Which risk increases as aeolian dune crests steepen?

💡 Explanation

Gravity-driven slump risk increases because exceeding the angle of repose results in slope failure rather than stable accumulation. Grain overturning events shift sediment downslope; therefore, exceedance causes slumps, rather than deflation or erosion.

• Which outcome occurs when rapid sediment deposition obstructs alluvial channel flow?
• Which outcome is directly intensified by the Rossby wave effect on continental interiors?
• Which climatic effect results when volcanic aerosols drastically increase Earth's albedo?
• Which consequence results when rapid levee construction on the Mississippi restricts floodplain access?
• Which ecological consequence results when a persistent high-pressure system reduces coastal upwelling along the California coast?
• Which outcome occurs when the uplift rate reduces in a landscape containing alluvial fans?
