Concept:Wind action forms two groups of landforms: erosional and depositional.
The correct option must be a depositional landform created by wind.
Explanation:Loess is a wind-deposited landform made of fine silt and clay particles.
Strong desert winds pick up fine dust and carry it over long distances.
When the wind loses speed, it drops this dust, forming thick layers of loess.
These layers create fertile, yellowish soil over large areas.
Rock pedestal, Yardang, and Deflation hollow are all formed by wind erosion, not deposition.
A rock pedestal is an irregular pillar left after wind abrasion wears away softer rock.
A yardang is a long, sharp-edged ridge carved by wind in semi-arid regions.
A deflation hollow is a depression created when wind removes loose particles from the ground.
Only loess is actually deposited by wind.
Answer:D. Loess
