The action of wind in a desert include the following except a
Glaciation
Abrasion
Attrition
Deflation
Correct answer is A
Glaciation is a term that has to do with ice Glacier itself is a large accumulation of frozen sea or river or ice.
Abrasion - here, small rock particles are hurles by wind against rock surfaces.
Attrition is a process by which rock particles rub against each other and wear away.
Deflation occurs when wind blows away rock wastes and in doing, lowers the desert surface thereby producing depressions.
Winds involve movement of particles when they blow, glaciation is often static and that makes it right answer.
