The vertical sequence of horizons in the soil which occur not as the result of stratification but as a result of weathering and other processes. The profile provides environmental or palaeoenvironmental information, such as information on vegetation and climate. The term also refers to a vertical section exposed in excavation or naturally that shows horizons and parent material. The soil profile is made up of some or all of the following: the A or humus horizon, the E or leached horizon, the B or (B) horizons or accumulation or chemical weathering, and the C horizon of parent material. Different soil profiles occur in different environmental regions, ranging from rendsinas, through brown earths, to podsols, gleys, and chernozems. The soil profile and the type of vegetation are interdependent, and man's activities have an effect on and are affected by both.
