The shaping of the Earth's surface by wind is referred to as eolian processes. This term encompasses various methods through which wind erodes, transports, and deposits sediment. Wind can pick up loose particles and carry them across vast distances, contributing to the formation of features such as dunes and eroding landforms. The effectiveness of these processes is influenced by factors such as wind speed, sediment availability, and vegetation, which can protect the soil from erosion.

Mechanical weathering refers to the physical breakdown of rocks without altering their chemical composition, while mass wasting involves the movement of soil and rock down slopes due to gravity. Hydraulic action pertains to the erosion caused by the movement of water, typically in rivers and oceans, rather than wind. Thus, eolian processes specifically identify wind's role in sculpting the landscape.
