That is just the first slippery step on a well-oiled slope. What about North America and Asia?
They are connected by the Bering Sea Shelf, once dry land crossed by humans and flooded only in the geologically recent past. Technically speaking, that makes Asia, North America and Europe all one continent. Does that mean there are only five?
Other experts contend that five, six and seven are wrong and argue in favor of eight continents. There are even those who go as far as to say there are only two.
Hiding within the simplicity of the song, there is an illusion of general agreement about the number of continents.
