Which agricultural outcome results from cyclical wind erosion of loess?

💡 Explanation

Wind erosion selectively removes fertile topsoil and organic matter via **deflation**, because finer particles within loess are more susceptible. This reduces downstream soil fertility and crop productivity, rather than benefiting other regions via increased deposition.

• Which outcome occurs when localized wind shear increases overland?
• Which mechanism causes the aridity observed on the leeward side of mountain ranges bordering major river streams?
• Which landscape change results when carbonic acid is added to karst regions?
• Which risk increases following increased freeze-thaw cycles on granite?
• Which outcome arises when weakened trade winds reduce upwelling off South America during an El Niño event?
• Which process leads to copper deposit concentration within alluvial fans?
