Depends on where the chunks land. If our yellowstone chunk lands in what now is the Sahara it'll desertify over time, for instance. That's something to look into, I guess!

So the people on the Yellowstone chunk were on it before the blast, I presume?

That's the idea, people managing to survive the chunks flying off and being pulled back.

And that might not actually work that way, considering that the sahara would've been launched off with everything else XD We're talkin total planetary 'boom' and 'unboom' here... and it's not as if what pulled it back together has the finnesse, or time, to organize everything back the way it was... Besides, the Sahara's mostly sand, bits of saharan sand probably got scattered across half the hemisphere it's on XD There's also the existence of holes between chunks here and there, new bodies of water happening, so on and so forth.

Lets not forget that Yellow stone is kindof a ginormous fucking volcano too, dormant or not XD
