Sand - Wikipedia

Sand is a 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 percent sand-sized particles by mass.

World Atlas of Sands » Sand

Sand can be defined as naturally occurring granular material having the grain diameter falling in the interval of 0.063 (1/16) to 2.0 mm. In the USA sand is usually classified by grain size into five main categories: very fine (1/16 – 1/8 mm), fine (1/8 – 1/4 mm), medium (1/4 – 1/2 mm), coarse (1/2 – 1 mm) and very coarse (1 – 2 mm).
