UPPCS · Question 33

Given below are two statements, one labelled as Assertion (A) and the other as Reason (R). Assertion (A): Agra and Darjeeling are located on the same latitude but the temperature of January in Agra is 16 degrees C whereas it is only 4 degrees C in Darjeeling. Reason (R): Temperature decreases with height and due to thin air, places in the mountains are cooler than places in the plains. Select the correct answer using the code given below.

  1. (A) is true but (R) is false
  2. Both (A) and (R) are true and (R) is the correct explanation of (A)
  3. (A) is false but (R) is true
  4. Both (A) and (R) are true but (R) is not the correct explanation of (A)
Show answer & explanation

Answer: (B) Both (A) and (R) are true and (R) is the correct explanation of (A)

Explanation

Both are near 27 degrees N, but Darjeeling's altitude (~2,000 m) makes it far colder, explained by the lapse rate.
