Which of the following specialized desert landforms is formed by the accumulation of wind-blown silt particles over extensive areas, creating fertile soil deposits known for vertical cleavage and high agricultural productivity, prominently seen in northern China and parts of Central Europe?

💡 Solution & Explanation

Loess is an aeolian sediment formed by the accumulation of wind-blown silt, typically originating from glacial outwash plains or desert margins, characterized by homogeneous texture, lack of stratification, and vertical cliff-forming stability. Barchan dunes are crescent-shaped sand dunes formed in areas of unidirectional winds. Ergs are vast sand seas found in hyper-arid deserts. Pediments are gently inclined rock-cut erosion surfaces at the foot of retreating mountain fronts.
