Magnetic field and heat flux: Effect of the subduction processes on the distribution of heat flow from the core into the mantle

Video: Calculated current distribution of heat flow at the core-mantle boundary (WMV)

The animation shows the calculated current distribution of heat flow at the core-mantle boundary. The heat flow beneath subduction zones of the last 300 million years exceeds the heat flux below areas where no subduction occurred many times over.
