Because of The Aperture Science Portal Shooting Device... thingy. Deploying surprise in 5...4...3.... what what was that?
That was not the surprise...

Look it up. Jeez the nerve of some people
yes it is
half of earths layer
Granite and basalt...... + a bunch of bugs n' stuff
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.
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.
The most common minerals found in Earth's crust are quartz, feldspar, and mica. These minerals make up a significant portion of the Earth's continental crust and are essential components of many rock types.
Quartz and feldspars are the most common silicate minerals of the crust.
The most common element from group 13 in the Earth's crust is aluminum. It is the most abundant metal and constitutes about 8% of the Earth's solid surface. Aluminum is primarily found in minerals such as bauxite and feldspar, and it plays a crucial role in various industrial applications due to its lightweight and corrosion-resistant properties.
The main mineral that makes up the Earth's crust is called feldspar. Feldspar is a group of rock-forming minerals that make up about 60% of the Earth's crust by weight.
That element is Oxygen by 46.6%
The answer is 90%. The ten most common minerals make up 90% of the earths crust.
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.
silicate mineral group, which includes minerals such as quartz, feldspar, mica, and olivine. These minerals make up about 90% of the Earth's crust and are the building blocks of most rocks.
The most abundant metal in the earth crust is aluminium.
The second most abundant element in the Earth's crust is silicon, comprising 27.8% of the crust by mass.
Aluminum :D
