Windblown deposits of mineral-rich dust and silt is called loess. The term comes from the German word Loss and from the Alemannic word losch which means loose.
Over time, different sized particles within the parent material are redistributed and they separate into layers called horizons. These horizons can be seen in the soil profile, a vertical section of a soil visible when a pit is dug three to six feet deep. The topsoil, rich in organic matter, is called the A horizon. Leaching is the loss of materials from the A horizon when water carries clay and soluble matter downward.
