We will see that the uppermost part of the lithosphere is cold so frictional sliding along faults governs the strength while at greater depth, the rocks can yield by non-lin ...

History of geology
The history of geology is concerned with the development of the natural science of geology. Geology is the scientific study of the origin, history, and structure of the Earth. Throughout the ages geology provides essential theories and data that shape how society conceptualizes the Earth.
