Thousands of small lobate fault scarps are found just about everywhere in the lunar highlands, and are formed when contractional forces break the crust and thrust blocks upward. Here a lobate scarp cuts across and deforms a large impact crater (about 5 km in diameter). The vast, global array of such young fault scarps is evidence that the Moon is shrinking as it liquid core freezes to a solid and the interior cools thus taking up less space. These faults are not ancient, they are very young – so young the Moon is likely slowly shrinking today.
