Question

How are sand grains transported by the wind?

Answer 1

Answer:

Option B, by saltation in the first few meters above the land surface

Explanation:

In the process of saltation, sand is carried by air and the sand grains remains suspended for a small distance till the fall down. These sand grains form a parabolic trajectory before falling down. The other characteristics such as height and time of suspended grains depends on grain size, shape, and density, lift  & drag force and characteristics of wind such as velocity and turbulence.  

Hence, option B is correct
