KnowraRadiogenic heatLinked fromLinked fromThe 7 pages that link to Radiogenic heat, each with the reason it gives.All 7Related 7Mantle convectionRelated: Internal heat generation that keeps the mantle convecting rather than cooling solid.Uranium-238Related: Uranium-238 decay contributes to Earth's internal heat over geological time.Potassium-40Related: Potassium-40 decay contributes to Earth’s internal heat budget.Thorium-232Related: Thorium-232 contributes to Earth’s internal heat through its decay chain.GeoneutrinoRelated: Geoneutrino flux constrains how much of Earth’s heat comes from radioactive sources.PoloniumRelated: Polonium’s decay releases energy, though its short-lived natural isotopes contribute little to Earth’s present heat.Natural hydrogenRelated: Radioactive decay supplies energy and radiation associated with some crustal hydrogen production.
