Basic characteristics of soils. Size range of grains. Aids to size identification; The range of particle sizes encountered in soil is very large: from boulders with a controlling dimension of over 200mm down to clay particles less than 0.002mm (2mm). Some clays contain particles less than 1 mm in size which behave as colloids, i.e. do not settle in water due solely to gravity.
