4.3 - Soil Profiles and Horizons. Through the interactions of these four soil processes, the soil constituents are reorganized into visibly, chemically, and/or physically distinct layers, referred to as horizons. There are five soil horizons: O, A, E, B, and C. ( R is used to denote bedrock.) There is no set order for these horizons within a soil.

These layers are called soil horizons/layers and the arrangement of these horizons in soil or the vertical section of the soil is known as a soil profile.
