Think Venus.... Scorched surface and lots of hot gases above it
- bluedevil2k 6y agoThere's no water vapor on Venus though. At a certain point in the atmosphere, wouldn't it be cool enough and pressure low enough to make clouds still? Maybe they move around the Earth to the cool side away from the Sun?
- ben_w 6y agoWater disassociates into hydrogen and oxygen in UV light, and hydrogen gas move faster than escape velocity, even at current atmospheric temperatures. Ok, so it is more complicated than that, the speed of any atom or molecule is a Maxwellian distribution, but enough move fast enough that it’s an acceptable approximation, especially over these time scales.
