How is venus' atmosphere different from earth's? Surface temperature and pressure are much greater and the temperature drops rapidly. The upper of the atmosphere
is much colder than earths but the lower is hotter than earth's.

Why is there no liquid water on venus? The surface is so hot it would cause any water to boil away. Extreme heat slowly evaporated the water and strong solar winds stripped the molecules from Venus.

Why do scientists think there used to be water on venus? Earth and Venus were formed the same way and they got water from the rocks and the commets.
