‘Geology’ comes from the Greek word Geo, meaning ‘the Earth’, and Logia, meaning ‘study’. Geology is therefore the discipline that studies the Earth, but there’s much more to it than that. In brief, geology is a scientific discipline that looks at the composition, structure and history of the Earth and other planets. And if that sounds like a mouthful, try being a geologist!
A geologist is a person who studies this discipline at university or college and is a specialist in any area of geology.
