Suddenly, the pressure is too much and the plates jerk past each other. The place where this happens is called the focus. Vibrations go out in all directions through the r ...

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.
