Generally early in elementary school. (Or they did when I was there, anyway.) Oh, and at least bits of the continents are solid rock, right? I mean, mountains and things.



Oh, and it's not at all what I learned in college, either. My professor had gotten his PhD maybe two years earlier, and this was perhaps seven years ago. So if this massive change of information has happened, it's been in about the last ten years.



And for the love of Gods, it's Pangaea. Greek "Gaea" for "Earth." Same route as, well, geology, which our friend Neal has clearly not studied enough.
