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 mechanism causes ventifact formation enhancement from airborne particles?
• Which outcome occurs when glacial sediment is efficiently lifted far away over land, followed by "frost shattering"?
• Which erosional consequence results when fan sediment supply diminishes?
• Which event results from thawing permafrost causing differential ground subsidence beneath Arctic pipelines?
