WebTopic 3. The Earth as a Heat Engine . The Earth is a body of stored heat, radiating into space. This heat is associated with two things; one is that the very high temperature of the inner parts of the Earth are very high, and the other is the result of heat generated due to radioactive decay of material in the deep Earth. WebMar 24, 2024 · This study indicates that iron alloyed with an upper bound of ∼2.2 (0.3) wt.% (∼10.7 [1.6] at.%) carbon may match with the Preliminary Reference Earth Model (PREM) in the Earth’s inner core. Thus, interstitial carbon in iron helps to explain the observed density deficit of the inner core, although other light elements are also expected.
