Which atmospheric component is deeply connected with both Earth heat balance and the water cycle?
Answer and explanation
Correct answer: Water vapour
The governing concept is the dual role of water vapour. It is the main naturally occurring greenhouse gas, so its absorption and emission of infrared radiation influence Earth’s heat balance. It also moves through evaporation, condensation, cloud formation, and precipitation, making it central to the water cycle. Helium, neon, and argon are minor noble gases and do not play comparable roles in either process. Hence option A is correct.
