Which mechanism shapes ventifact development given limited dune sand?

💡 Explanation

Aeolian abrasion creates ventifacts where constant wind-driven sand impacts exposed rock surfaces, because the repetitive impact grinds and polishes the rock preferentially, therefore forming distinct facets rather than other weathering patterns.

• Which mechanism causes enhanced surface phytoplankton blooms during coastal upwelling events?
• Which effect is amplified as increased sediment deposition obstructs a river meander and subsequently cuts off river flow?
• Which outcome increases with excessive levee construction along a fluvial system?
• Which phenomenon primarily regulates magma generation during subduction at convergent plate boundaries?
• Which hazard exacerbates sinkhole formation after extreme rainfall?
• Which cave formation process ceases when groundwater oxygen is depleted?
