When a high-speed object strikes a surface, it produces an enormous amount of energy. This is called kinetic energybecause it is caused by motion. The amount of energy produced in this way depends on the mass of the impacting object and the velocity with which it strikes the surface: where m is the mass of … See more Every body in the solar system has been subjected to the impact of objects such as comets, asteroids, or accretionary debris. The Moon, Mars, and Mercury all have heavily cratered … See more In general, impact craters have a raised rim with the floor at a much lower level than the surrounding terrain. Fresh craters are surrounded by low, hilly terrain and swarms of small … See more WebImpact cratering is a pervasive geologic process that continually modifies the martian surface.
