Question

Assertion (A):
Margins of Pacific ocean see unique pattern of volcanoes and earthquakes.
Reason (R):
Pacific ocean forms a single entity with respect to Earth's movement and stability.

In the context of Sea floor spreading theory, which one of the following is correct?

• A. (A) is false, but (R) is true
• B. (A) is true, but (R) is false
• C. Both (A) and (R) are true, but (R) is not the correct explanation of (A)
• D. Both (A) and (R) are true and (R) is the correct explanation of (A)

Answer 1

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

Pacific ocean forms single entity moving as a single piece thus observes ring of volcanoes and earthquakes around the margins. In later theories we will observe the existence of Pacific plate.
