What would happen if a comet hit earth?
It Would Be The End Of The World As We Know It :)
Fixed: It would cause earthquakes and tsunamis, but it WON'T end Earth. It do so much as to only dent it a little.
A comet that does not hit the Earth would cause no damage at all. A comet that hits the Earth would be as destructive as many nuclear bombs, depending on how big it was and where it hit. It is likely that a giant comet or asteroid hit the Earth (near Mexico) 65 million years ago, resulting on the extinction of the dinosaurs and 90% of all land life on Earth.
Comets have hit the Earth before; there is no reason why a comet could not hit the Earth in the future. Unless we prevent it, which is what would probably happen. This year? Certainly not; we would have seen it before now. Within the next ten years? The odds of that would be VERY low. Within the next 1,000 years? Could be. Within the next BILLION years? Almost certainly yes. Within the next 2 BILLION…
