Barringer Crater on Earth
Explanation: What happens when a meteor hits the ground? Usually nothing much, as most meteors are small, and indentations they make are soon eroded away. 49,000 years ago, however, a large meteor created Barringer Meteor Crater in Arizona, pictured above . Barringer is over a kilometer across. In 1920, it was the first feature on Earth to be recognized as an impact crater . Today, over 100 terrestrial impact craters have been identified. Recent computer modeling now indicates how some of the Canyon Diablo impactor melted during the impact that created Barringer.
