In the late 1960 early 1970's in the United States I was taught that there were 6 continents, combining Asia and Europe to make Euroasia. My students think that could not have been in the US curriculum. My question, did the US ever teach the 6 continent model were we included Europe and Asia as one?
Answer 1:

There isn't a precise definition of a continent. For geopolitical reasons, Europeans have liked to separate themselves from Asia, even though Europe and Asia have been part of the same landmass since before Pangaea broke up. BEFORE Pangaea, Europe and Asia were separate (indeed, Asia itself was had about three or four major pieces). However, using this definition India, Madagascar, New Zealand, the Arabian Peninsula, and arguably even Greenland also qualify as continents.
