'Electric Earth' Could Explain Planet's Rotation

sciencehabit writes "When it comes to Earth's rotation, you might think geophysicists have pretty much everything figured out. Not quite. In order to explain some variations in the way our planet spins, Earth's mantle — the layer of hot, softened rock that lies between the crust and core — must conduct electricity, an ability that the mantle as we know it shouldn't have. Now, a new study (academic paper) finds that iron monoxide, which makes up 9% of the mantle, actually does conduct electricity just like a metal, but only at temperatures and pressures found far beneath the surface."

    FeO is Ferrous Oxide not Iron Monoxide.

    The topic at the moment is geology, not chemistry. Try to keep up.

    Bloody chemists. Grumble, mumble, ...

    FeO? That stuff is ugly.
