← GeographyWhich outcome results when hydraulic action on loess?
A)Formation of gullies and ravines✓
B)Development of exfoliation domes
C)Stratification becomes visibly more defined
D)Increased silica cementation between particles
💡 Explanation
Gullies form because loess's loosely packed silt is vulnerable to erosion by hydraulic action, leading to vertical incision of the landscape (gullying), therefore gullies result, rather than silica cementation due to the lower clay amount.
