Question

Quizplus · Accepted Answer

Both island arcs and Andean type mountains are formed as a result of subduction, where one tectonic plate is forced beneath another plate. In the case of island arcs, volcanic activity occurs as a result of the subduction, and over time, the accumulation of volcanic material can form mountains. Andean type mountains are also formed as a result of subduction, where the oceanic crust is forced beneath the continental crust, resulting in the formation of a chain of mountains.
