Iris: Thermal Convection: What Are the Forces That Drive Plate Tectonics?

Curated by ACT

Video introduces mantle convection which is the slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior of the Earth to the surface. It goes on to explain how the Earth's internal heat is the energy source for plate tectonics and gravity forces are what move the plates. [6:54]
