Paleogeography is the study of the physical geography of the Earth in the past. This field of research focuses on reconstructing the positions and movements of continents, oceans, and other landforms throughout geological time. By studying paleogeography, researchers can better understand ancient environments, climate patterns, and the evolution of life on Earth. This interdisciplinary field combines principles from geology, paleontology, and geography to create detailed maps and models of Earth's past geography.
