Rheology may be conveniently divided into bulk
rheology, in which effects due to the surface of the system can be neglected, and surface
rheology, in which such effects are predominant. It should be noted that in surface
rheology the neglect of bulk behaviour is permissible only in exceptional circumstances,
such as for very thin films surrounded by a gas.
