Which process primarily influences volcanic land formation at a subduction zone?

💡 Explanation

When an oceanic plate subducts, hydration-induced melting occurs because water released from the subducting plate lowers the melting point of the mantle wedge, generating magma and volcanism. Therefore, hydration induced melting causes volcanism, rather than decompression melting, shear heating, or radioactive weakening.
