Which primary outcome results when increased subduction increases mantle wedge hydration?

💡 Explanation

Increased mantle hydration through water flux in subduction zones lowers magma viscosity and increases volatile content; therefore explosive eruption intensity increases occur rather than trench sediments lessening, because flux melting dominates impacts there.
