How did the dinosaurs die out?
DANG, IT! They didn't die. In fact, they excreted on your car last Friday.
An asteroid impact
Because of volcanoes
Because of the Ice age
A FLOOD 500 years ago

Answer:
Though the first dinosaurs appeared about 243 million years ago, they remain as prominent as ever today. Thanks to museums, books, and pop culture, dinosaurs remain larger-than-life. However, some cynics are not so sure that dinosaurs ever existed. A large comet or asteroid hit the earth. Thousands, if not millions of pieces from the asteroid traveled and each hit, one by one while the strong wind and fire from the asteroid wiped out million and millions of dinosaurs. Some did survive but then volcanic eruptions, floods, tsunamis, droughts, wildfires, storms, lack of oxygen, a lot of carbon dioxide, no sunlight and trees caused the dinosaurs to die.

The ground shook. Powerful gusts roiled the atmosphere. Debris rained from the sky. Soot and dust, spewed by the impact and resulting wildfires, filled the sky. That soot and dust then began to spread like a giant sunlight-blocking shade over the entire planet. How long did the darkness last? Some scientists had estimated that it was anywhere from a few months to years. But a new computer model is giving researchers a better sense of what happened. It simulated the length and severity of the global cooldown. And it must have been truly dramatic, reports Clay Tabor. He works at the National Center for Atmospheric Research in Boulder, Colo. As a paleo climatologist, he studies ancient climates. And he and his colleagues have reconstructed a sort of digital crime scene. It was one of the most detailed computer simulations ever made of the impact’s effect on climate. The simulation begins by estimating the climate before the smash-up. The researchers determined what that climate might be from geologic evidence of ancient plants and levels of atmospheric carbon dioxide. Then comes the soot. A high-end estimate of soot totals some 70 billion metric tons (about 77 billion U.S. short tons).
