← GeographyWhich deep-sea trench feature is enhanced during subduction?
A)Accretionary wedge sediment accumulation✓
B)Abyssal plain sediment stabilization
C)Hydrothermal vent mineral precipitation
D)Seamount chain coral reef development
💡 Explanation
Accretionary wedges grow at subduction zones because plate convergence scrapes sediment off the down-going plate, leading to sediment accumulation. Therefore, the wedge size increases; rather than abyssal stabilization which resists change, and vent/reef options which reflect chemical/biological processes.
