Which risk strongly increases due to differential weathering when loess deposits overly bedrock?

💡 Explanation

Gully erosion increases because 'piping', a subsurface erosion mechanism, weakens loess above less permeable bedrock; therefore, surface collapse occurs rather than uniform denudation patterns across soil layers.
