Physical Properties of Soil. Soil Texture. The particles that make up soil are categorized into three groups by size – sand, silt, and clay. Sand particles are the largest and clay particles the smallest. Most soils are a combination of the three. The relative percentages of sand, silt, and clay are what give soil its texture.
Properties of Soils (Grades 3-5) Grade Level. 3 - 5. Purpose. Students discover that different soils have different characteristics, examine different types of soil, investigate soil components, and observe how air space allows soils to hold and transmit water. Grades 3-5. Estimated Time. Two 45-minute class periods plus short observations.
Properties of Soil. Soil is often described using several characteristics including texture, structure, density, temperature, color, consistency, and porosity. One of the most important properties of soil is the texture. Texture is a measure of whether the soil is more like sand, silt, or clay.

Soil formation is a process that requires concurrent action of Activities for Each Factor climate, organisms, relief, parent material and time, or CLORPT for short. CLORPT is responsible for the development of soil profiles and chemical properties that differentiate soils. Without CLORPT there will be no soil. Weathering takes place when ...
