This article is very interesting and it got me thinking. They left out lots of information that would be helpful to this cause like: Did a meteor hit 250 million years ago? They didn't say that a meteor did hit, they just said that there was some evidence that a meteor hit 220 million years ago. If so, what animals did it kill? What population of those animals did the meteor kill? I think that the information in this article is insufficient, and needs to be added upon. I'm looking forward to reading comments concerning additional facts!
I'm really glad that these meteorites
are very rare because it would be extremely bad if a gigantic rock from outer space came and wiped out almost 70% of life on the planet.
I looked up some facts about meteorites and learned that there are stone meteorites, iron meteorites, and stoney-iron meteorites.
I would hate for one of these giant meteorites to crash into earth. (again). I agree with Nathan that it would be bad if a giant rock from space wiped out 70% of life. Some recent articles in magazines and the movies we watched at the science museums.
WHY DOES EVERYBODY ONLY COUNT THE LAND POPULATION!!!!! It wiped 70% of land species and 95% of ocean species clean off the earth. how big was the meteor? were the species that left animals and plants, or just one? also, I didn't know that antarctica had dirt. I just thought it had ice and snow. but, then again, doesn't the snow have to be on top of something other than ice? this article was very vague from my point of view.
This is interesting. The idea of a meteor wiping out ancient life ties in with the comet idea at the Discovery Center. They both share one theory: that some space projectile wiped out ancient life.
This is kinda scary that two meteors have hit the earth in the past 250 million if two meteors hit imagine how much animal/other life must have been killed. I also agree with nina on the subject.
How can these scientists know what percentage of animals were wiped out? I guess they could assume by looking at the fossils. BUT 250 MILLION YEARS AGO!!! That doesn't make much sense. What scientific method do they use and how? What is the oldest fossil that has ever been found. I am going to check on the internet. 3.45 BILLION YEARS AGO WAS THE OLDEST FOSSIL SCIENTIST HAVE EVER FOUND!! It was found in North West Australia. Then again, that still doesn't answer my question about how they know what percentage of living organisms died. I agree with Nathan and Alexis that i would hate for a giant meteorites to crash into earth.
Radical article dude!
I love Miss Ghazarian!!
that wasn't me sorrry
i accidently pressed publish. I was doing that as a fake comment. Even though i do love her.
I know that if some meteors and asteroids come close to Earth, we have the technology to know that ahead of time. But what would we do to stop it? Would we try to blow it up, or would we try to change its course. If we try to blow it up, where would we know where the pieces would go? Maybe if they were large enough, they would break up in the Earth's atmosphere anyway. And if we try to change the course, how would we do it? Would we land a rocket on the meteor and put rockets on it to move? If ONE meteor can kill almost 70% of life on Earth, then how many different ways can we protect ourselves? Or can we? That is what we need to know.
