If a question discusses seasonal change in tropospheric thickness, what is the most appropriate explanation?
Answer and explanation
Correct answer: Heating and convection intensity change with season
The thickness of the troposphere is not identical everywhere or in every season. Seasonal heating changes air temperature, expansion, vertical motion, and convection; stronger warming can make the troposphere extend to a greater height, while colder conditions can reduce its thickness. Thus option A provides the appropriate physical explanation. Gravity does not disappear, the exosphere does not descend to the surface, and pressure never becomes equal at all heights simply because the season changes.
