Which outcome is primarily caused by mantle upwelling when a subducting plate stalls?

💡 Explanation

A stalled subducting plate impedes slab rollback, causing upper mantle material to flow around the obstruction as corner flow; this divergence induces extensional forces and therefore creates a back-arc spreading basin, rather than increasing volcanism far above.
