Theories on Dinosaur Extinction

The dinosaur extinction theory killed the dinosaurs. Over time, several theories have been proposed to answer this question. Many scientists are very interested in how dinosaur-sized creatures are destroyed. Proposing theoretical climate change theory Some scientists suggest that climate change is killing dinosaurs before the attack of famous asteroids. Fossil evidence shows that the average temperature drops from 25 degrees Celsius to 15 degrees Celsius and annual rainfall decreases.

The theory of dinosaur extinction develops mainly on the extinction of dinosaurs. According to a theory, at the end of the dinosaur era, the environmental change associated with the progressive withdrawal of the shallow ocean of the continent brought the dinosaur out of extinction. Supporters of the theory suggest that the number and type of dinosaurs will gradually decrease after millions of years. "Suddenly, it was a small pea, a beautiful blue, the earth that shocked me suddenly, I set my thumbs, closed my eyes, my thumb dirtied the earth, like I was a giant I do not feel I am Neil Armstrong said that this is his famous trip, he was the first man on the moon, one of several people with opportunity. Earth has always been the residence of mankind since.

Dewey McLean (1978) has become the most common theory of extinction of dinosaurs in science since proposing the dinosaur extinction theory that climate change kills dinosaurs. It is called the dinosaur - the greenhouse extinction theory. It said that climate change due to greenhouse effect led to the death of dinosaurs. My paper adopts this proposed theory and connects it to the world of today. If dinosaurs and greenhouse extinctionism holds, we may die with the mechanism of the killing of greenhouse vertebrates, sudden atmospheric changes, and other influences. As the greenhouse effect increases, people should understand our impact on the earth. In my thesis, I will examine the similarities that occurred during the two periods and the results that may be encountered in the near future.

A: Nemesis theory is one of the theories "come from outer space" of dinosaur extinction. The idea is that every twenty six million years the comet will approach the Earth, bring more debris to hit the Earth, change the weather and kill many animals. Perhaps they killed dinosaurs, pterosaurs, and large reptiles 65 million years ago. In related theory, there is evidence that asteroids lead to extinction and huge asteroid craters were discovered in Mexico about 65 million years ago. However, I do not know if dinosaurs are enough, or whether dinosaurs have disappeared or have completely disappeared or not already happened. The truth is that we will not lead to extinction of dinosaurs, it may even be a combination of asteroids, volcanoes, moderate climate change, and even diseases. This is a mystery! (Don Lessem)
