Earth's internal heat source
WebThe double-ellipsoid heat source, originally proposed by Goldak et al. (1984), has been used in many papers, e.g., Leung and Pick (1986), Das et al. (1993), and Michaleris (1997). The heat input is defined separately over two regions, see Figure 24. A comparison with measured temperatures is shown in Figure 25. WebNov 2, 2016 · Nov 2, 2016 at 20:00. 1. @GordonStanger -- Less than half of the internal heat escaping from the Earth is due to radioactive decay. The bulk of the remaining 50+% is due to primordial heat (secular cooling), the growth of the Earth's inner core, and gravitational energy from ongoing planetary differentiation. – David Hammen.
