Which consequence results when increased plate subduction rate occurs?

💡 Explanation

Increased rates induce greater water introduction via the subducting slab, and this mechanism, mantle wedge hydration, lowers the mantle's melting point, leading to increased volcanism; therefore, more water saturation occurs rather than reduced vent activity from hydrothermal systems.
