Custom Soil Resource Report <br /> Sequum <br /> A sequence consisting of an illuvial horizon and the overlying eluvial horizon. <br /> (See Eluviation.) <br /> Series, soil <br /> A group of soils that have profiles that are almost alike, except for differences in <br /> texture of the surface layer. All the soils of a series have horizons that are <br /> similar in composition, thickness, and arrangement. <br /> Severely eroded spot(map symbol) <br /> An area where, on the average, 75 percent or more of the original surface layer <br /> has been lost because of accelerated erosion. Not used in map units in which <br /> "severely eroded," "very severely eroded," or"gullied" is part of the map unit <br /> name. <br /> Shale <br /> Sedimentary rock that formed by the hardening of a deposit of clay, silty clay, or <br /> silty clay loam and that has a tendency to split into thin layers. <br /> Sheet erosion <br /> The removal of a fairly uniform layer of soil material from the land surface by the <br /> action of rainfall and surface runoff. <br /> Short, steep slope (map symbol) <br /> A narrow area of soil having slopes that are at least two slope classes steeper <br /> than the slope class of the surrounding map unit. <br /> Shoulder <br /> The convex, erosional surface near the top of a hillslope. A shoulder is a <br /> transition from summit to backslope. <br /> Shrink-swell <br /> The shrinking of soil when dry and the swelling when wet. Shrinking and <br /> swelling can damage roads, dams, building foundations, and other structures. It <br /> can also damage plant roots. <br /> Shrub-coppice dune <br /> A small, streamlined dune that forms around brush and clump vegetation. <br /> Side slope (geomorphology) <br /> A geomorphic component of hills consisting of a laterally planar area of a <br /> hillside. The overland waterflow is predominantly parallel. Side slopes are <br /> dominantly colluvium and slope-wash sediments. <br /> Silica <br /> A combination of silicon and oxygen. The mineral form is called quartz. <br /> 64 <br />
