Which outcome occurs when wind velocity decreases near dune crests?

💡 Explanation

Saltation decreases because reduced wind speed diminishes the capacity to carry sand grains via 'wind shear' causing deposition; therefore, transport diminishes rather than accelerating the migration or increasing either ventifact or deflation rates.

• Which risk is heightened when coastal upwelling is abnormally reduced due to persistent high atmospheric pressure?
• Which outcome occurs when wind patterns shift displacing an oceanic gyre center?
• Increased coastal erosion occurs when intensification alters gyre currents because of which mechanism?
• Which consequence results when excessive irrigation saturates agricultural soils?
• Along a gradually sloping coastline, which morphological outcome results when wave refraction concentrates energy unevenly due to nearshore bathymetry?
• Which outcome occurs when tectonic activity interrupts thermohaline circulation?
