The rock from which the soil is formed will have a direct affect on the type of soil, eg a sandstone will produce a sandy soil and a soil from limestone will have a higher pH (limestone being Alkaline) Soil texture. Typically soils are described on the basis of the presence of soil horizons and the character of the boundaries between horizons, the texture of the soil based on the size of the soil constituents, the color of the soil material, the structure of the soil, the presence of organic matter and roots, and the hydraulic conductivity. When we're done, the kids can clearly see that soil is made up of tiny, little rocks. If the soil is rough and grainy, there is a lot of sand in the soil. *A common method of measuring soil pH is performed by placing a glass electrode in a mixture of soil and deionized water.
