Assertion (A): Thickness of the troposphere is the greatest at the equator.
Reason (R): Near the equator insolation is high and convection currents are strong.
Both A and R are true and R is the correct explanation of A
Correct AnswerBoth A are R is true and R is not the correct explanation of A
Incorrect AnswerA is true but R is false
Incorrect AnswerA is false but R is true.
Incorrect AnswerExplanation:
Both A and R are true and R is the correct explanation of A
The troposphere is thinner at the poles and thicker at the equator. The average thickness of the tropical troposphere is roughly 7 kilometers greater than the average tropospheric thickness at the poles because the equator is warmer. Heat differential on the planet's surface causes convection currents to flow from the equator to the poles. This implies that the warmer the weather, the thicker is the troposphere.
