Sand is a form of granular sediment composed of mineral fragments, most commonly quartz ($\text{SiO}_2$), defined by particle sizes typically ranging from 0.0625 to 2 millimeters. The physical properties of sand are dictated by its mineral composition, particle angularity, and sorting degree, which determines its hydraulic and mechanical characteristics. In scientific and industrial applications, it serves multiple functions, including acting as a filtration medium in water treatment and purification systems, where its porous structure removes contaminants. Furthermore, due to its abrasive nature, processed sand is integral to many mechanical processes, and its silica content makes it a primary raw material for glass manufacturing and specialized construction materials.
