About
A grain of sand is a tiny mineral particle measuring about 0.04 inches (1 mm) across.
By definition, sand grains are smaller than gravel but coarser than fine silt. In geology, particles classed as sand range from roughly 0.002 inches (0.06 mm) to 0.08 inches (2 mm) across. Most beach sand is made of broken-down quartz rock, which resists weathering long after softer minerals crumble away. Even at this tiny size, millions of individual grains pack together to create entire dunes and coastlines.
From Wikipedia
Sand is a granular material composed of finely divided mineral particles. Sand has various compositions but is usually defined by its grain size.
