Based temperature measurements show that the temperature of the earth's crust crust of 6,000 degrees celsius.Which means 1,000 degrees celsius hotter than expected. Temperatures of 6,000 degrees celsius is equivalent to the surface temperature of the sun.
The surprising results of measurements carried out by the research of scientists Sciences France (CNRS) and several other institutions are carried out on the inner and outer border of the earth by measuring the melting point of iron. The study was initially conducted to determine the formation process of the Earth's magnetic field. In order to form a strong magnetic field required temperature difference of 1500 degrees Celsius between the layers and the outer layer.
This study was repeated from previous studies can not be about providing a significant temperature difference.
Measurements of the melting point of iron in the study done by exploiting the properties of diffraction (spreading) X-ray When mashing the X-ray iron, then there will be a "sign" that the heated iron. From these measurements, as reported by LiveScience, Friday (26/04/2013), showed that the melting point of iron is 4,800 degrees Celsius, the pressure is 2.2 million times greater than the pressure above the Earth's sea level.
With the above formula predicted temperatures inside and outside the earth's layer of 6,000 degrees celsius.Results of the study published by the journal Science on Thursday (04/25/2013). This research will be used by seismologists to estimate the Earth's plates move.
