Which outcome occurs when plate motion stalls following subduction?

💡 Explanation

Isostatic rebound results because the removal of the downgoing slab lightens the crust; therefore, the buoyant lithosphere rises rather than continue subducting. Slab pull ceases rather than promoting volcanism commonly seen with active oceanic subduction.
