so, that pangea thing.

well, that's the theory(his anyway).
kinda makes sense in some ways. there are arguments that in order to 'grow', mass would needed to be added. i think that if the core of the earth is that hot then expansion seems possible.
also, some say the universe is expanding, so why not earth?
then there is the techtonic movements..some say that 'folds' and mountains prove that techtonics(sliding) happen...but, if these areas along faults are weaker than it also makes sense that the force of magma could create uplift along faults.
one thing that had me thinking though was if the planet was once a lot smaller and it was all one single land mass, then where did the ocean come from?...unless the expansion created a global warming by getting closer to the sun,making heaps of rain?..dunno.

while not one to fully rely on wiki, i;ll go with this theory....
"The cooling of the primordial Earth to the point where the outgassed volatile components were held in an atmosphere of sufficient pressure for the stabilization and retention of liquid water."

well my only guess as to where all that water came from..
... would have been around the time of the stromatolites, one of the first organisms on earth, that took in the copious amounts of carbon dioxide, and produced oxygen in massive massive amounts.. the exponential amounts of oxygen in the atmosphere would have found a bind with carbon molecules, and zappy pop, created water.
there must be some sort of theory about that on the net somewhere, and if there isn't.. I am very wrong.
