Question

Assertion (A): The most common cause of earthquakes is the movement of tectonic plates.

Reason (R): The tectonic plates are in constant motion.

विकल्प

• Both A and R are true and R is the correct reason for A.

• Both A and R are true but R is not the correct reason for А.

• A is true and R is false.

• A is false and R is true.

Answer 1

Both A and R are true and R is the correct reason for A.

Explanation:

Earthquakes occur mainly due to the movement of tectonic plates. Since these plates are constantly moving, their interactions cause stress and release energy, resulting in earthquakes. Therefore, the constant motion of tectonic plates directly causes earthquakes.
