3. Review physical and chemical properties. The skills for #1 are quite useful. The allow us to separate out the valuable components from raw materials. For example, it's good to know how to separate out gold flakes and nuggets from a gold and sand mixture. That depends on a knowledge of physical properties such as density and color.

SAND, SILT and CLAY Michigan State University

physical properties between clay and sand. The silt particles have limited ability to retain plant nutrients, or to release them to the soil solution for plant uptake. Silt tends to have a spherical shape, giving a high silt soil a soapy or slippery feeling when rubbed between the fingers when wet and is more difficult to form into a string ...
