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. [2]
Sand, mineral, rock, or soil particles that range in diameter from 0.02 to 2 mm (0.0008–0.08 inch). Most of the rock-forming minerals that occur on the Earth’s surface are found in sand, but only a limited number are common in this form.
At its core, sand is a granular material composed of finely divided rock and mineral particles. Technically, it’s defined by size, being coarser than silt and finer than gravel. The particles range in size from 0.0625 to 2 millimeters, according to the definition set by the United States Geological Survey.
