A meteor hit the earth making it impossible for the sun rays to penetrate the dust the meteor had created, not only that but forest fires where starting all over. The Earth was dark and cold impossible for the animals and plants to survive. As also great amount of acid rain started to kill most species. After the dust clear up, green house gases made by the impact made the temperatures go up.
Years after, the hypothesis stated that freezing and hot temperatures caused the extinction of dinosaurs and also of 70% of all plants and animals. It was freezing because there were no rays from the sun to warm up and hot because of the fires.
