Core surface temperature of about 3700 degrees Celsius.

<P Align=center> </ P> - Technology report [tech.] News: According to foreign media reports, experts from Massachusetts Institute of Technology recently successfully measured the surface temperature of the Earth's core. .According to their calculations, the core temperature of the surface of 6650 degrees Fahrenheit (about 3,700 degrees Celsius). .Scientists pointed out that the temperature just below the surface of the sun's temperature: the latter 9980 degrees Fahrenheit (about 5500 degrees Celsius). .<P Align=left> experts are on the mantle convection in the analysis of data reached these conclusions. .It is reported that the core to the mantle with the slow process of thermal convection and therefore continue to be heated. .</ P> <P align=left> involved in the research activities of the Robert Hill Crest, said they obtained from the Central American region, a detailed study of seismic data. .In addition, the experts also spread from the depths of the earth to the surface thousands of kilometers of seismic waves were monitored in real time. .</ P> <P align=left> scientists have pointed out that the transmission speed of seismic waves can tell us through the area on their chemical and physical properties. .By seismic data and comprehensive analysis of the rock composition data, the researchers ultimately determine the level of the Earth's internal temperature. .</ P> <P align=left> experts say, perovskite (a very rare mineral, is a variant of titanium) at a specific temperature and pressure will change under the so-called post-perovskite .mine shape. .In the Earth's interior, this change occurred in the area happens to be the junction of the mantle and core. .According to the experts calculated, leading to post-perovskite into perovskite is about 3700 degrees Celsius temperature. .</ P> <P align=left> the same time, according to the scientists estimated that the temperature inside the core should be higher, close to 5100 degrees Celsius. .</ P> <P align=left> MIT experts also calculated the Earth's core and mantle at the junction of the loss of heat energy per year - between about 7.5-15 trillion megawatts. .In comparison, the annual energy consumption of humanity is now about 13 trillion total megawatts. .</ P> <P align=left> at the core surface with the heat, about one third of the core product of radioactive radiation. .It is reported that the release of the core annual 42 trillion megawatts of energy. .</ P> </ p>.
