Get PriceABOUT SAND. Sand, along with gravel, silt and clay are collectively known as sediment, and are produced by the mechanical and chemical breakdown of rocks.Once disaggregated from the original source rock, this material is then eroded and transported by either wind, water or ice, often ending up at the deposits of rivers or lakes, as sand dunes, or ultimately as sediment in the sea.

Get PriceGrain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks. The term may also be applied to other granular materials. This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain.
Get PriceSand is the biggest soil particle. If blown up to an easily visible size, compared to other soil particles, a sand particle would be the size of a basketball. Soils classified as sandy typically contain 80 to 100 percent sand, zero to 10 percent silt and zero to 10 percent clay by volume.
Get PriceIn civil engineering, soil is a naturally occurring, loose/un-cemented/weakly cemented/relatively unconsolidated mineral particles, organic or inorganic in character, lying over the bed rock which is formed by weathering of rocks. Soil is formed by different particels such as gravel, rock, sand, silt, clay, loam and humus.
