Resumen de River of iron flows near Earth's core
Deep below the planet's surface, a molten jet pf iron, nearly as hot as the surface of the sun, is picking up speed. This stream of liquid some 420 kilometers wide has been discovered by telltale magnetic field readings 3000 kilometers below North America and Russia. It has trebled in speed since 2000, and is now circulating westwards at between 40 and 45 kilometers per year, heading from deep under Siberia towards the underside of Europe. That is three times as fast as the typical speeds of liquid in the outer core
