... Explaining Compressional and Tensional tectonic Forces: Tectonic plates move or float on top of the asthenosphere. However they do not float freely. The plates are forced in specific directions by the flow of magma beneath. Just like a boat caught in a current plates move with the flow of magma. The ...

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.
