Final answer:
Loose, mineral-rich soil deposited by wind erosion is called loess.
Step-by-step explanation:
When wind slows down and loses its energy, it deposits sediment it was carrying. The deposition of loosely packed, mineral-rich soil creates a feature called loess. Loess is made up of fine particles like silt, clay, and sand, and it is typically deposited in layers. It is commonly found in areas where wind erosion has occurred, such as arid and semi-arid regions.
