Craters with stepped terraces on the interior wall, a flat floor, and a single peak or group of peaks in the center. The interior wall terraces, which form due to landslides, result in a shallower overall inclinationAngle between the plane of an object's orbit and the ecliptic; the inclination of a moon's orbit is the angle between the plane of its orbit and the plane of its primary's equator. of the wall than in simple craters. The exterior rims are similar in appearance to simple craters. The photograph shows King CraterBowl-like depression ("crater" means "cup" in Latin) on the surface of a planet, moon, or asteroid. Craters range in size from a few centimeters to over 1,000 km across, and are mostly caused by impact or by volcanic activity, though some are due to cryovolcanism. on the far side of the Moon, a typical lunar complex crater, which is 93 km in diameter and ~5 km deep. The central peaks are ~2 km high.
