← GeographyWhich outcome rapidly decreases local albedo when pyroclastic density currents cover glaciers?
A)Increased surface melt rate✓
B)Decreased radiative atmospheric forcing
C)Enhanced ice crystal formation
D)Diminished ablation zone expansion
💡 Explanation
Pyroclastic material darkens the glacial surface, triggering increased surface melt rate because reduced albedo causes absorption of more solar radiation. Therefore, melting intensifies, rather than atmospheric radiative forcing diminishing or crystal enhancement occurring.
