it depends on the size of the comet if it was small it would do about 5o/ out of a 1000 on earth if it was a very big one it would do about 989/ out of a 1000 so it depends on size
Probably by a big explosion caused by a meteor or a comet
Depends on how big the Comet is.
it could be the end of the earth
Probably an asteroid, meteor or comet.
a big giantic hole in the ground
A meteorite had hit the earth and there was a big explosion. And all the dinosaurs died.. :(
Yes they all could destroy Earth depending how big it is, how big the impact is when it hits, and where it hits,but its possible. Hope this helps.
Big comet maked bigger comet died
halley's comet is smaller than the earth because ,if it is smaller than the moon it will surely be smaller than the big earth.many comets are bigger than the earth also.
I assume you are referring to the Cambrian Explosion... It was a period on Earth many millions of years ago after heavy bombardment from asteroids. A huge "explosion" of species and life came to form on Earth.
Some comets might also be invisible from Earth, we only see the big ones.
Some famous comets and their names include Halley's Comet, Comet Hale-Bopp, Comet Shoemaker-Levy 9, and Comet 67P/Churyumov-Gerasimenko. Each comet is named based on the astronomers who discovered them or based on a specific naming convention.
