Clay | Clay is fine-grained soil consisting of mineral particles, not necessarily clay minerals. Smaller than Silt (in the Wentworth Scale), clay particles range from 0.001 Millimeter to 0.004 Millimeter. | | | Loam | Type of soil intermediate in texture between clay and sand, consisting of a mixture of clay, sand, gravel, silt, and organic matter. | | | Mud | A Mixture of Soil and Water. | | | Sand | Sand is a Mixture of loose fragments of Minerals or Rocks. Smaller than pebbles and larger than Silt and Clay (in the Wentworth Scale), sand particles range from 0.062 Millimeter to 2 Millimeter in approximateDiameter. Sand is formed by %Erosion of rocks through the action of ater, Ice or Air. | | | Silt | Silt is sediment carried along by flowing water and deposited at a bend in a river or at a river's opening. Smaller than Sand and larger than Clay (on the Wentworth Scale), silt particles range from 0.004 Millimeters to 0.062 Millimeters. |
