Earth's internal heat budget
Webthe total convective heat flux from Earth. If no more than 68% of Earth’s convective heat flux comes from radioactive decay, the planet’s thermal budget cannot be balanced, ruling out the possibility of a perfect thermal equilibrium suggested by Urey3. Also, Earth’s primordial heat supply could potentially Earth's internal heat budget is fundamental to the thermal history of the Earth. The flow of heat from Earth's interior to the surface is estimated at 47±2 terawatts (TW) and comes from two main sources in roughly equal amounts: the radiogenic heat produced by the radioactive decay of isotopes in the mantle and … See more Based on calculations of Earth's cooling rate, which assumed constant conductivity in the Earth's interior, in 1862 William Thomson, later Lord Kelvin, estimated the age of the Earth at 98 million years, which contrasts with the … See more Estimates of the total heat flow from Earth's interior to surface span a range of 43 to 49 terawatts (TW) (a terawatt is 10 watts). … See more Controversy over the exact nature of mantle convection makes the linked evolution of Earth's heat budget and the dynamics and … See more Media related to Earth's internal heat budget at Wikimedia Commons See more Radiogenic heat The radioactive decay of elements in the Earth's mantle and crust results in production of daughter isotopes and release of geoneutrinos and heat energy, or radiogenic heat.

WebEarth's internal heat budget is about heat that comes from the Earth itself, not heat from the Sun. The flow of heat from Earth's interior to the surface is estimated at 47±2 … WebEffectively, transfer of solar energy controls the temperature of the Earth's surface, internal heat controls the Earth's internal temperatures. About 80% of the Earth's present internal thermal energy is derived from radioactive decay of long-lived isotopes, primarily 232 Th, 238 U, 40 K, and 235 U (listed in order of decreasing importance).
WebThe heat budget of the atmosphere comprises 48 per cent of solar radiation wherein 14 per cent is received through absorption of the shortwave incoming solar radiation and 34 per cent is received from the outgoing long-wave terrestrial radiation.
