Earth’s center is 1,000 degrees hotter than previously thought, synchrotron X-ray experiment shows

The temperature near Earth’s center is 6,000 degrees Celsius, 1,000 degrees more than given in an experiment 20 years ago. This experiment with synchrotron X-rays confirms geophysical models that explain Earth’s magnetic field and the creation and intense activity of hot-spot volcanoes. The scientists also established why the earlier experiment had produced lower temperature figures.
