The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil. The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol. Each letter is described below (with the exception of Pt): If the soil has 5–12% by weight of fines passing a #200 sieve (5% < P#200 < 12%), both grain siz… WebbSoils are made up of different combinations of sand, silt and clay particles. Soils that are a mixture of sand, silt and clay are called loams. The name of the soil often identifies the dominant particle, for example, Timaru silt …

Soil texture is a permanent feature unless soils are subjected to rapid erosion, deposition, or removal. Moreover, much of the reactivity of soils is related to the amount of surface area available.
