How are the stripes on the surface of the sand dune formed?
The stripes on the surface of the sand dune were formed by the wind. When the wind blew over the sand dunes, it would carry some sand away and form a depression on the leeward side of the sand dunes. At the same time, the wind would also pile up sand on the windward side of the sand dune, forming a bulge. The effect of this wind caused the surface of the sand dune to form stripe-like uneven patterns. The shape and direction of these stripes depended on the strength and direction of the wind, as well as the shape of the dune. Therefore, the stripes on the surface of the sand dune were the result of the interaction between the sand dune and the wind.
How are sand dunes formed?
Sand dunes were landforms formed by the accumulation of sand driven by wind or water. The formation of sand dunes usually required dry and windy conditions. In a desert environment, high temperatures and lack of water would hinder the growth of vegetation and promote the formation of sand dunes. Sand dunes were not only found in deserts, but also in coastal areas, streams in semi-dry climates, glacial areas, and other areas with large amounts of loose sand. The sand dunes varied in shape and size and were divided into five types. The most common was the crescent-shaped dune, which had a longer upper side and a shorter sliding surface on the leeward side. During the formation of sand dunes, wind or water would pile up the sand grains, eventually forming the appearance of mounds, ridges, or hills. The sand dunes usually move at a speed of 30 meters per year. The existence of sand dunes could pose a threat to nearby farmland and residential areas. In short, the formation of sand dunes was the result of a combination of natural forces and environmental conditions.
How are moving sand dunes formed?
The moving sand dunes were formed by the wind. In the desert, the wind constantly eroded and transported the sand, causing a large amount of sand to pile up and move, forming countless moving sand dunes. The characteristics of moving sand dunes were that there was little vegetation on the surface, and their shape was typical. They were also easy to move along the wind. The movement speed of sand dunes is related to the height of sand dunes, wind speed and its variation rate, and the condition of the underlying surface. Mobile sand dunes are mainly distributed in China's Xinjiang, the Yellow Plateau, and the Inner Mongolia Plateau.

How were the Danniang sand dunes formed?
Danniang sand dunes were formed by the accumulation of wind power. Every winter and spring, the climate in this area was dry, 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. These air currents carried sand grains from the sandbars and floodplains, which were blocked by the mountainous terrain by the river. The wind speed slowed down, and the sand grains piled up on the hillside, forming Danniang sand dunes over time.
