Why can the thickness of the troposphere change with season and latitude?
Answer and explanation
Correct answer: Intensity of surface heating and convection keeps changing
The troposphere is heated mainly from Earth’s surface. Where insolation and surface heating are stronger, air expands, rises, and convection can extend the troposphere to a greater height; where heating is weaker, its vertical extent is generally smaller. Heating patterns vary with latitude and season because solar angle and day length change. Thus option A gives the governing mechanism, while the other choices invoke false causes.
