When talking about soils, soils are typically divided into various horizons depending on what layers are present. The horizons include in this order: O Horizon <---- (Organic Horizon) - This is the top soil where plants grow. A Horizon B Horizon C Horizon Bedrock <---- This is lithified material. This means that there is no longer any lose soil at this point, and it has been turned to rock by pressure of overlaying sediment or other geological processes. Eluviation occurs in the E Horizon. The E Horizon is also known as the Zone of Leeching. By definition, eluviation is the process of removal of materials from geological or soil horizons. Essentially, this is where most of the weathering occurs in the soil. Illuviation occurs in the B Horizon. The B Horizon is also known as the Zone of Accumulation. By definition, illuviation is the deposition in an underlying soil layer of colloids, soluble salts, and mineral particles leached out of an overlaying soil layer. In layman's terms, this is where the particles end up in the B Horizon after they are weathered from the A Horizon.

Considering that these horizons are in order from top soil to unconsolidated bedrock, usually, a soil profile will have the Organic horizon, the A horizon, the B horizon, the C horizon, and the R horizon.
the horizon that contains topsoil is the A HORIZON
horizon B

THe c horizon
Soil layers are called soil horizons. Typically, a soil includes an A horizon, a B horizon and a C horizon. In laymen's terms: A horizon = topsoil B horizon = subsoil C horizon = parent material (the stuff in which the soil formed)
