Question

Quizplus · Accepted Answer

The magma that fuels and produces volcanic activity around the Pacific Ring of Fire is derived from the rise of material that was melted in subduction zones along the Pacific margins. Subduction zones occur when one tectonic plate moves beneath another, causing the lower plate to melt and form magma. This magma then rises to the surface, creating volcanic activity. The Pacific Ring of Fire is known for its volcanic activity because it is located along the boundaries of several tectonic plates, including the Pacific Plate, which is subducting beneath several other plates.
