← GeographyWhich outcome typically results from higher volatile content within magma?
A)Increased explosive eruption likelihood✓
B)Decreased viscosity of emitted lava
C)Reduced pyroclastic fragment density
D)Elevated lava flow propagation velocity
💡 Explanation
Higher volatile content increases gas escape pressure, promoting fragmentation and violent eruptions due to Vesiculation. This intensifies explosive eruption likelihood, rather than creating effusive flows because expanding gas disrupts the magma structure.
