1) Define soil color, texture, acidity and alkalinity, and structure. - Soil color varies from region to region. In some areas, soil color is inherited from the mineral parent material, but usually it is generated during soil formation. - Soil texture refers to the proportion of particles that fall into each of 3 size grades- sand, silt, and clay. - Soils in cold, humid climates typically have high acidities, while in arid climates, soils are typically alkaline. - Soil structure refers to the way in which soil grains are clumped together into larger masses, called peds. The particles are bound together by soil colloids to create peds ranging from small grains to large blocks. 2) Describe the soil-forming processes: enrichment, removal, and translocation (including eluviation, illuviation, decalcification, calcification, and salinization), and organic transformations. - During soil enrichment, matter, organic or inorganic material is added to the soil. In the removal process, material is either eroded away from the soil, or leached from the soil by seeping water and taken to the ground water. Translocation describes the movement of materials upward or downward within the soil. Eluvuation describes the downward movement of material. Illuvation is the
