Which outcome results when prolonged subduction ceases in a volcanic arc?

💡 Explanation

Isostatic uplift occurs because the removal of the dense, subducting slab causes bouyancy and the crust to rebound upward via isostasy, rather than continued subsidence. Therefore resulting in uplift; rather than sedimentation which would add weight.
