Earth's crust would be silica. Living things would be carbon.
Silicon
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.
Aluminum is the Earths most abundant metal and its located in the Earths outer crust.One of the properties of crust is that it consists of a variety of sedimentary,metamorphic and igneous rocks.
That element is Oxygen by 46.6%
The second most abundant element in the Earth's crust is silicon, comprising 27.8% of the crust by mass.
Aluminum :D
calcium is!
Silicon
That would be silicon, or SiO2
