Summary
Episode 13: The surface of the Earth is divided into several tectonic plates of different sizes that slowly age and sink under one another. Scientists from universities of Lyon and Sydney took an interest in that phenomenon and have tried to understand why these plates are constantly in motion and why their sizes differ so much. By using animated 3D modeling of fictive planets, they have been able to study the development of tectonic plates and therefore learn more about the development of Earth itself.
