Eolian processes refer to the various ways in which wind shapes and transports sediment in desert environments. This can include the formation of sand dunes, the erosion of rock surfaces, and the deposition of sediment in new locations. Eolian processes play a significant role in shaping landforms, altering ecosystems, and influencing climate patterns. Researchers in this field study how wind interacts with the landscape, the impact of eolian processes on local environments, and how these processes may change over time due to factors such as climate change.
