← GeographyWhich process primarily influences volcanic land formation at a subduction zone?
A)Decompression melting of the mantle
B)Hydration-induced melting of the mantle✓
C)Shear heating within a transform fault
D)Radiometric weakening of continental crust
💡 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.
