weathering and erosion
The wind carrying sand grains deposits the sand when the wind's velocity decreases, or when an obstacle interrupts the wind flow. This causes the heavier sand grains to settle and accumulate, forming sand dunes.
formed in deserts from deposits of eroded Sand
A long winding ridge made from deposits of sand and gravel is called an esker. Eskers are formed by the melting of glaciers and the deposition of sediment as the flowing water carries and deposits material in a sinuous ridge-like form.
Wind erosion can lead to the formation of features such as sand dunes, loess deposits, and ventifacts. Sand dunes are mounds of sand formed by wind deposition, while loess deposits are composed of fine-grained particles carried by wind and then deposited. Ventifacts are rocks that have been sculpted and polished by wind-blown particles.
Sand dunes because, the wind blows sand and some sand hit large rocks, and they fall behind the large rocks, and the large rocks get covered in sand, but soon another large rock will do the same.

Wind causes deposition by carrying sediment particles, such as sand and dust, and depositing them when its speed decreases. When wind encounters obstacles or changes in landscape, it loses energy and drops the sediment it was carrying, leading to the formation of sand dunes, loess deposits, or other wind-formed landforms.
Sediment deposits, such as sand, silt, and clay, can build up land over time. These deposits are often carried by water, wind, or ice and accumulate in certain areas, gradually increasing the land mass. Additionally, volcanic deposits, such as lava and ash, can also contribute to the formation and growth of land.
Wind erosion and deposition may form sand dunes and loess deposits. When the wind strikes an obstacle, the result is usually a sand dune!
Aeolian deposits can be smooth sand sheets that can resemble a desert floor. They can be mobile sands that form active sand sheets or rugged vegetated sand sheets
The types of wind deposits include dunes, loess deposits, and sand sheets. Dunes are mounds of sand shaped by wind, while loess deposits consist of fine-grained sediment deposited by wind. Sand sheets are large areas covered with wind-blown sand.
Sand abrasion is the removal of sand from rocks. Rocks disintegrate into sand by natural forces.
