I had to consult the web for this one.
You're right, there's the old model with 7 continents (North & South America, for example).
Now, they've got the Americas combined and Europe combined with Asia and, in another model, Africa, Europe, and Asia all combined.
In my mind, it's GEOGRAPHY and being able to identify a LAND MASS.
It seems like these new models are just trying to push young minds into accepting the new one world order.
