If the equatorial tropopause is higher than the polar tropopause, what is the most suitable reason?
Answer and explanation
Correct answer: Greater heating and deeper convection in the equatorial region
The governing concept is the effect of heating and convection on tropopause height. Stronger solar heating near the equator warms the surface and lower atmosphere, making air rise through deeper convective columns. This expanded, vigorously rising air places the tropopause at a greater altitude than in the colder polar region. The stratosphere is not absent at the poles, gravity does not disappear, and ozone is not completely absent there. Therefore, A is correct.
