← GeographyWhich increased risk results when poorly compacted loess deposits experience saturation?
A)Increased seismic wave amplification
B)Elevation in the local albedo
C)Sudden surface subsidence and collapse✓
D)Accelerated chemical weathering reactions
💡 Explanation
Increased saturation in loess can initiate hydrocompaction, reducing its volume and bearing capacity; therefore, infrastructure can experience catastrophic settlement, rather than other processes because the loess structure loses its strength rather than triggering atmospheric or radiative phenomenon.
