Chemical Composition of Sand?

Answer

Sand is occurs naturally in granular material made of finely alienated rock and in organic particles. The structure of sand is highly adjustable, depending on the local rock sources and conditions, but the most common component of sand in is silica (silicon dioxide, or SiO2), usually in the form of quartz The second most common form of sand is calcium carbonate, for example aragonite, which has mostly been created, over the past half billion years, by various forms of life, like coral and shellfish. It is, for example, the main type of sand apparent in places where reefs have dominated the ecosystem for millions of years like the Caribbean.
