Question

Scientists expected venus to have a large amount of water. however, little detectable water has been found anywhere on venus, either on its surface or in its atmosphere. water, like carbon dioxide, is a greenhouse gas. what is not a reason for venus to now be so dry?

Answer 1

The reason that says that Venus should have had water from the sources the same as the Earth, but all of those are gone is not a correct reason why Venus is dry. Venus is the hottest planet in the solar system because of the atmosphere it has. The atmosphere of Venus contains 95% of CO2 causing it be hot and  dry.
