Current Affairs MCQs for UPSC & State PSC Exams

Q1:

Assertion (A):
Melting glaciers can lead to an increase in volcanic eruptions.

Reason (R):
The reduction in ice mass over volcanoes decreases pressure on underground magma chambers, making it easier for magma to reach the surface.

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.

Show

Answer: A

Explanation:

Assertion (A): True. Recently, scientist established between melting glaciers and increased volcanic activity, particularly because the pressure dynamics of magma chambers change as ice melts.

Reason (R):
True. The reason provided is scientifically accurate. Ice sheets exert immense pressure on the Earth's crust, including volcanic structures. When glaciers melt, this pressure is relieved, allowing magma that was previously suppressed to rise more easily, which can trigger volcanic eruptions.

The reason directly explains the assertion. The process of depressurization due to ice melt is the mechanism that connects glacial melting to an increase in volcanic activity. Hence, R is the correct explanation for A.
