Which volcanic outcome characterizes subduction beneath continental crust?

💡 Explanation

Stratovolcanoes form due to flux melting of the mantle wedge during subduction because the subducting plate releases water, which lowers the mantle melting point; therefore, stratovolcanoes result, rather than shield volcanoes caused by hot spots.
