Earth's crust would be silica. Living things would be carbon.
The sudden vibration in the plates inside the crust causes the earths crust to rise & fall.
In terms of weight, iron makes up approximately 5% of the earths crust, the fourth most abundant element in the crust. However, remember Earth's Core is nearly all Iron.
The earth's crust is not stress
continental crust
About 7% of the earths crust
The percentage of Earth's crust is less than one percentage in terms of Earth's volume. The Earth's crust is actually a thin layer.
its the percentage in mass !
Carbon makes up approximately 0.03% of Earth's atmosphere and is the fourth most abundant element by mass in the planet's crust.

Silicon is typically extracted from silica, which is found in the Earth's crust as quartz. The most common method to extract silicon involves heating silica with carbon in an electric arc furnace to produce silicon and carbon monoxide gas. This process is known as the carbothermic reduction of silica.
