Continents

I'm voting for there being 4.

The 7-continent model is usually taught in Western Europe, the United States, and Australia. In Canada, the government-approved Atlas of Canada names 7 continents and teaches Oceania instead of Australia. The 6-continent combined-America model is taught in Asia and Latin America. The 6-continent Eurasia model is preferred by the scientific community, and as such is commonly found in all parts of the world, but is especially used in Russia and other countries of Eastern Europe, and in Japan. Historians may use the 5-continent model in which North Africa is separated from Sub-Saharan Africa and attached to Eurasia (Jared Diamond) or the 4-continent Afro-Eurasian model (Andre Gunder Frank).
