We Love Planet Earth

Did you know...if you could separate the Earth out into piles of material, you’d get 32.1% iron, 30.1% oxygen, 15.1% silicon, & 13.9% magnesium. Of course, most of this iron is actually located at the core of the Earth. If you could actually get down and sample the core, it would be 88% iron. And if you sampled the Earth’s crust, you’d find that 47% of it is oxygen.
