Episode 122 - Plate Tectonics

The Earth is in motion beneath our feet. The shifting and grinding of the tectonic plates is responsible for the shape of our planet’s surface and – directly or indirectly – nearly all the activity that happens upon it. Plate tectonics has a deep and fascinating history, both as a force that has shaped the Earth for billions of years and as a surprisingly recent foundational scientific theory.

In the news: shark teeth, Cambrian predators, Carnotaurus skin, and teratorns.
