Formation of an impact crater
						� Crater caused by the explosion � Impactor is melted, perhaps vaporized �by the kinetic energy released � Temporary �transient� crater is round � Gravity causes walls to slump inward forming �terraces� � Movement of material inward from all sides (trying to fill in the hole) may push up central peak in the middle. � Final crater is typically ~10 times �the size of the impactor
