Which mechanism accounts for the formation of island arcs at convergent plate boundaries?

💡 Explanation

Continuous subduction causes flux melting because the subducting plate releases water into the mantle wedge, lowering its melting point, leading to magma generation and subsequent volcanism and forms island arcs. Therefore, subduction induced melting results, rather than plume upwelling, crustal extension or hotspot volcanism, none of which specifically dependent on plate convergence.
