Meteorite crater. Aerial view of the Wolf Creek meteorite crater on the edge of the Great Sandy Desert, Western Australia. The crater was formed when a meteorite weighing thousands of tonnes collided with the Earth between 1-2 million years ago, in the Pleistocene period. It exploded with the force of an atomic bomb, producing a crater with a diameter of 853 metres. The shape of the crater (a near perfect circle) is well preserved, as only very slow weathering processes occur in arid environments. (KEYSTONE/SCIENCE PHOTO LIBRARY/Bernhard Edmaier) === ===
