British Scientists recently announced that the Earth's core, a bubbling mass of molten iron, burns along at 9,930 degrees Fahrenheit. That's pretty hot. However, scientists estimate the melting temperature of iron under such extreme pressure as found at the core of the earth is actually 11,730 F. The 1,800 degrees difference has been attributed to various impurities found in the core. But what impurities are at the Earth's core that could account for 1,800 degrees? We thought you'd never ask.
