Sounds like a homework question. What research have you done?
Ah. A review of your past posts suggests you're writing a sci-fi story.
Still, a quick wiki of plate tectonics or continental drift would probably be better than having to give us all credit in your book for doing your basic research for you.
thanks i'll stop bugging you all..;)
