True

False

Explanation / Answer

Answer 25:

False, because the earthquake are mostly generates in subduction zones which is the collision point of ocean and continent. And epicenter is the vertical above point on the surface of plate from focus.

Answer 26:

True, because hotspots are originates from lower mantle.

Answer 27:

False, the first rupture underground point is focus.

Answer 28:

True, explaination given in question itself.

Answer 29:

False, in normal faulting hanging wall moves downward with respect to footwall.

Answer 30:
