The thing I find most interesting about Pangaea is that, if all the landmasses were connected, it leaves a massive amount of uninterrupted ocean everywhere else. It seems to suggest that there is a significant difference between the two areas of Earth; one area being where Pangaea was located, and the other area being the rest of Earth.
Why would only that portion of the Earth be above water? Is there something significant about where Pangaea was located which made it different from the rest of the Earth?
