Question

Volcanic eruptions along the west coast of North America are due to A) hotspot plume activity in the mantle. B) divergent plate boundaries resulting in a spreading ridge. C) collision zones that result in mountain building. D) convergent plate boundaries where subduction occurs and generates melts. E) transform plate boundary where plates slide past one another.

Answer 1

Volcanic eruptions along the west coast of North America are due to convergent plate boundaries where subduction occurs and generates melts. The correct answer ia option D.

Step-by-step explanation:

Volcanic eruptions along the west coast of North America are due to D) convergent plate boundaries where subduction occurs and generates melts. When two tectonic plates collide, the denser oceanic plate is forced beneath the lighter continental plate, creating a subduction zone. The heat and pressure from the subduction process cause melting in the Earth's mantle, leading to volcanic activity.
