07. How hot and dry is Venus? (A K2S Question)

From The Space Library

Jump to: navigation, search

The mean surface temperature on Venus is 867.2° F. Venus may have originally had as much water as Earth; but, with continuous heating, water vapor was split into hydrogen (which escaped into space) and oxygen (which combined with the rock). Because of their dryness, Venus's rocks are much harder than Earth's, which leads to steeper mountains, cliffs and other features.
