What’s the Right Theory About the Dinosaurs?
In many theories about the dinosaurs disappearing many say meteors are the reason, is that true? The many theories about dinosaurs disappearing is a huge meteor or asteroid,climate change, volcanic eruptions, lava,and fractured crystals. At the same time there are over 40 theories of why the dinosaurs disappeared, but I only listed the most important ones that were mentioned the most. The biggest theory of all of them is the Asteroid , people think the meteor collided with earth consequently it, struck it so hard that enough dust consequently debris came up and blocked the sun and it pushed the sun out long enough to that the earth's climate changed, most of the plants died out and that caused …show more content…
However, such a severe crash would not have only left a huge hole in the ground but caused other devastating consequences. Most meteors hitting the Earth do so at speeds of 10 to 20 kilometers per second. The speed of the object as well as the mass of this asteroid On another note there is another theory called the climate change theory. So during the dinosaur time the climate was most likely hot and human, there was no proof of ice ages or glaciations during this time because there was no proof in the rocks. Thing is they found lots of evidence of tropical species existing at the time of the dinosaurs. A gas called Atmospheric carbon dioxide was close to the levels we have today. But, during this time the ice caps from the north and south had melted. Which after resulted in raised sea levels. With this time pangea ( A supercontinent to where all the continents were all connected.) was also changing, Australia was breaking away from Antarctica and gradually moving away from the South Pole, closer to the Equator. The major plants that were dominating australia were conifers and ferns and by dominated I mean the land was covered in them, Thing is half of australia was covered in shallow inland seas. Evidence from this was found in the fossils from the rocks, they contain certain species from the time like marine molluscs and large prehistoric …show more content…
The MIT and princeton researchers used high precision geochronology to determine the age of rocks on the so called deccan traps. To evaluate whether the extinction happened before or after the volcanic eruptions. The researchers collected more than 50 samples of rocks from that certain region in india to record data, Fortunately, samples from both the bottom and top of this volcanic layer contained zircon, allowing the team to pinpoint the timing of the beginning and end of the Deccan Traps eruptions. During the time of the volcanos erupting, over 10,000 volcanos erupted and because of all of this the volcanic dust blocked the sun and because of the sunlight being blocked then had the earth get less oxygen than having the dinosaurs then suffocate because the volcanic dust lowered the oxygen
