Question

Quizplus · Accepted Answer

The formation of a magmatic arc is commonly associated with ocean-continent convergence and results in the formation of volcanic islands such as the Aleutian Islands. Choice A (mantle diapir) and B (convection uplift) are not directly associated with ocean-continent convergence, while choice C (abyssal plain) is a feature of the ocean floor not formed by magmatic processes. Choice E (hot spot) is usually associated with mantle plumes and not ocean-continent convergence.
