- Silicon comes from various sources and forms in nature12345:
- It commonly occurs as silicon dioxide (SiO2), also called silica, which cycles through the marine environment.
- It is formed through the oxygen-burning process in stars.
- It is found in rocks, sand, clays, soils, water, and even in certain plants and animals.
- It is one of the most common elements in the Earth's crust, typically found as silica sand.

It cycles through the marine environment, entering primarily through riverine runoff. Silica is removed from the ocean by organisms such as diatoms and radiolarians that use an amorphous form of silica in their cell walls.www.britannica.com/science/siliconSilicon is formed through the oxygen-burning process in stars. Silicon reacts with oxygen to make silicon dioxide or silicates. Silicate minerals make up over 90% of earth’s crust. Silicon is rarely found in pure form. Group of minerals composed of silicon and oxygen are named silica. Silica is mostly found in crystalline state.periodic-table.com/silicon/It is found in rocks, sand, clays and soils, combined with either oxygen as silicon dioxide, or with oxygen and other elements as silicates. Silicon's compounds are also found in water, in the atmosphere, in many plants, and even in certain animals.www.madehow.com/Volume-6/Silicon.htmlWhere Does Silicon Come From? Silicon is one of the most common elements found in the earth’s crust, second only to oxygen. It’s often mined in open pits or via dredging, but the environmental impact of this process is minimal. This element can present in a couple different forms, but typically it’s silica sand.www.waferworld.com/post/the-silicon-supply-chainSecond only to oxygen in abundance in Earth’s crust, it never occurs free but is found in almost all rocks and in sand, clay, and soils, combined with oxygen as silica (silicon dioxide, SiO 2) or with oxygen and metals as silicate minerals. It occurs in many plants and some animals.www.britannica.com/summary/silicon - People also ask
