WebSmall, meter-sized craters form much more frequently than large, kilometer-sized craters. After crater formation, craters start to widen, fill in, and their topographic relief is reduced due to their exposure to the lunar environment. Eventually, this infilling process is sufficient to render craters unrecognizable on the surface. WebOn the evolution rate of small lunar craters.
