What would have happened if there was no atmosphere?
What would have happened if there was no atmosphere? Eventually (long after surface life had died), solar radiation would break atmospheric water into oxygen, which would react with carbon on the Earth to form carbon dioxide. The air would still be too thin to breathe. The lack of atmosphere would chill the Earth’s surface. Plants […]
