Which 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.
