Where does the heat come from that drives this convection current in the mantle The core and the mantle itselfWhere is the temperature of the mantle material greater at point A or point B Explain whyPoint A because its closer to the heat source the core 3.
Apr 07 2010nbsp018332Where does the heat come from that drives the convection in the mantle The heat comes from the outer core which provides the heat.
Dec 16 2020nbsp018332Earth generates heatThe deeper you go the higher the temperatureAt 25km down temperatures rise as high as 750176C at the core it is said to be 4000176CHumans have been making use of hot.
Initially the earth heated up using energy released by gravitational collapse and while this energy completely melted the planet this heat would have all been lost by now as the Earth is 4However the earth is still hot in its core as we can see from all the volcanic activity on our planet.
Jan 29 2020nbsp018332terawatts 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 crust and the primordial heat left over from the formation of the EarthEarths internal heat powers most geological processes and drives plate tectonics.
Jul 17 2011nbsp018332Berkeley Lab scientists join their KamLAND colleagues to measure the radioactive sources of Earth’s heat flowNews Release Paul Preuss 5104866249 • July 17 2011A main source of the 44 trillion watts of heat that flows from the interior of the Earth is the decay of radioactive isotopes in the mantle and crust.

Nov 27 2020nbsp0183321 AnswersThe heat comes from the sunfrom the core of the sun.
Q Q1 Answer the following questions 1 Rock dimension 10 m length and 5 m width subjected to stres.
Radioactive decay of uranium thorium and potassium in Earth’s crust and mantle is a principal source and in 2005 scientists in the KamLAND collaboration based in Japan first showed that there was a way to measure the contribution directlyThe trick was to catch what KamLAND dubbed geoneutrinos – more precisely geoantineutrinos – emitted when radioactive isotopes decayKamLAND stands for Kamioka Liquidscintillator Antineutrino Detector.
Sep 25 2017nbsp018332Why is the mantle and core so hot in the Earth The heat in Earths core come from a combination of factorsSome of it is heat leftover from Earths formation.
The Big Bang produced matter in the form of protons neutrons electrons and neutrinosIt took around 370000 years for the first atoms to form—protons attracted electrons producing hydrogenOther heavier nuclei like deuterium and helium formed at the same time in a process called Big Bang nucleosynthesis.
The creation of heavy elements was far more arduousFirst stars were born and heavy nuclei formed via accretion in their fiery crucibleThis process called stellar nucleosynthesis took billions of yearsThen when the stars died these elements spread out across space to be captured in the form of planets.
The energy which keeps the core hot and the volcanoes active is produced by radioactive decayHeavy radioactive elements such as uranium sank to the Earths core along with the Iron and Nickel early in Earths history when it was all molten and these radioactive elements have been heating the core rather like a nuclear power station ever since.
