Major portion of soil carried by wind is moved in the series of short bounce called?
Answer: A
The short bouncing movement is saltation.
Wind moves soil in three ways. In saltation, particles of about 0.1 to 0.5 mm are lifted, carried a short distance and dropped, bouncing along the surface; it carries the major part of the soil moved, often 50 to 75%. In suspension, very fine particles are carried high and far by turbulence. In surface creep, larger particles roll and slide along the ground, pushed by the impact of saltating grains.
So suspension and surface creep are real modes but carry less soil and do not involve short bounces.
