Crushed Rock Storage Pile Wind Erosion

Causes Effects and Types of Erosion Water Wind Glacier

Wind causes erosion of rock particles driven by soil and sand particles that are not tightly glued together and not insulated by vegetation The carrying away of dry soil and loose sand particles is known as deflation The action of wind continues until that time when the power and momentum of wind cannot move the loose particles Glacier Erosion
