southern Oceans are often merged in with the first three oceans, and that is the reason many people don't know about them, particularly the Southern Ocean.
The Southern Ocean is situated in the southern portion of the globe, in the vicinity of Antarctica. It revolves around the Antarctic continent and merges into the Atlantic, Indian, and Pacific Oceans at its northern edge.
