Unformatted text preview: physical changes of materials within the soils profile from weathering processes. Translocation is the movement of materials, including salts, clays, and organic matter within the soil profile, usually from upper horizons to lower ones. The five soil forming factors ( parent material, climate, biota, topography, and time) affect the type, rate, and extent of the four processes, and ultimately control the kind of soil found in any one location. In the diagram to the right, the ‘O’ horizon represents an organic accumulation at the soil surface. The ‘A’ horizon is one exhibiting an accumulation of organic material and a darker color than the parent material. In the ‘B’ horizon, illuviated material has been deposited, From the photograph we can not tell what the illuviated material is, but it is likely clay from the upper horizons. The ‘C’ horizon represents unconsolidated material, which may or may not be parent material of the horizons above....
