Question

describing wind erosion and deposition
match each term about wind erosion and deposition with its description.
deflation
loess
abrasion
sand dune
sand deposited against an obstruction
the process by which wind moves particles that are loose
the process by which wind wears down solid objects
a deposit of fine, mineral-rich soil that is good for agriculture

Explanation:

1. Deflation is the wind-driven movement of loose surface particles.
2. Loess refers to fine, nutrient-rich wind-deposited soil ideal for farming.
3. Abrasion is the process where wind-borne particles erode solid objects.
4. A sand dune forms when sand accumulates against a barrier.

Answer:

• defalation → the process by which wind moves particles that are loose
• loess → a deposit of fine, mineral-rich soil that is good for agriculture
• abrasion → the process by which wind wears down solid objects
• sand dune → sand deposited against an obstruction
