Impacting Extraterrestrials Scar Planetary Surfaces describes how comets or asteroids shape the surface of Earth and other bodies in the solar system. A sequential cross-sectional diagram illustrates the formation of a simple crater. Notable examples of impact craters include the Barringer Crater in Arizona and the Chicxulub impact crater on the Yucatan Peninsula, which may be related to the extinction of the dinosaurs.
