Soils are a resource, formed when parent material is weathered. Weathering is considered as a destructive one and helps to change the consolidated rocks and minerals into unconsolidated material (parent material) whereas second phase of soil formation is considered as a constructive process and develops the soil. Some scientists have been drawn to consider soil as a living tissue, with the soil solution acting like blood, transporting nutrients and waste products. Taxonomy (see soil classification section).
