Which outcome occurs when subduction beneath an island arc increases sediment influx?

💡 Explanation

Increased sediment influx compacts the accretionary wedge through sedimentary loading, because greater weight from deposited material squeezes water out, therefore increasing density. This results in increased sediment compaction, rather than reduced magma flux or tectonic modifications.
