Multiple choice

Directions: The following items consist of two statements, one labelled as Assertion (A) and the other labelled as Reason (R). You are to examine these two statements carefully and decide if the Assertion (A) and the Reason (R) are individually true and if so, whether the reason is a correct explanation of the Assertion. Select your answer to these items using the codes given below. Assertion (A) : Circum pacific belts accounts for major percentage share of world`s total earthquakes of varying magnitude and deep focus. Reason (R) : Maximum occurrence of earthquakes along circum-pacific belt is caused by divergent motion of tectonic plates and consequent formation of faults.

  1. Both A and R are true and R is the correct explanation of A.

  2. Both A and R are correct but R is not the correct explanation of A.

  3. A is true but R is false.

  4. A is false but R is true.

Explanation

The Circum-Pacific Belt is the world's most active earthquake zone, but this activity is caused by convergent plate boundaries and subduction, not divergent motion. Divergent boundaries, where plates move apart, are typically associated with mid-ocean ridges and less intense seismic activity.
