Description:

This Earth science animation shows middle and high school students how an asteroid that struck the Earth at the end of the Cretaceous period may have caused a mass extinction that killed the dinosaurs. The introduction explains the basis of the asteroid theory of extinction. The animation depicts an artist's conception, presented from space, of an asteroid hitting the Gulf of Mexico and releasing a cloud that prevented sunlight from reaching the Earth. Movie controls allow students to repeat, pause, or step through the animation, which can give students more time to analyze the images. Copyright 2005 Eisenhower National Clearinghouse
