Which outcome occurs when increased sediment loading affects marine trench subduction zones?

💡 Explanation

Mantle wedge melting decreases because subducted sediment reduces melt-generation efficiency. Introduction changes the volatile and thermal fluxes; therefore melt production declines, rather than causing increased melting caused by other factors.
