Which outcome is caused by increased mantle hydration?

💡 Explanation

The addition of water deep in a subduction zone lowers the mantle rock's melting point by flux melting, because water weakens the bonds there; therefore, magma generation rates at volcanoes increase, rather than the other outcomes.
