According to the presumption based on the theory that "meteorite strikes are a widespread geological process in the solar system" and the comparative planetology, those geological structures of ringed mountains are the relics of earlier meteorite strikes distributed on the earth, which is the natural landscape formed in the interaction between the celestial bodies and the surface terrane when the former fell down on the earth and struck the latter.
