This document summarizes soil formation, types, and composition. It defines soil and lists the main factors that affect soil formation: climate, original rock materials, organisms, topography, and time. Soil types are then described based on thickness (thick or shallow), development stage (young, mature, old), and particle size (sand, clay, silt, peat, chalk, loam). Each soil type is defined in terms of composition, properties like drainage and nutrients, and common locations. The stages of soil formation from rock weathering to a mature soil are also outlined.
