Which statement is most suitable for the upper atmospheric layers?
Answer and explanation
Correct answer: Particles become rarer but radiation and ionisation can become more important
Atmospheric pressure and particle density generally decrease with altitude because the air column above becomes smaller. At the same time, energetic solar radiation has a stronger relative influence in several upper regions, producing ionisation and other special effects. Option A is therefore the best general statement. Upper layers are not denser than the surface, rainfall is not their universal process, and water vapour is concentrated mainly in the lower atmosphere.
