Lunar Orbiter: Impact Crater Geology - Lunar and Planetary ...

Impact craters are produced by the collision of a meteorite or comet with the surface of the Moon, which ejects material and leaves behind a crater. Small craters, less than about 15 kilometers in diameter on the Moon, have a relatively simple, bowl-shaped morphology.

Why study impact craters? AMNH

2021-8-28  The Planetary Deep Past Impact craters allow scientists to study a planet’s geological history—even when the records are buried beneath the surface. During an impact, buried material is ejected while outward pressure pushes the rock at the crater’s edge upward, forming a rim.

craters - Solar System Exploration Research Virtual Institute

...asins on the moon, dating to about 3.9 billion years ago, bear witness to this bombardment. “When the Apollo astronauts brought back samples, it was quickly realized that all the circular features up there were in fact impact craters,” says David Kring of the Lunar and Planetary Institute. Moreover, the ages of a large variety of moon ...
