Earth's Crust: 200 per million by weight, 344 parts per million by moles.

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.
The crust is the layer of the Earth that contains granite and basalt in the greatest abundance. These rocks are commonly found in the continental crust (granite) and oceanic crust (basalt).
The earth's crust is not stress
blah
its the percentage in mass !
About 7% of the earths crust
Neodymium is relatively abundant in the Earth's crust, with an average concentration of about 38 parts per million. It is considered a relatively common rare-earth element compared to others in the lanthanide series.
Carbon
The abundance ratio by mass, in the earth's crust, is 1:2305, approx.
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.
The Earths crust is approximately 650 km deep.
Lithium is the 25th most abundant element in Earth's crust, with an average concentration of about 20 parts per million (ppm). This makes it relatively rare compared to other elements like silicon and oxygen.
Earth's crust would be silica. Living things would be carbon.
Protactinium is so scarce that the abundance in the Earth crust was not determined.
