Earth's continents are still moving at the speed of your growing fingernails.

The Pangaea Pop-up - Michael Molina · 4:26 · Video: TED-Ed · Watch at the source

In short: Michael Molina explains the mechanics of continental drift, detailing how the supercontinent Pangaea fractured 200 million years ago. This video explores the ongoing movement of tectonic plates within Earth's lithosphere and asthenosphere, revealing the forces that continue to reshape our planet today.

Around 200 million years ago, the supercontinent Pangaea began to break apart, separating landmasses like South America and Africa. This process is driven by the movement of tectonic plates located within Earth's two outermost layers: the lithosphere and the underlying asthenosphere.

These plates remain in constant motion, drifting at a pace comparable to the growth rate of human fingernails. Molina examines the catalysts behind this persistent shifting and the significant consequences it has for the structure of our world.
