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

💡 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.
