Final answer:
Loess is the feature created by the deposition of loosely packed, mineral-rich soil when wind slows down.
Step-by-step explanation:
The feature created by the deposition of loosely packed, mineral-rich soil when wind slows down is loess. Loess is a type of sediment that is composed of fine particles, such as silt and clay, that are easily transported by the wind and then deposited in a new location. It is typically found in areas with strong wind activity, such as deserts or near glaciers.
