← GeographyAccelerated thermokarst formation results when which mechanism prevails?
A)Organic matter decomposition increases
B)Freeze-thaw cycles decrease
C)Snowfall duration decreases
D)Surface albedo values decrease✓
💡 Explanation
Decreased surface albedo increases net radiation absorption, therefore amplified thaw induces subsidence driven by thermokarst formation because the latent heat needed overcomes conductive cooling, rather than reduced decomposition effects.
