A dust devil is a phenomenon caused by rapid air circulation at the surface of the Earth, typically occurring in arid or semi-arid regions. Dust devils do not directly cause erosion, deposition, or weathering, but they can transport loose particles, such as dust or sand, over short distances.
Loess is a result of deposition. It is a clastic, predominantly silt-sized sediment that is formed by the accumulation of wind-blown dust.
There are several other names for a dust devil including desert devil, sand devil, dust swirl and dancing dervish. Despite appearances, they are not tornadoes.
Running water: Rivers and streams can erode rocks and soil as they flow, carrying sediment downstream and depositing it in new locations. Wind: Strong winds can pick up and transport small particles like sand and dust, causing erosion in one area and deposition in another. Glaciers: As glaciers move, they can carve out valleys through the process of erosion and deposit sediment as they retreat, forming moraines and other landforms.
Whenever soil is exposed, water and wind can quickly erode it. Plant cover can protect soil from erosion. Plants break the force of falling rain, and plant roots hold the soil together. Wind is another cause of soil loss. Wind erosion is most likely in areas where farming methods are not suited to dry conditions. For example, wind erosion contributed to the Dust Bowl on the Great Plains.
No, a dust devil is not a tornado. A dust devil is a small, rotating column of air that forms on hot, sunny days when the ground is dry. Tornadoes, on the other hand, are violent, rotating columns of air that form in severe thunderstorms. Dust devils are typically harmless, while tornadoes can be destructive and life-threatening.

Because the moon has neither liquid water or an atmosphere on its surface, there is very little weathering or erosion. Any weathering or erosion that does place is caused by repeated meteorite impacts, which break up and scatter the rocks and dust on the Moon's surface.
Sedimentary rocks are formed by the weathering, erosion and then deposition of the resultant clasts. Weathering and erosion do not occur on the moon (except to a limited extent due to the impact of meteorites but this material is not compacted so is a dust rather than a rock) so sedimentary rocks can't form.
Physical weathering is the breakdown of rocks into smaller pieces without changing their chemical composition. It is caused by factors such as temperature changes, abrasion from wind or water, and ice formation in cracks.

A dust devil is the color of the dust it is going over, which varies. They are often a light tan to rusty red color.

Well, darling, Uluru is mainly affected by physical weathering due to extreme temperature changes causing the rock to expand and contract. Erosion also plays a role, with water and wind slowly breaking down the sandstone layers over time. So, in a nutshell, both weathering and erosion are giving Uluru a bit of a makeover, whether it likes it or not.

Erosion is the process of rock or soil being washed away by wind or water. In this process the particles are carried from the parent rock and when the force of wind or water drops , the particles of sand or dust drop to the surface leaving deposition. Wind erosion is called aeolian erosion. As the particles are blown or washed along, they bounce in steady patterns along the ground, so when the wind drops they are deposited in patterns, hence the patterns of ripples on desert sand and at the bottom of the sea, this bouncing is called saltation.
A dust devil is a small long-lived whirlwind which is visible as a column of dust. The Navajo called them as chiindii, ghosts or the spirits of dead Navajos.
