Quizplus · Accepted Answer

Most scientists believe that the mass extinction of the dinosaurs, which occurred approximately 66 million years ago, was primarily caused by a catastrophic meteorite impact. This event led to significant environmental changes, including a "nuclear winter" effect that drastically altered the Earth's climate. Evidence supporting this theory includes the discovery of a layer of iridium-rich clay around the world, which is uncommon on the Earth's surface but abundant in asteroids, and the Chicxulub crater in the Yucatan Peninsula, which dates to around the same time.
