Article Description

This chapter discusses various energy sources. It introduces and discusses relevant physical and chemical properties of the earth's core studied from seismology, shock-wave data and core composition, and the thermal regime. The basic equations and conventional laws are set out and local equations, global energy balance, global entropy balance, and the magnetic field strength to the power supply are discussed. The possible power sources—radioactive heating, primordial heat and freezing of the inner core, gravitational energy release and adiabatic heating, chemical effects such as the heat of reaction between components, and precession and tidal forcing—are also explained. The chapter then summarizes the results from dynamo theory, freezing of the liquid in the outer core, and boundary layers, effects of stable density stratification. Finally, the thermal history of the Earth is outlined.
