Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: Srinagar is colder than Delhi.
Reason R: Srinagar is at a higher altitude as compared to Delhi.
In the light of the given statements, choose the most appropriate answer from the options given below.
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Both A and R are correct and R is the correct explanation of A
Assertion A: Srinagar is colder than Delhi. Correct. Srinagar has cold winters with snowfall and temperatures below freezing, while Delhi's winter is mild by comparison.
Reason R: Srinagar is at a higher altitude as compared to Delhi. Correct. Srinagar lies in the Kashmir Valley at about 1,600 m above sea level; Delhi is on the plains at about 215 m.
Temperature falls with height, by about 6.5°C for every 1,000 m (the normal lapse rate), because the air higher up is thinner and holds less heat. So Srinagar's height is the reason it is colder, and R correctly explains A.
