Mantle releases gravitational energy
WebThe total net (gravitational minus strain) energy released in the core by the process of inner core formation, 11.92×10 28 J, is not much less than the thermal energy released in this process, 15.1×10 28 J. In the mantle the net (gravitational minus strain) energy released by thermal contraction is about 20% of the heat release.

WebGravity peaks at the Gutenberg discontinuity (boundary between the mantle and outer core), which is about 2900 km underground or equivalently 3470 km as measured from Earth’s center. If you go upwards from this boundary, gravity would get weaker as you approach the surface of Earth, which is due to the non-uniformly distributed mass of the … WebMantle - 3488 km thick, made up of a ... and comes from a variety of sources.

WebSimultaneously, Earth’s core was accumulating and may have been completely formed during the planet’s growth period. In addition to the possible accretional heating caused by planetesimal impacts, the sinking of metal to form the core released enough gravitational energy to heat the entire planet by 1,000 K (1,800 °F; 1,000 °C) or more.
