S. Warren Carey in 1953, has the same Greek root as rheology, the science of viscoelasticity

shear waves, it may be deduced that it is a solid and, therefore, behaving as a rheid when it undergoes said convection. Granite has a measured viscosity at standard temperature and pressure of about 4.5×10¹⁹ Pa·s ^[1]

stress. Through this mechanism, salt domes and other structures may form. In some areas, such as the Gulf of Mexico, these structures often serve as traps for petroleum and natural gas
