Geology is the study of rocks, gems, and minerals and the study of the structure of these materials. An important part is how they were formed and how they change over time.. UNIT 1. What is Geology. Geology is the study of Earth, including the materials that it is made of, the physical and chemical changes that take place on its surface and in its interior and the history of the planet and its life form.
