These animations illustrate several key elements of plate tectonics and show examples of how Earth's tectonic plates have moved over time. Watch Pangea split apart and form the modern continents, see mountains form in western North America and watch India collide with Asia. Animations created by Christopher R. Scotese, PALEOMAP Project/Northwestern University, and Ben A. van der Pluijm, University of Michigan. Read more about plate tectonics here: https://agupubs.onlinelibrary.wiley.com/doi/abs/
