Which risk to alpine glaciers increases when volcanic ash accumulates?

A)Decreased albedo, increased melting rate✓

B)Increased strength, reduced crevassing

C)Increased volume, accelerated glacial advance

D)Enhanced ablation zone, stabilized ice flow

💡 Explanation

Reduced albedo occurs because ash darkens the ice, increasing solar energy absorption, driving accelerated melting (ablation), rather than enhancing stability or glacial advance; therefore, melting increases due to this positive feedback.
