Which outcome is associated with hydration melting during subduction?

A)Island arc volcanism increases
B)Seafloor spreading accelerates
C)Continental rifting decelerates
D)Glacial isostatic rebound declines

💡 Explanation

Island arc volcanism will increase because subducting oceanic crust releases water into the mantle wedge, resulting in flux melting; therefore, magma generation increases, rather than other tectonic processes responding.
