Why are most weather elements confined to the troposphere?
Answer and explanation
Correct answer: Because water vapour, dust and surface heating are most effective here
The governing concept is that weather requires moisture, dust particles and heating-driven convection. The troposphere is directly warmed by Earth’s surface, contains most atmospheric water vapour and has vigorous vertical mixing, so clouds, rain and winds form there. The exosphere is extremely thin, while options C and D contradict the actual composition and presence of air. Therefore, option A is correct.
