I say continental Drift because our plates are always moving each year. Also because when the super-continent split or divided animals fell through and there is now there is fossils in the ocean. Also because in one of the articles it said the earths crust it not a solid shell. The plates that divide the super continental move 1 to 10 centimeters a year. And also are 20-250 miles thick (80-400km). I also think divergent plates caused it too. Since divergent divides. Also they drifted away.
