The World's Largest Meteor Crater.

Two billion years ago, a meteorite (measuring the size of 10 km in diameter) hit the earth 100km southwest of Johannesburg, South Africa. Result? Enormous impact crater. This meteorite, which is rumored to be the very same one that caused the extinction of the dinosaurs, was as I've previously stated 10 km in diameter. It was even larger than the Table mountains. This astonishing impact, who's site measured 380 km, may have increased the earth's oxygen levels to a point that made the development of multicellular life possible. Even though this impact site has a high chance of being the one that was big enough to kill the dinosaurs, the world itself has 130 crater structers that could've been the real one.Vredefort Dome ( the place the meteorite hit) is one of the top three, since it is the oldest (65 million) and largest clearly visible meteorite impact in the world. I presonally think, this impact site is what killed the dinosaurs and I hope nothing like this happens again. Noone is sure why the meteor hit, since we weren't around to study it. A simple guess of mine is that the meteor got pulled into the earth's atmosphere by it's magnetic pull and it was too big to get burned up in the atmosphere.
