The Earth's crust is formed mainly from the elements aluminum, silicon and oxygen in the form of silicates & aluminum oxides and occurring as silicate rocks.
Silicate minerals are abundant in all three rock types (igneous, metamorphic, and sedimentary) comprising the crust, but the crust is composed mainly of silicate rich igneous rock. The continental crust is composed of the lighter 'felsic' igneous rock (granitic in nature), higher in aluminum, sodium, and potassium; the oceanic crust is composed of the heavier, darker, 'mafic' igneous rock (largely basalt) which is higher in iron and magnesium than the continental crust.
Crust composition: Oxygen, Silicon, Aluminum, Iron, in that order.
Overall composition of the entire Earth: Iron, Oxygen, Silicon, Aluminum, in that order.

Why is earths composition of earths atmosphere important?
The Chemical Composition of the Earth's atmosphere is important because it holds the Earth together.
How does amethysts form?
Silicon dioxide (SiO2) is the chemical composition of amethyst. It is a mineral which is formed like anyother mineral under the earths crust due to heat and pressure.

How do the elements in the human body compare to elements in the earths crust?
the chemical composition of human beings are similar to that found in the reminisce of stars after they impload this answer is correct human beings cant be chemically composed like earths crust because we arent formed from silicates and crystals
