Thermal and Compositional Evolution of the Core

WebThe energy reaching the surface of the Earth from within can be measured to get heat flux, q.. q = - k dT/dz . Units of heat flux = Wm-2 which is equivalent to Js-1 m-2, and k is the thermal conductivity (Wm-1 K-1). The average heat flow from the Earth gives a q of approximately 0.08Wm-2 (equivalent to 80mWm-2).. But the flow is very uneven.
