It seems quite impossible for the continents to have moved any great amount during a supposed global flood. Think of the tremendous energy in one large earthquake event. Imagine part of California or Japan moving a few feet. Now imagine all of the continents moving at a rate of many miles per day during this flood event. Imagine the continents having to suddenly start to move at the beginning of a global flood event (why would even a great flood make continents move?), move I don’t know how many miles per day during this event and then the continents slow down to something close to their current rate of movement. I cannot help but imagine that if the great land masses were somehow (again, how?) forced to move so much in such a short period of time, that the energy involved would have melted the earth’s crust.
