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 sand-sized particles by mass.. The composition of sand varies, depending on the

The particles in finer-grained detrital sediments are usually composed of quartz. They fall into two size grades: sand (2 mm-62 μm) and silt (62 μm-2 μm). These size gradings conceal important geological processes since there are geological controls on both the quartz sand and silt populations. Sand nature is largely controlled by geochemical reactions, for example in cooling granite from

Sand is a very generic term. It means a mineral substance that has particles smaller than gravel but larger than silt or clay. Sand is defined by the size of the particles, the shape of the particles, and the minerals used to make up the particles. As footing, sand is also defined by how deep the sand is.

The processes that produce fine mineral aerosols are distinct from those that produce quartz-rich silt and are dominated by the impact of saltating sand particles on fine-grained soils and sediments (Kok et al., Reference Kok, Eric, Timothy and Diana Bou 2012 and references therein).

Clay or silt breaks down into individual particles of its minerals: feldspar, quartz, and mica.
