Eluviation.– Removal of dissolved or suspended material from a layer or layers of the soil by the movement of water when rainfall exceeds evaporation. Such loss of material in solution is often referred to as leaching. The process of eluviation influences soil composition.

Illuviation.– Accumulation of dissolved or suspended soil materials in one area or layer as a result of leaching (percolation) from another. Usually clay, iron, or humus wash out and form a line with a different consistency and color. These lines are important for studying the composition and ages of rock strata.
