Sand  Wikipedia
Sand is a granular material composed of finely divided rock and mineral particles. Sand has various compositions but is defined by its grain size. Sand grains are smaller 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 sandsized particles by mass. The composition of sand varies, depending on the local rock sources and conditions, but the most com
