    The exact definition of sand varies. The scientific Unified Soil Classification System used in engineering and geology corresponds to US Standard Sieves, and defines sand as particles with a diameter of between 0.074 and 4.75 millimeters. By another definition, in terms of particle size as used by geologists, sand particles range in diameter from 0.0625 mm (or ​ ⁄16 mm) to 2 mm. An individual particle in this range size is termed a sand grain. Sand grains are between gravel(with particles ranging from 2 mm up to 64

    Formation of SandComposition of SandTexture and Transport of SandFurther ReadingSand forms mostly by the chemical and/or physical breakdown of rocks. This process is collectively known as weathering. Physical and chemical weathering are usually treated separately, but in reality they usually go hand in hand and it is often difficult to separate one from another because they tend to support each other. Chemical weathering is much more important sand-producing factor overall. It operates most efficiently in humid and See more on sandatlas.org
