Why is it that sublimation leaves a different “geography” than melting ? At a gross level, melting would also give a certain small amount of “erosion” which would increase the smoothing , but I think sublimation being temperature dependent and acting over the whole surface, would leave a more rounded surface than what appears to be the case.
