The supercontinent Pangaea, with its connected South America and Africa, broke apart 200 million years ago. But the continents haven't stopped shifting -- the tectonic plates beneath our feet (in Earth's two top layers, the lithosphere and the asthenosphere) are still traveling at about the rate your fingernails grow. Michael Molina discusses the catalysts and consequences of continental drift.

Plate tectonics have alot to do with the world and how the world will evolve and in which way it will tranform in specific places. Pangaea involves not only Africa but also South America and how they broke away from the rest of the contenents about 200 million years ago. This idea involves the reality that the continents never stop shifting and the top two layer's of the Earth still grow at the rate of our finger nails grow. Divergent and Convergent boundries are apparent in the Earths ability to shift and eith come together or dive apart.
Very interesting that the earth has changed and continues to change. The continents have been separated over time and the example is there as Michael Molina explains that the continents of Africa and South America were once united as they have found remains of dinosaurs in eastern South America and West Africa.
