What is the earth made of?

Well the earth is pretty much a hunk of iron
32.1 % iron, 30.1% oxygen, 15.1% silicon, and 13.9% magnesium the rest of the percentage is other materials
most of the iron is from the core of the earth. The core is made of 88% iron!!!

Yeahh! The iron gives the Earth it's magnetic field! Without it compasses wouldn't work!

So, there is more iron than oxygen in the Earth? What an interesting fact. Thanks for sharing.
