The flameless burning element
Silicon in the Earth
I am a very important element. Did you know that you have silicon inside of you? I work with calcium to keep your skeleton strong and healthy. I also make up about 25.7% of the Earth's crust by weight. Together, me and oxygen make up 75% of the Earth's crust. silicon is the second most abundant element in the Earth's crust, right behind oxygen.
I exist in the Earth's mostly as silicon dioxide. I am found largely in silicon oxides such as sand, quartz, rock, crystal, amethyst, agate, flint, opal, and jasper.
