Basically, the engineering definition of the world "soil" is very broad one. Soil might be defined as all the earth material, both organic and inorganic, that blankets the rock crust of the earth. Practically all soils re products of the disintegration of the rocks of the earth's crust. This disintegration, or "weathering," has been brought about by the action of chemical and mechanical forces that have been exerted on the parent rock formations for countless ages. Included among these forces are those of wind, running water, freezing and thawing, chemical decomposition, glacial action, and many others.
Soil may be described in terms of the principal agencies responsible for their formation and position. Thus a "residual soil"; is one that, in its present situation, lies directly above the parent material from which it was derived. Soils formed by the action of wind are we known as "aeolian soils"; a typical example of a windblown soil deposit is seen in the very considerable deposits of losses in the Missisipi Valey."Glacial soils" occur in many parts of the United States. An example of such a soil deposit is a glacial till, which is a deposit of tightly bonded materials containing particles ranging in size from boulders down to very finely divided mineral matter
