Is that neat rock you found a meteorite? Probably not, but to be sure, you might want to use this handy flowchart by Randy L. Korotev of the Washington University Department of Earth and Planetary Sciences. It was adapted from a simpler chart from Deborah Guedes. But if you want a really simple chart, check out Randall Munroe’s version. -via Boing Boing
Wait... if someone saw it FALL, it's NOT a meteorite? And there's no "No" option from there?
