← GeographyWhich consequence results when loess sediment is exposed to sustained surface runoff?
A)Progressive gullying and badland topography✓
B)Reduced porosity and increased compaction
C)Accelerated mineral weathering and oxidation
D)Enhanced preservation of paleosol horizons
💡 Explanation
Gullying develops because loess' open structure makes it highly erodible. Piping erosion removes subsurface material thereby leaving behind channels. This progressive channel incision leads to badland topography rather than compaction therefore.
