The source of up to half of the Earth

WebAt the earth's distance from the sun of 147 million kilometers and a solar luminosity of 4 x 10^33 ergs/sec we get a flux of 1.8 Watts/cm^2. The interior of the earth contributes more than 99.5 percent of the total heating of the surface compared with the sun! This answer, of course is quite wrong because it assumes that 100% of the internal ... WebJul 27, 2024 · William Thompson, the first baron Kelvin worked out that the Earth was around 20 to 400 million years old, based on the rate of cooling from an assumed molten state. This would imply that the Earth's primordial heat would already be essentially lost, so you could argue the answer is zero (assuming Kelvin's calculation remains reasonable).
