← GeographyWhich outcome is accelerated during subduction with serpentinization?
A)Mantle wedge melting increases dramatically✓
B)Trench rollback rate will sharply decrease
C)Oceanic crust density rises considerably
D)The overriding plate stabilizes considerably
💡 Explanation
Increased water weakens mantle rock; flux melting increases because serpentinization introduces water, therefore mantle wedge melting increases drastically, rather than rollback slowing or the overring plate staibliizing since this relates more to the pressure dynamics itself.
