Which outcome occurs when a continental plate overrides a subducting oceanic plate lacking buoyant features?

💡 Explanation

A volcanic arc forms due to flux melting. Water released from the subducting slab lowers the mantle's melting point, because asthenospheric mantle melts and ascends, therefore generating a volcanic arc on the overriding continental plate, rather than rifting or purely strike-slip motion.
