Question

Assertion(A): Earthquake occurs due to the movement of tectonic plates.
Reason(R): When tectonic plates compress each other, pressure is built up.

• 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

Answer 1

The correct option is A Both A and R are true and R is the correct explanation of A

When two tectonic plates compress each other, there is a significant amount of pressure originating between them. This pressure is released when one of them slides over the other. This release in pressure manifests as an earthquake.
So both the assertion and reason are true. Also the reason is the correct explanation of the assertion.
