摘要: The melting gradient and the adiabatic throughout core of earth are compared. temperature iron at pressures equivalent to inner core-outer boundary is estimated be circa 4250°C with a point approximately 500° through outer core. 1250°; therefore, for liquid, its must considerably above in equilibrium inner-outer boundary. distribution deduced follow curve. This should provide substantial inhibition radial components convection
