Which risk increases when glaciers recede and drain lakes?

A)Rapid glacial-lake outburst floods✓

B)Localized stratospheric ozone depletion

C)Increased volcanic eruption frequency

D)Accelerated continental plate subduction

💡 Explanation

Glacial retreat leaves unstable moraine dams that can fail during a glacial-lake outburst flood because hydrostatic pressure exceeds moraine strength; therefore, catastrophic flooding is more probable in downstream areas, rather than other geophysical risks unrelated to the ice melt.
