Custom Soil Resource Report <br /> Episaturation <br /> A type of saturation indicating a perched water table in a soil in which saturated <br /> layers are underlain by one or more unsaturated layers within 2 meters of the <br /> surface. <br /> Erosion <br /> The wearing away of the land surface by water, wind, ice, or other geologic <br /> agents and by such processes as gravitational creep. <br /> Erosion (accelerated) <br /> Erosion much more rapid than geologic erosion, mainly as a result of human or <br /> animal activities or of a catastrophe in nature, such as a fire, that exposes the <br /> surface. <br /> Erosion (geologic) <br /> Erosion caused by geologic processes acting over long geologic periods and <br /> resulting in the wearing away of mountains and the building up of such <br /> landscape features as flood plains and coastal plains. Synonym: natural <br /> erosion. <br /> Erosion pavement <br /> A surficial lag concentration or layer of gravel and other rock fragments that <br /> remains on the soil surface after sheet or rill erosion or wind has removed the <br /> finer soil particles and that tends to protect the underlying soil from further <br /> erosion. <br /> Erosion surface <br /> A land surface shaped by the action of erosion, especially by running water. <br /> Escarpment <br /> A relatively continuous and steep slope or cliff breaking the general continuity of <br /> more gently sloping land surfaces and resulting from erosion or faulting. Most <br /> commonly applied to cliffs produced by differential erosion. Synonym: scarp. <br /> Escarpment, bedrock(map symbol) <br /> A relatively continuous and steep slope or cliff, produced by erosion or faulting, <br /> that breaks the general continuity of more gently sloping land surfaces. <br /> Exposed material is hard or soft bedrock. <br /> Escarpment, nonbedrock (map symbol) <br /> A relatively continuous and steep slope or cliff, generally produced by erosion <br /> but in some places produced by faulting, that breaks the continuity of more <br /> gently sloping land surfaces. Exposed earthy material is nonsoil or very shallow <br /> soil. <br /> Esker <br /> A long, narrow, sinuous, steep-sided ridge of stratified sand and gravel <br /> deposited as the bed of a stream flowing in an ice tunnel within or below the ice <br /> (subglacial) or between ice walls on top of the ice of a wasting glacier and left <br /> 43 <br />
