Look it up. Jeez the nerve of some people

half of earths layer
Silicon is the element in the Earth's crust that has 14 protons. Quartz is crystallized Silicon Dioxide. Flint is also silicon dioxide. The compounds of Silicon are known as silicates.
Granite and basalt...... + a bunch of bugs n' stuff
Earths under crust surrounded by Upper Mantle (35-60 km) .The mantle is composed of sillicate rocks that are rich in iron and magnesium relative to the overlying crust.
Silicate minerals such as quartz and feldspar are the most common minerals located in earths crust
Earth's crust would be silica. Living things would be carbon.
Quartz and feldspars are the most common silicate minerals of the crust.
That element is Oxygen by 46.6%
The Earth's crust contains eight elements. The most common element among the eight is Oxygen (47 percent) and second is Silicon (28 percent).
The rarest element on earth is astatine and it is located in the earths crust. Astatine's availability is said to be less than a gram in weight.
The second most abundant element in the Earth's crust is silicon, comprising 27.8% of the crust by mass.
Aluminum :D
calcium is!
Feldspar is a common mineral that makes up over 60 percent of the Earth's crust. Feldspar was first found and worn as jewelry by people in Sri Lanka.
depends if you're talking about in the earths crust, in water or in the human boby. In us, carbon comes second. In the water, hydrogen. In the atmosphere ther is actually way more nitrogen than there is oxygen.
