← GeographyWhich consequence results when increased glacial flour deposition onto loess?
A)Enhanced soil stabilization with moisture
B)Decreased aggregation, lower water retention✓
C)Increased soil porosity and drainage
D)Accelerated vegetation growth from nutrients
💡 Explanation
Increased flour on loess leads to soil instability because glacial sediment addition disrupts existing soil particle aggregation; the introduced silt grains fill voids rather than promoting structuration, therefore reducing water retention rather than improving soil stability.
