Soil is a heterogeneous mixture of inorganic minerals, organic materials and biological matter the consistency of which varies horizontally and vertically along the surface of earth. This inconsistency arises because the factors which influence the formation of soil - temperature, rainfall, humidity, atmospheric pressure and composition of parent rocks - differ from place to place. It is therefore pertinent that the soil of one location is different from that of another location not only in its chemical constituents like ions, polymers and carbonaceous deposits, but also in
physical parameters like color, texture and density. Such diverse characteristics serve as identification markers for different units of landscape and make soil a valuable evidence to link a suspect to the crime scene.
