I think it was the continental drift because I read that the continental drift broke it apart. I don't think it was flood because there would have been more land before all the continents formed for a flood to have happened. At one time all the continents were together called the Pangaea and that had to move to create our 7 continents now, there was a problem with the magnetic force of the mantle said scientist and that made it separate (the continental drift). Scientist also said that at one time when it was in continental drift two continents bumped into each other and created another continent. If that is true then there couldn't have been a flood because there would have only been 6 continents.Also scientist said that if there was a flood then all of land that we are on now would have been mountains because the part of the Earth that didn't go under had to be tall.

I think that Pluto shouldn't be qualified as a planet because the qualifications for a planet is that it has to be large, it needs to orbit around the sun, and it has to have a fairly round shape. The planet Pluto has a sort of oval shape to it and it is very small. Pluto is also considered a dwarf planet which doesn't qualify for a planet. Claudia C. Period 4
