When light soils get moisture there occurs a cohesive force. At extreme low moisture the soil acts as a solid while at high levels the mix flow like a liquid. Atterberg, a Swedish scientist, created a way to define the consistency of such soils with changing moisture concentrations in the early 1900s. At extreme low moisture, the soil acts more like a solid when the moisture content is very low. The behavior of soil can be arbitrarily categorized into four fundamental states: solid, semisolid, plastic, and liquid depending on the moisture concentration. When the moisture content is sufficiently high, the soil and water may flow like a liquid. The shrinkage limit is determined by the percentage of moisture at which a solid becomes a semisolid. The plastic limit and liquid limit are the moisture contents at the transition points from semisolid to plastic and from plastic to liquid, respectively. “The Atterberg Limits" are all such parameters.
