What elements have led scientists to believe that a meteor caused the extinction of the dinosaurs?
When all clues lead to the same conclusion, a theory is born into fact.
How do scientists believe that a great flood killed the dinosaurs?
Scientists do not believe that the extinction of the dinosaurs was the result of a great flood. There are still a number of competing theories about the extinction of the dinosaurs although it is clear that there was a large meteor impact in the Yucatan region, which played a role. It may also be that rising carbon dioxide levels and ocean acidity played a role as well. It may be that there were a number…
Did tsunamis cause the dinosaur extinction?
No. Scientists believe that a giant meteor hit the Earth, killing all the dinosaurs and causing their extinction. It is true that the extinction of dinosaurs is mostly due to the meteor that hit earth during the time but according to scientists, only around 60 percent of the organisms on earth died due to direct impact. Some other reasons the dinosaurs are extinct may have included climate change, competition, or volcanic eruptions. And on the…
What really killed the dinosaurs a volcano or a meteor?
Nobody knows that for sure, because nobody was there to witness the K-T Extinction Event. However, most scientists believe that the asteroid impact killed off the dinosaurs. Although volcanism related climate change was reducing the biodiversity of dinosaurs, they would have survived if it hadn't been for the asteroid impact.
Where did the dinasors go?
All Dinosaurs became extinct long ago. Why did dinosaurs become extinct? There are many theories as to why dinosaurs disappeared from the Earth about 65 million years ago. Scientists are divided between two primary schools of thought on the subject: the gradualists believe that the dinosaurs' extinction was a gradual process, and the catastrophes believe the dinosaurs were wiped out by a single catastrophic event. The gradualists propose that the dinosaur population steadily declined at…
Most scientists believe the extinction of Mesozoic life was caused by what?
It's hard to assign a belief about the cause of the Mesozoic mass extinction to 'most' scientists. We have evidence for one or more meteoric impacts such as that at Chicxulub, massive volcanic eruptions such as the Deccan Traps in India, and changing climates due to the shifting of tectonic plates. Many scientists favour one reason over another, and others think it may have been a combination of all these factors.
What fell into the earth when dinosaurs lived?
Some scientists believe it was a large meteor that crashed into the earth disrupting the food resources and proper atmosphere, which led to the large dinosaurs dying off. Some scientists believe it was a large meteor that crashed into the earth disrupting the food resources and proper atmosphere, which led to the large dinosaurs dying off. Some scientists believe it was a large meteor that crashed into the earth disrupting the food resources and proper…
Where did the comet that killed the dinosaurs land?
It is widely accepted that one asteroid with a 6 mile diameter crashed in the Yucatan Peninsula, leaving the Chixculub Crater. However, there are some scientists who believe that there were multiple asteroid impacts at the end of the Mesozoic. Possible other craters include the Boltysh in Ukraine, the Silverpit in the North Sea, and the much more controversial Shiva crater in the Indian Ocean. Some scientists believe that the Chixculub impact predated the extinction…
How big was the meteor that was said to have led to the extinction of the dinosaurs?
Although there is much speculation over what actually caused the extinction of the dinosaurs, a large meteor did, in fact, strike the Earth shortly before the dinosaurs' extinction. The meteor is believed to have been approximately 10 kilometers in diameter. The impact location was the Yucatan peninsula and the event occurred around 65 million years ago. If the dating is correct this places the impact during Cretaceous period, which has led many to believe that…
What organisms went extinct at the time dinosaurs did?
Many types of large reptiles died out, along with non avian dinosaurs, during the K-T mass extinction. These include pterosaurs, plesiosars, mosasaurs, and marine crocodylomorphs. Ammonites, a highly successful group of molluscs, became extinct. On land, scientists believe that no species larger than a housecat survived.
What is the volcanic theory for the extinction of dinosaurs?
For ten million years prior to the K-T Extinction that wiped out the dinosaurs, massive volcanic traps were erupting in India. They released massive amounts of greenhouse gases, which altered the climate. The altered climate had decreased dinosaur biodiversity to one tenth of what it had been by 65.5 million years ago. Some paleontologists believe that this is what wiped out the dinosaurs.
If scientists were to find a large crater dated around the time of the dinosaurs what might it indicate about their extinction?
Many people actually believe that A large flood killed all of the dinosaurs, A large earthquake caused the crater that engulfed the dinosaurs, or A large volcanic eruption resulted in global climate change., but no. it was actually that of A large asteroid strike resulted in a massive explosion that altered plant life. It created an explosion so big that it basicly wipes out the entire species of dinosours!
