Question

Quizplus · Accepted Answer

When two oceanic plates collide and one is older and cooler (more dense) than the other, the denser plate will subduct beneath the less dense plate. This process results in the formation of a deep oceanic trench. As the plate subducts, it releases water which leads to the formation of magma in the overlying mantle. This magma rises and can lead to the formation of volcanic island arcs.
