Text, Did You Know? Impact Craters
In an animation, the Earth turns. Text, There are nearly 200 confirmed impact craters on Earth's surface.
Impact craters form when meteorites - rocks from space - strike Earth's surface and explode.
Simple Crater, Some impact craters are relatively small, young, and fresh, with simple bowl-like shapes. Barringer Crater (Meteor Crater), Arizona, 50,000 years old.
Lonar Crater, India, 35,000 - 50,000 years old
Tenoumer Crater, Mauritania, 20,000 - 1.6 million years old
Complex Crater. Others are larger, older, buried, and more eroded, with more complex structures. Tin Bider Crater, Algeria, 70 million years old
Aorounga Crater, Chad, 350 milion years old
Shoemaker (Teague) Impact Structure, Western Australia, 1.6 billion years old
