Ever heard of the hydroplate theory? Prior to the flood the earth was semi-arid with average 70 degree temps everywhere (including the poles) and mountain ranges no more than 1 mile high. Incidentally if you were to lower the sea-levels worldwide less than 100 feet all of the continents would be connected by land-bridges.

As it does so, you see the continents and land masses begin to come together like matching puzzle pieces, until at some point, every open area has closed and the whole planet is a smooth, unbroken plain.
It's very convincing, and so is his detailed study of it. Well worth a look:
