← GeographyWhich outcome occurs when accumulated sediment compacts during subduction?
A)Orogenic belt stress release
B)Accretionary wedge formation✓
C)Asthenosphere magma upwelling
D)Hydrothermal vent deactivation
💡 Explanation
An accretionary wedge forms because sediment is scraped off the subducting plate, building a mass of deformed material. This causes formation, therefore excess material accretion rather than material release, due to overburden.
