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. Early this morning, the
Leonid Meteor Shower reaches its peak,
although no impacts of this magnitude are expected.
