Which volcanic outcome results following increased magma hydration?

💡 Explanation

Increased magma hydration enhances volatile exsolution which causes explosive volcanism via **vesiculation**; because dissolved water flashes to steam, it significantly increases internal pressure leading to fragmentation, therefore explosive potential rises rather than lava flow because viscous resistance increases.
