Impact Craters on Earth|
Like the Moon, Earth once was bombarded by meteorites leaving large impact craters. Most of Earth's craters have been erroded away by wind, rain, glaciers and other geological activity. Still more than 100 impact structures have been found on Earth.
One of the most notable meteorite structures on Earth is Meteor Crater, Arizona
Meteor Crater, AZ
Meteor Crater formed about 50,000 years ago. Scientists now estimate that the crater formed from a cloud of iron meteorites striking the Earth at about 12 km per second. About 20 miles west of Winslow Meteor Crater is nearly a mile accross and one of the most obvious impact structures on Earth.
