How does the action og wind affect a rock appearance<br>​
Leona [35]
Wind causes the lifting and transport of lighter particles from a dry soil, leaving behind a surface of coarse grained sand and rocks. The removed particles will be transported to another region where they may form sand dunes on a beach or in a desert. Wind erosion is referred to as eolian erosion. Differences in atmospheric pressure will cause the motion of air that can erode surface material when velocities are high enough to move particles.
