Volcanic rocks, mostly _______, accumulate near a convergent plate boundary.

Question

Quizplus · Accepted Answer

Andesites are volcanic rocks that are commonly associated with convergent plate boundaries, where two tectonic plates are colliding. This is because the magma that forms andesites is generated as oceanic crust is pushed beneath continental crust in a process called subduction. As the oceanic crust sinks deeper into the mantle, it heats up and begins to melt, producing magma that rises to the surface and solidifies into andesitic rocks.
