Question
Volcanoes form most commonly in regions where one tectonic plate plunges beneath another tectonic plate. How does this process lead to volcano formation?
A.
It causes strong earthquakes, which shake the ground upward into the shapes of volcanoes.
B.
The plate plunging downward suddenly turns upward, breaking through the surface to form volcanoes.
C.
It causes part of the overriding plate to melt into magma, which rises up to form volcanoes at the surface.
D.
The plate plunging downward knocks loose part of the Earth's core, which rises up to form volcanoes at the surface

The correct answer is:
C. It causes part of the overriding plate to melt into magma, which rises up to form volcanoes at the surface.
This process occurs at convergent plate boundaries, where one tectonic plate is forced under another (a process known as subduction). The subducting plate can cause the mantle above to melt, creating magma that may rise to the surface and result in volcanic activity.
