Air currents will certainly transport small sedimentary grains. Dry clay particles are small enough to be held in suspension by the wind. Sand grains can be moved by a process known as saltation: bouncing grains along the ground or over other grains. It is by this process that sand dunes migrate. A storm will move tons of material in this way.
As sand grains are moved, they bounce and chip against each other and any exposed rock, breaking off small fragments and rounding the grains in their turn.

the wind picks up sand and tiny rocks and blows them around. when they are blown against a rock, they chip and scrape away at it. then, more tiny particals are formed, so more things are rubbing against the rock, so more is being scraped off. this very slow process is erosion. this also can work with water. but, the water also causes erosion without particles so it erodes things much faster.

Wind sweeps the upper layer of soil, which is fertile, once upper surface goes away, lower less fertile and less holding surface is exposed

b/c erosion means to blow or wear away and wind gradually wears away stone/dust/dirt stuff like that
