Why is the tropopause higher over the equator than over the poles?
Answer and explanation
Correct answer: Heating and convection are stronger near the equator
Option A is correct. The equator receives more nearly direct solar heating, so the surface and lower atmosphere become warmer. Strong convection then carries air upward through a greater depth before the stable tropopause is reached, making the tropopause higher. At the poles, weaker heating produces less vigorous convection and a lower tropopause. The Sun is not always overhead at the poles, gravity does not disappear at the equator, and ozone is present near both regions; therefore B, C, and D are false.
