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.
