Answer to Question 1

Erosion on the ground surface resulting from the lifting and removal of individual particles by the wind is known as deflation. Where the wind encounters loose materials, deflation may remove enough material to form depressions in the landscape of different sizes. The smallest are known as deflation hollows (blowouts).

The grinding and shaping of rock surfaces by the sandblasting action of wind captured particles is known as abrasion. Rocks are pitted, fluted, and polished by this eolian process forming ventifacts. On a larger scale, deflation and abrasion are cable of streamlining multiple rock structures in a landscape, in alignment parallel to the most effective wind direction. The formations that result are called yardangs.
