The root of the word geology is derived from the Greek words geo, meaning ‘earth’, and logos, meaning ‘study’ or ‘discourse’. Thus, the root ‘geo-‘ refers to the earth itself, and when combined with ‘logos’, it essentially translates to ‘the study of the earth’.
This is fitting because geology encompasses the study of the composition, structure, and processes of the Earth. Understanding this root helps clarify the focus and scope of the subject, emphasizing its foundational connection to our planet.
