Exogenous Forces and Weathering
... The exogenous forces that act upon the earth are a combination of several complex natural events. One of these events of major importance is weathering. Weathering, in turn, involves two processes: fragmentation and decay. That is, rocks both break up and decompose. What causes these two processes o ...

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.
