Summary

Evolution by bombardment?

From Michael Prather nebula or, later, the solar wind. That source is generally believed to account for Venus' noble gases, but it would predict unacceptable ratios of N/36 Ar and 20Nef22Ne for the Earth. The current A second major premise of Cameron's years) is used by Cameron as evidence of an composition of planetary atmospheres paper is that the Moon formed from the extended period of bombardment and reflects the initial composition of proto- collision of Earth with a planetesimal the atmospheric erosion. This premise planetary material, the mode of planetary size of Mars. He has the size of Mars[1]

Models for early bombardment are chosen examples which may resolve some
