The Volcanoes that Killed the Dinosaurs

"... To date 99.9% of all species have been extinct." (Benton 1) After 160 million years of governance, the dinosaurs were governed by fire and ice. 65 million years ago, the biggest volcanic eruption ever happened in India, effectively destroying dinosaurs by blowing poisonous gas and ash, effectively killing the plants and destroying the food chain by the sun We stopped. The dinosaur died of starvation.

Some people think the volcano has killed the dinosaurs. When the volcano erupts, it is the idea that the dinosaur will not give plants and plants necessary for survival, because it will destroy a lot of dust and debris and block the sun. When it occurred, the lava was thought to immediately burn some dinosaurs and destroy the entire ecological food web. A more general assumption is the idea of ​​comets. Some scientists believe that a huge comet hits the Earth and that many dust and debris can not fly out and grow plants to block the sun. Because large herbivores require enough plants to survive, they disappear first. Without a large herbivorous animal as a food source, a huge carnivore quickly dies. The comet itself crushes many dinosaurs. Only small animals and insects can tolerate this disaster

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)

The extermination of dinosaurs due to the influence of asteroids does not precisely know how dinosaurs were extinct. However, scientists have guessed for decades that led to the death of the dinosaurs. Its possibilities range from asteroids to volcanoes, to climate change. - Summary of the effects of meteor and asteroids According to theory, years ago a huge meteor destroyed all the dinosaurs on the earth. Since that time, scientists have found evidence that millions of meteors hit the earth. However, recently, we are still threatened by the influence of another meteor, so scientists are trying to find the exact way to track and predict the meteor's trajectory. This is the meaning of most of my project.
