Question

Which processes are important in the formation of volcanic arcs at the edge of continental plates? Select the two correct answers

GPT-5 mini · Answer

- Subduction of an oceanic plate beneath the continental plate (convergent plate boundary)
- Flux-induced partial melting of the mantle wedge above the subducting slab (water and volatiles released from the slab lower the mantle solidus and generate magma)

Briefly: the down-going oceanic lithosphere carries hydrated minerals that release water as it heats; that water lowers the melting point of the overlying mantle, producing magma that rises through the continental crust to form the volcanic arc.
