    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. :biggrin:

    Cold is the short answer. Ice cores from Greenland are pretty compelling. Earth was in one of its frequent ice ages back then. Volcanic eruptions, and possibly collisions with asteroids/comets, appear to trigger ices ages.
