Threats from space
Meteor Crater, also known as the Barringer Meteorite Crater, located near Winslow, Arizona, USA. The crater was made 49 000 years ago when a 10 000 000-tonne meteor impact dislodged 300 000 000 tonnes of rock. This classic photo of Meteor Crater was taken by David Roddy of the United States Geological Survey.
