How did Earth\u2019s inner core freeze solid?<\/p>\n

Rost9\/Shutterstock<\/p>\n<\/div>\n<\/figcaption><\/figure>\n<\/p>\n

A high concentration of carbon within Earth\u2019s inner core could explain a long-standing mystery about how the deepest part of our planet froze solid \u2013 a process that kick-started the magnetic field protecting life on the surface.<\/p>\n

Earth\u2019s inner core presents a paradox for geophysicists: it first formed as a massive liquid ball of mostly iron<\/a>, then began to solidify within the last billion years. In order for that freezing process to start in a pure iron object, it would have had to cool by at least 700 kelvin in\u2026<\/p>\n<\/p><\/div>\n
