Sand dune origin, transportation force
The sand dunes were mainly formed by the wind. The wind could push and move the sand to form sand dunes. The formation of sand dunes required a dry climate, so that the sand was loose and could not be consolidated. It could be transported and moved by the wind. There was usually a dominant wind direction in the desert. Under the push of the wind, the sand on the windward side rolled along the wind direction, crossed the top of the sand dune, and slid down the back. The sand that slid down kept accumulating, moving, and sliding down. This continued to move, forming moving sand dunes. The sand on the windward side of a single sand dune moved forward with the wind, so the surface was generally longer and the slope was slower. After passing the top of the sand dune, it slid down under the effect of gravity, so the sliding bottom was relatively steep. Through these characteristics, one could determine the dominant wind direction. In addition to wind transportation, water could also transport and sort particles. For example, seawater, river water, and lake water could be deposited on the shore or shallow water to form a beach. In short, the sand dunes were the result of the movement of wind and water.
Sand dune origin
The sand dunes were formed by the accumulation of wind. Sand dunes were usually associated with desert areas where the wind blew sand over a large area. The sand was pushed by the wind, and the sand on the windward side continued to slide over the top of the sand dunes, causing the sand to move continuously, thus pushing the sand dunes forward. The formation of sand dunes also required dry climate conditions and rich desert materials. The existence of sand dunes was inseparable from drought and wind. Specifically, sand dunes were formed by the wind moving unconsolidated materials, and the source of sand dunes could be fine-grained materials from various ancient or modern deposits.
Sand dune origin analysis
The sand dunes were formed by the accumulation of wind. The Danniang Sand Dunes in the Grand Canyon of the Yarlung Zangbo River were dry in winter and spring every year, and the wind was strong. In addition, the vegetation was thin, so the wind was less blocked by the river surface, forming a vortex updraft, which carried the sand on the sandbar and the floodplain. It was blocked by the mountainous terrain by the river, and the wind speed slowed down. The sand piled up on the hillside and accumulated over time to form sand dunes. The sand of the dunes mainly came from the nearby sandbars and floodplains. The formation of sand dunes was inseparable from the effects of drought and wind.
