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]
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.
Sand can be defined as the mixture of small fine grains of granular materials and rock. It is also commonly defined by size i.e. it is finer than gravel and coarser than silt ranging in size from 0.06mm to 2mm.

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.
Sand is more than just grains. Discover how sand forms, its mineral types, and what it reveals about Earth's surface processes.
