Which outcome occurs when increased sediment accumulates above a subducting slab?

💡 Explanation

Decreased trench rollback occurs due to sediment deposition altering the buoyancy and friction, therefore, resisting the slab's descent rate, rather than directly increasing melt production or earthquake patterns; this process is called tectonic erosion.
