How do they know that a meteor hit the earth and wiped out the dinosaurs?

That's the leading theory based on tons of evidence from the fields of geology, archeology, Paleontology, and evidence from ice plugs taken in the arctic and antarctic. There are two candidate sites for where the meteor hit: some take Iceland as where it hit, but most scientists think that the meteor struck what is now off the coast of the Yucatan Peninsula. For a more detailed discussion, go to the library and check out a book on this theory. (Remember: A theory in technical use is a more or less verified or established explanation accounting for known facts or phenomena: the theory of relativity.)

∙ 14y agoWell, there are many theories of how the dinosaurs were wiped out, and different reasons to believe different theories. Most people believe the dinosaurs were wiped out by a meteor because it makes the most sense. There was a huge crater found that people believe is the spot where the meteor hit. It also makes sense because of the Loch Ness Monster. Why? When the meteor hit, all the water dinos must have gone under water, so they wouldn`t be killed by the meteor. The Loch Ness Monster is probably a Pleasieousaurus left over from millions of years ago. But no one will ever know for sure what killed the dinosaurs...

∙ 13y agoThe end of the dinosaur era came suddenly and it coincided with a time when a meteor hit the earths surface. the result of this collusion would have been that life as it was on earth at the time would have become impossible, killing just about everything that lived on the surface and changing the ecology of the earth to a point where it would no longer be able to support animals as big as the dinosaurs even if some did survive.

How do you know a meteor wiped outh the dinosaurs?
Well we're not completely sure if that was the cause of the extiction. This is however the most likely theory of extinction. The other theories are volcanoes which expeled carbon dioxide into the atmosphere that made it hard for the dinosaurs and other large animals to breath, a new poisonous plant species that wiped out the dinosaurs, disease and much more. But we do have a lot of evidence of a meteor hitting the Earth, for instance: There is a large crater like hole in the gulf of Mexico, that hole has a samall gravitational pull (which is what they think the reason for the Bermuda Triangle is) and there are minerals and elements that are found in meteors in that area.
How did alligators and crocodiles survive the meteor that kill the dinosaurs?
There is no way of knowing what killed the dinosaurs millions of years ago. We don't know if it was by volcano, meteor, or an ice age.
In the future will there be a meteor right and you will all die like the dinosaurs did?
First of all - we don't know for sure that a meteor killed the dinosaurs. There are dozens of theories and no solid proof. Secondly, it's possible.
What was the bomb that wiped out the dinosaurs?
There was no bomb that wiped out the dinosaurs. Actually in the bible, the dinosaurs were wiped out by the flood when God flooded the whole world and save Noah, his family, and 2 of each animal. They were kept safe from the flood on the ark which is a big boat. Dinosaurs were not big enough to fit so they were killed by the flood. If you would like to know more info, it is in Genesis chapter 5 and 6 in the Bible In the scientific world, it is widely believed that a large meteor approximately the size of Washington DC collided with the Earth about 65 million years ago. The site of the impact is just off the northern tip of the Yucatan peninsula in Mexico. The crater left behind has been long since filled in by displaced ocean water and erosion.
What killed the dinosors?
A meteorite from space that blocked out the sun and made acid rain which poisoned all the plants so herbivores died out, with no food supplies for carnivores they all died out. Good bye Tyrannosaurus Rex.:(
What percentage of life was wiped out with the dinosaurs?
Earth is 4.55 billion years old. If you don't count birds, Dinosaurs were around for 166 million years or about 3.6% of Earth's history. If you count birds as dinosaurs, which most scientists now do, dinosaurs have been around for 231 million years or about 5% of Earth's history.
How did dinosaurs survived?
Well, they didn't they died because of possibly a meteor hit Earth during the Mesozoic Era only birds survived but technecially birds are not are not dinosaurs if you want to know that go to another website
How did the dinosaurs got extinct?
I am guessing you are asking why dinosaurs went extinct. Scientists have not come to a conclusion as to why they went extinct. However, there are many theories which could answer your question. Some scientists believe that dinosaurs went extinct because of a large meteor which could have crashed into the earth and wiped out any exposed animals. There is also a theory that the weather changed for the worst, causing dinosaurs to die. Although there is no agreed answer to your question, it is up to you to decide why exactly they went extinct.
