Which parent material was formed by the forces of wind?

Explanation:
Wind can lift and carry fine particles like silt and then lay them down when air currents slow, building up thick, uniform layers known as loess. These wind-blown deposits become a soil’s parent material because they provide substantial, relatively homogeneous material that later soils can develop from. Loess is a classic example of a soil parent material formed by aeolian (wind-driven) processes. In contrast, alluvium comes from rivers, till from glacier ice, and sandstone is formed by cemented sand grains, not wind deposition. So the wind-formed parent material is loess deposits.
