WebThe C horizon is a layer of poorly weathered or unweathered rock. It contains a high concentration of parent material and is generally infertile. Soil erosion is the removal of the fertile top layers of soil. Soils can be eroded naturally by wind and flowing water. Erosion can be slowed by plants, whose roots help anchor the top layers of soil.

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.
