Eolian refers to processes and features related to the wind. It describes how wind shapes landscapes, particularly in arid and coastal regions. Eolian processes include erosion, transportation, and deposition of sediments, which can create unique landforms such as dunes and loess deposits. Eolian features are commonly found in deserts and along shorelines, where strong winds can move sand and other particles. The study of eolian processes is important for understanding geology, climate change, and ecosystems, as these wind-driven changes can significantly impact the environment and human activities.
