Relationships      
Parents Mixture A Mixture is two or more PureSubstances, combined in varying proportions - each retaining its own specific properties. The components of a Mixture can be separated by physical means, i.e. without the making and breaking of chemical bonds. Examples: Air, table salt thoroughly dissolved in water, milk, wood, and concrete.
Children ClayClay 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.
 LoamType of soil intermediate in texture between clay and sand, consisting of a mixture of clay, sand, gravel, silt, and organic matter.
 MudA Mixture of Soil and Water.
 SandSand 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.
 SiltSilt 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.
