dune formation

Dune formation occurs when wind transports and deposits loose sand particles across a landscape. As the wind blows, it lifts and moves sand grains, which eventually settle when the wind slows down. When enough sand accumulates in one area, it creates a small hill or mound. Over time, continued wind action shapes these mounds into various dune types, such as crescent-shaped barchans or elongated ridges. Vegetation, moisture, and obstacles can influence dune shapes and stability. Overall, dunes develop through the ongoing process of wind-driven sand transport and deposition, creating dynamic landforms in desert, coastal, and inland environments.
