Sand is a naturally occurring granular material composed of finely divided rock and mineral particles. It is defined by size being finer than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e. a soil containing more than 85% sand-sized particles (by mass).

The composition of sand varies depending on the local rock sources and conditions but the most common constituent of sand in inland continental settings and non-tropical coastal settings is silica (silicon dioxide or SiO2) usually in the form of quartz. The second most common type 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 primary form of sand apparent in areas where reefs have dominated the ecosystem for millions of years like the Caribbean.
