The ph scale is used to measure how acidic or basic a soil is. Soil formation occurs via a series of changes to the parent material, all of which lead to the formation of layers of soil, also called soil horizons. Systems of soil classification based on nature of parent The effects of these soil forming factors (weathering) results in the formation of layers within the soil from the surface down to varying depths depending on the intensity of the weathering. Most soils are given a name, which generally comes from the locale where the soil was first mapped. Encyclopedia of physical science and technology (third edition), 2003. Wetland soils tend to accumulate om since their saturation limits the rate of om breakdown. Denudation is the abrasion of present rock material by the action of ice, water or wind.
