Which outcome consistently follows increased crustal downwarping above subduction zones?

💡 Explanation

Increased crustal downwarping intensifies pressure and temperature, thus water is released; this then triggers flux melting of the mantle wedge. The increased melt production leads to more volcanism, therefore increased flux melting better explains this process rather than isostatic rebound due to ice melting.
