Smaller particles moved by the wind occurs through deflation is "True".
Answer: Option A
Step-by-step explanation:
When the erosion occurs of surface materials or small particles which are loose in nature due to flow of high speed wind current in geological phenomenon than termed as "Deflation" .
These loose material belongs from plain areas of dry, uncemented sediments like which are present in dry lake beds, deserts, floodplains etc.
Deflation differs from wind abrasion because of the effect of particles borne by wind as the method of grinding away a solid object. Deflation reduces the surface of the soil which may produce a blowout which is a depression created by wind erosion on the surface of the land.
