Question

Quizplus · Accepted Answer

Volcanism related to hot spots or divergent margins occur at locations where there is upwelling of magma from the mantle. This occurs at mid-ocean ridges (divergent margins) and hot spots. Hawaii, which is near site C, is a classic example of a hot spot volcano. Site D is a mid-ocean ridge, where new oceanic crust is formed, and volcanism is also associated with it. Sites A and B are on island arcs and the Andes, respectively, which are both associated with subduction zones and volcanism related to convergent plate boundaries. Therefore, choices A, B, and D can be ruled out, leaving only choices C and E. However, E is incorrect because site B is not associated with a hot spot or divergent margin. Thus, the best choice is C.
