The factor which causes minimum influence to wind erosion at any particular location is:-

  • A.Climate
  • B.Fauna
  • C.Soil
  • D.Vegetation

Answer: B

The factor with minimum influence is Fauna.

Wind erosion at a place is governed mainly by climate (wind velocity, rainfall and soil moisture), by the soil itself (texture, structure, aggregate stability, surface roughness) and by vegetation, which shields the surface and slows the wind near the ground. These are the factors in the standard wind erosion equations.

Animals affect wind erosion only indirectly, for example when overgrazing removes plant cover; their own influence is small compared with the other three, which is why fauna is the answer.
