The Earth's crust is primarily composed of silicate minerals, such as feldspar and quartz, which contain silicon and oxygen as dominant elements. Carbon, while present in some minerals and organic matter, is not abundant in the crust compared to these silicate minerals. Additionally, the conditions during Earth's formation and subsequent geological processes favored the abundance of silicate materials over carbon-based compounds. As a result, carbon is found in much lower concentrations in the Earth's crust.

Is carbon fiber made from carbon?

Carbon fibre is generally greater than 95% carbon. Carbon fibre is made from a spun material that is very rich in carbon. It is usually a material called Polyacrylonitrile (PAN) or sometimes pitch, an oil derivative. These are heated in an inert atmosphere to drive off the other atoms, which leaves a fibre made almost entirely of carbon.
