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.

• Which atmospheric effect intensifies when the subtropical high-pressure zone descends, compressing air within Hadley cells?
• Which outcome is intensified as the hydrological cycle experiences stronger Coriolis effect?
• Which process limits dissolved oxygen level when coastal upwelling reverses direction offshore?
• Which process favors the long-range transport of loess?
• Which outcome is more likely when floodplain levees subside unevenly?
• Which geological consequence results when differential stress exceeds rock strength along a transform fault?
