Some creationists have claimed that Noah's Flood was followed by superfast continental drift, in which Pangaea broke up and its fragments moved to near their present positions in only a few centuries -- at most.
However, there is evidence that continents have been drifting and colliding and breaking up over the last few billion years, as if they are playing a game of "bumper cars".
Here is
Chris Scotese's excellent site and
Steven Dutch's drift-history page; they trace continental drift from the breakup of Rodinia, a Pangaea-like supercontinent, about 750 million years ago.
Rodinia had formed about a billion years ago from previous continents; these continents have been traced back to an earlier supercontinent of 1.5 billion years ago,
Columbia.
There may have been an even older supercontinent, at about 2 billion years ago, but details on that are not very clear -- I recall it from somewhere.
But before that, the continents were relatively small, and they may not have a tendency to form supercontinents.
