Document Summary
Habitable zone (cid:224) the habitable zone is the range of distances from the sun within which we could in principle move our planet without fundamentally changing the characteristics that make it home to abundant life: based on the range of distances at which worlds similar to earth could exist, simply being in a star"s habitable zone is not enough to make it habitable, habitable zones evolve with time. Why is it"s atmosphere so much different than earth 2 possible reasons: the abundance of carbon dioxide on venus, both planets have about the same amount of co2, but earth is stored in carbonate rocks or in oceans, venus lacks a similar cycle to earth"s carbon cycle because it has no liquid water in which carbon dioxide can dissolve, the lack of water on venus, venus is too hot for either ice or water, two possible explanations for the lack of water.
