Which statement is most suitable for the thermosphere?
Answer and explanation
Correct answer: Temperature can rise greatly with height in it
The governing concept is the temperature trend caused by absorption of high-energy solar radiation. In the thermosphere, sparse gases absorb energetic ultraviolet and X-ray radiation, so measured temperature can increase greatly with altitude even though the air is too thin to feel hot in the ordinary sense. Thus option A is correct. Most rain and water vapour occur in the troposphere, which is also the lowest layer.
