Geology (from Greek γη- (ge-, "the earth") and λογος ("logos", "word", "reason")) is the science and study of the solid matter of a celestial body, its composition, structure, physical properties, history and the processes that shape it. In this book, the term Geology will apply to the Earth in particular.

Geology can be split into two main branches: historical and physical. Historical geology attempts to understand the origins, composition, systems and changes of the Earth.
