Paleogeography is the scientific study and reconstruction of past geographic configurations of Earth’s surface, including the distribution of continents, oceans, mountain ranges, basins, and depositional environments through geologic time. It integrates data from plate tectonics, stratigraphy, paleomagnetism, sedimentology, paleontology, and geochronology to infer past positions and movements of tectonic plates and associated paleoenvironments. Paleogeographic reconstructions provide essential boundary conditions for paleoclimate modeling, basin analysis, sediment routing systems, and biogeographic studies, enabling quantitative assessment of how changes in Earth’s surface configuration have influenced climate systems, ocean circulation, biodiversity patterns, and the formation and distribution of natural resources.
You're an anaerobic microbe sunbathing on a Martian beach billions of years ago listening to the small waves hit the shoreline as you take in the perchlorates in the Martian regolith. This is because while Mars is warm and ...

About 600 million years ago, the continents wandered Earth, yet to settle into their current positions. Their locations during the Ediacaran (as this time is called) have been tough for scientists to pin down. Earth's magnetic ...
