Plate tectonics: why only on Earth?
... difficult question is, how far plate tectonics reaches back in Earth´s 4.6 billion years of history. There is increasing geochemical evidence, however, that plate tectonics was established very early in Earth´s history, perhaps already within the first billion years. Therefore, it is rather surprisi ...

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.
