Temp. too low and atmospheric pressure too low to allow liquid water. Winter ice caps are larger because co2 freezes. Ice sublimes (solid to gas) into atmosphere in summer, shrinking the ice cap. Sky should be black but is not because atmosphere is so thin and wind sirs reddish dust in air. Has largest volcano in solar system, olympus mons. Low gravity, lack of plate tectonics, and mantle plumes allow mountains/volcanoes to form. Maybe a good place to look for life. Noachian (oldest) (4. 5 - 3. 8 billion years ago) Hesperian (intermediate) (3. 8 1 or 2 billion years ago) Minerals formed in presence of water have been found: Found a rock called cumberland with ancient water in it. If all the ice detected melted, mars would be under 11 metres of water. Smaller bodies of water existed but not oceans. Most of atmosphere disappeared 3 billion years ago because:
