As evidenced in his treatise Meteorology, Aristotle also dabbled in the earth sciences. By meteorology, Aristotle didn’t simply mean the study of weather. His more expansive definition of meteorology included “all the affectations we may call common to air and water, and the kinds and parts of the earth and the affectation of its parts.” In Meteorology, Aristotle identified the water cycle and discussed topics ranging from natural disasters to astrological events. Although many of his views on the Earth were controversial at the time, they were readopted and popularized during the late Middle Ages.
