Caption: Computer modelling of Earth's interior. This image shows the temperature distribution in surface rocks based on a model in which the core of the Earth is the source of internal heat, driving convection in the mantle. The colours show temperatures between 303 Kelvin (dark blue) and 1200 Kelvin (red). The small white arrows indicate the direction and speed of movement of the surface (maximum 9mm per year). Well-developed convection currents in the mantle have created volcanic 'hot spots' (red). This Earth was modelled by Dr John Baumgardner using a Cray Y-MP computer. Compare with E400/008.
