← GeographyWhich volcanic outcome results following increased magma hydration?
A)Increased explosive eruption potential✓
B)Effusive lava flow creation
C)Decreased caldera formation likelihood
D)Reduced stratovolcano flank instability
💡 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.
