A deposit of wind-blown sand is called a sand dune. Sand dunes form in deserts, beaches, and other areas where wind is able to transport and deposit sand grains.
I'm guessing you mean sand dunes.
Wind and water can move sand, with wind causing the grains to be transported in a process called saltation, and water moving sand through processes like erosion and sediment transport.
Wind removes sand and other sediment from the ground of deserts, beaches, and arid regions, where the force of wind can easily pick up and transport loose particles.
A mound or ridge of sand formed by the wind is called a sand dune. Sand dunes are common in deserts and coastal areas where there is a good supply of sand and strong winds that can transport and deposit it. The shape and size of sand dunes can vary depending on wind direction and speed.
Wind is commonly associated with moving sand-sized or smaller particles as an agent of erosion. The force of wind can pick up and transport particles like sand over long distances, leading to the process of abrasion and the formation of features like sand dunes.
Wind transports sand grains primarily through two processes: saltation and suspension. In saltation, sand grains are lifted off the ground and then fall back, bouncing along the surface, while in suspension, lighter particles are carried high into the air by the wind. This transport can lead to the formation of various landforms, such as dunes, as the wind deposits the sand in different locations. The effectiveness of wind in moving sand depends on factors like wind speed and grain size.
Landforms can be shaped by wind through processes such as erosion and deposition. Wind can erode rocks and soil, creating features like sand dunes, hoodoos, and rock arches. Wind can also transport sediment and deposit it in new locations, forming landforms like sand bars and deltas.
Deflation is the movement of dust, sand, and rock caused by wind erosion. Wind can pick up and transport loose particles, leading to the gradual removal of surface material in the process known as deflation.
The process that involves wind moving loose sediment is known as wind erosion. Wind erosion occurs when strong winds pick up and transport loose particles of soil or sand, which can lead to the formation of features such as sand dunes.
Wind carrying sand grains deposits the sand when the wind slows down or hits an obstacle.
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.
