Q. Given below are two statements, one is labelled as Assertion (A) and the other as Reason (R).
Assertion (A): The Himalayas are still rising.
Reason (R): The Indian tectonic plate is colliding with the Eurasian plate.
Select the correct answer from the codes given below.
a) Both (A) and (R) are true, but (R) is not the correct explanation of (A).
b) (A) is false, but (R) is true.
c) Both (A) and (R) are true and (R) is the correct explanation of (A).
d) (A) is true, but (R) is false.
Question from UPPSC Prelims 2024
Correct Answer: c) Both (A) and (R) are true and (R) is the correct explanation of (A).
Explanation:
– Assertion (A): The Himalayas are still rising.
This statement is true. The Himalayas are geologically young mountains and are still rising due to tectonic activity.
– Reason (R): The Indian tectonic plate is colliding with the Eurasian plate.
This statement is also true. The Indian plate is moving northward and colliding with the Eurasian plate, causing the crust to buckle and fold, which leads to the uplift of the Himalayas.
– Relationship between (A) and (R):
The collision of the Indian and Eurasian plates is the primary reason for the continuous rise of the Himalayas. This tectonic activity causes the mountains to grow in height over time. Therefore, (R) is the correct explanation of (A).
Thus, the correct answer is c) Both (A) and (R) are true and (R) is the correct explanation of (A).
