Continental Drift
... Continents riding on the plates are 'twisted' (rotated) with respect to each other when the rate of sea floor formation differs near them, or even along their extension ‘parallel’ to the ridge. The most recent islands along the south Atlantic and Hawaiian arcs (and others around the world) are freq ...

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.
