Caption: Pangaea: break-up of a supercontinent. Frame from a computer model of Earth, showing the super- continent Pangaea 130 million years ago - 50 million years after it began to break up. A pattern has already emerged of existing oceanic plates being subducted under continental plates (dark blue margins) while fresh oceanic plates are being formed at constructive margins between continental plates (red/yellow areas). This model uses convection currents in Earth's mantle, beneath the crust, to power the break-up of Pangaea and the movements of the tectonic plates known today.
