Which mechanism causes regional uplift when a continental plate overrides a younger oceanic plate at a compressional boundary?

💡 Explanation

When a continental plate overrides a younger, buoyant oceanic plate, crustal thickening occurs because the continental crust shortens and stacks, leading to isostatic rebound and regional uplift to restore gravitational equilibrium. Therefore isostatic rebound results, rather than thermal expansion, erosion, or slab rollback which require different density and thermal considerations.
