Getting to Know: Plate Tectonics
... How are the rock cycle and tectonics related? The rock cycle involves the transformation of one type of rock into another. Plate tectonics are an important part of the rock cycle. Igneous rocks form from hardened magma that rises from the Earth’s mantle through gaps between the tectonic plates. Ove ...

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.
