Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : Increase in average sea surface temperature will contribute towards enhancement of atmospheric CO2 concentration.
Reason (R) : Increase in sea surface temperature increases the solubility of CO2 in ocean water.
In the light of the above statements, choose the most appropriate answer from the options given below :
- A.
Both (A) and (R) are correct and (R) is the correct explanation of (A)
- B.
Both (A) and (R) are correct but (R) is not the correct explanation of (A)
- C.
(A) is correct but (R) is not correct
- D.
(A) is not correct but (R) is correct
Attempted by 15 students.
Show answer & explanation
Correct answer: C
The Assertion (A) is true because warmer ocean waters release dissolved carbon dioxide, increasing atmospheric CO2 concentration. However, the Reason (R) is false because gas solubility in liquids decreases as temperature rises. Therefore, the correct option states that Assertion is true but Reason is false.
