← GeographyWhich risk increases when fine loess sediment accumulates rapidly?
A)Glacial ice sheet albedo decrease
B)Seismic amplification during earthquakes✓
C)Dissolution rates of karst topography
D)Eutrophication of enclosed water bodies
💡 Explanation
Seismic amplification risk increases because unconsolidated loess soils exhibit resonant frequencies during tremors, amplifying ground motion through S-wave resonance, therefore structural damage increases rather than glacial albedo reduction because surface features are more relevant.
