Which outcome occurs during subduction when plate hydration weakens crustal rock?

A)Formation of an accretionary wedge
B)Decreased mantle plume volcanism
C)Reduced frequency of deep earthquakes
D)Increased plate movement velocity

💡 Explanation

An accretionary wedge forms because the subducting plate releases water, which hydrates and weakens the overlying crustal rocks. This causes material to be scraped off and piled up, therefore forming a wedge, rather than reduced plume activity.
