Rheology, as you know, is the study of matter's flow, especially in liquid states. It is very useful in scientific fields, specifically geophysics and physiology.
determination of viscosity of medium.
The difference is in the rheology of the rocks, or, how they react under pressure. The lithosphere exhibits brittle rheology which means it will break or crack while the asthenosphere exhibits ductile rheology meaning it will deform or "flow in the solid state" not unlike silly putty. The lithosphere includes the crust and the upper part of the mantle and is approximately the upper 100km of the Earth.
Rheology in a geological context deals with the flow / deformation of the extremely viscous fluids that compose the asthenosphere and mantle (fluid in this context means that it flows but only on a geological time scale where strain rates are measured in metres / million years). In fact a better way may be to think of them as soft solids but that only act like they are soft way because of the very high temperatures and pressures they are under inside the earth.

It is useful because it is the root to most languages.

Yes, rheology is a real study. Rheology does have jobs available where people who are interested in rheology can practice rheology. The society of rheology has a website where all of the information is available.
Journal of Rheology was created in 1929.
rheology is the study of nature of rocks and the fluid found in the rocks with thier flow chracteristics
Rheology (the study of the flow of matter) has applications in engineering, biology, geophysics, pharmacology, and food production.
