Earth 100 Million Years From Now - a very compelling short video - Earth's landmasses were not always what they are today. Continents formed as Earth's crustal plates shifted and collided over long periods of time. This video shows how today's continents are thought to have evolved over the last 600 million years, and where they'll end up in the next 100 million years. Paleogeographic Views of Earth's History provided by Ron Blakey, Professor of Geology, Northern Arizona University.
