Question

Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): The temperature increases in the troposphere from ground to tropopause.
Reason (R): Ozone absorbs ultra violet radiation in the stratosphere and makes it warm.
In light of the above statements, choose the correct answer from the options given below.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A).
• B. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
• C. (A) is true but (R) is false.
• D. (A) is false but (R) is true.

Hint:

In the troposphere, temperature decreases with height (lapse rate).
In the stratosphere, temperature increases with height (thermal inversion) due to UV absorption by the ozone layer.
Remembering this alternating pattern helps solve atmospheric profile questions quickly.

Answer 1

The Correct Option is D
