Alex Copley on Soft Continents
Manage episode 429004205 series 3293313
We tend to think of continental tectonic plates as rigid caps that float on the asthenospheric mantle, much like oceanic plates. But while some continental regions have the most rigid rocks on the planet, wide swathes of the continents are not rigid at all. In the podcast, Alex Copley explains how this differentiation comes about and points to evidence that the responsible processes have been operating since the Archean.
Copley is Professor of Tectonics in the Department of Earth Sciences at the University of Cambridge.
