Which outcome frequently occurs when a continental plate overruns a hydrated oceanic plate?

💡 Explanation

When hydrated oceanic crust subducts, dehydration reactions in the downgoing slab release water into the mantle wedge above, reducing its melting point and inducing flux melting; therefore, magma creation and subsequent volcanism results, rather than crustal deformation or reduced tsunami risk.
