Which outcome occurs when wind exceeds threshold velocity?

💡 Explanation

Sand sheet formation occurs on impact of the **saltation** process when mobilized sand grains bombard the surface, because the increased wind speed lifts the sand; therefore, surface becomes covered instead of stabilization, rather than protecting through desert pavement .

• Which outcome occurs when wind velocity decreases suddenly across desert dunes?
• Which risk escalates when ephemeral stream discharge exceeds capacity on arid-region alluvial fans?
• Which risk increases for communities protected by artificial levees constructed on a meandering river?
• Which outcome is caused by increased volatile exsolution in magmatic domes?
• Which climate outcome in coastal regions results most directly from the ocean's thermal buffering effect?
• Which consequence results when rapid aggradation overwhelms river levees?
