IMAGES OF METEOR CRATER
|
The Meteor Crater in the state of Arizona was the first crater to be
identified as an impact crater.
Between 20,000 to 50,000 years ago, a small asteroid about 80 feet
in diameter impacted the Earth and formed the crater.

The crater is the best
preserved crater on Earth and measures 1.2 km in diameter.
For many years, scientists had denied
that there were any impact craters on Earth.
The origin of this crater has been a source of controversy for many
years. The discovery of fragments of the Canyon Diablo meteorite help prove that
the feature was in fact an impact crater.
