Eolian processes refer to the actions of the wind in shaping the Earth's surface. These processes include the erosion, transportation, and deposition of sediments, primarily in arid and semi-arid regions. Wind can lift and carry small particles, such as sand and dust, over long distances, leading to the formation of features like dunes and loess deposits. Eolian erosion occurs when wind removes loose particles from the ground, while transportation involves the movement of these particles. When the wind loses energy, it deposits the sediments, creating new landforms. Understanding eolian processes is essential for studying landscapes in areas like deserts and coastal regions.
