The Earth's mantle is not static, he said, but moves by the process of convection: Hotter material from closer to the core rises and cooler material sinks in a cycle of vertical motion.

Earth's magnetic field and oxygen levels have increased more or less in parallel over the past 540 million years, suggesting the two factors are linked in some way, researchers say.
