← GeographyWhich risk increases when pyroclastic flow encounters meltwater?
A)Lahars form rapidly downstream✓
B)Shield volcano magma chamber recharge
C)Volcanic ashfall particle size decreases
D)Vog intensity decreases near vent
💡 Explanation
Lahars become highly probable due to rapidly bulking flows because pyroclastic flow introduces heat causing turbulent mixing and entrainment; therefore increasing lahar intensity, rather than impacting other described volcanic parameters.
