The ambiguous definition of the word continent, in its geographical sense, has led the scientific community to a lack of consensus in order to establish how many continents there are and what they are. Consequently, there are currently different models that defend a varying number of continents based on the following criteria:
2. VARIABLES THAT DETERMINE THE DIFFERENT MODELS
- If only the populated continents are considered (America, Europe, Africa, Asia, and Oceania).
- If you consider Antarctica a continent.
- If America is understood as a single continent or as two (North America and South America).
- If Europe and Asia are considered a single continent (Eurasia), because there is no land discontinuity between them.
- If Europe, Asia, and Africa are considered as a single continent (Eurafrasia), because there is no natural separation between them.
- If you do or do not consider the last continent discovered: Zealandia.
Taking these criteria into account, six main models that range from 4 to 8 continents are established. You can reference those models [HERE].
3. THEN … HOW MANY CONTINENTS ARE THERE?
There is no scientific consensus, therefore there is no single answer. In any case, of the six main models, there are three more popular/widespread models:
– The model of five continents (the classic and most populated): America, Europe, Africa, Asia and Oceania. (*) Used by the United Nations and the International Olympic Committee.
– The model of six continents (the previous five plus Antarctica): America, Europe, Africa, Asia, Oceania and Antarctica. (*) The most popular model in Latin America.
– The model of seven continents (taking into account Antarctica and America divided into North and South America): North America, South America, Europe, Africa, Asia, Oceania and Antarctica. (*) Model defended mainly by English speaking countries.
