Document Summary
A study of the chemical, physical, biological properties of soils; soil formation and development; the classification of soils; the application of soil science to environmental issues; soil responses to environmental change. Dynamic natural bodies having properties from the combined effect of climate and biotic activities, as modified by topography, acting on parent material over periods of time. Dissolution (water hydration of minerals = dissociation [salt]) Oxidation-reduction (destabilizing of mineral due to oxidation) Landscape polydon pedon (soil profile) A vertical section of the soil through all of its horizons and extending into the parent material. A layer of soil, approximately parallel to the surface, differing in properties and characteristics from adjacent layers and above it. Topmost mineral horizon; partially decomposed matter gives soil a darker color; coarser texture. Undergone sufficient changes that original parent material is no longer discernable; materials. Including silicate clays, iron oxides, and aluminum oxides have accumulated. Loose enough to be dug with a shovel.
