← GeographyWhich outcome contributes to loess formation after glacier retreat?
A)Glacial abrasion yielding rock flour✓
B)Dissolution enhances chemical weathering rates
C)Vegetation colonizes exposed bedrock quickly
D)Rapid soil horizon development stabilizes soils
💡 Explanation
Glacial abrasion produces fine silt, called rock flour, transported by wind; Aeolian Transport sorts the sediment. This creates loess deposits because glacial abrasion generates substantial silt, rather than alternate weathering and soil stabilization outcomes.
