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.Sandstone is made of smaller, mostly sand-sized particles cemented together. Siltstone is made mostly of silt, particles that are smaller than sand but larger than clay. Shales have the smallest grain size, being made mostly of clay-sized particles and hardened mud. Typically, we classify these particles as either sand, silt, or clay based on their size. In the widely-used classification system of the United States Department of Agriculture, particles < 2.0 and ≥ 0.05 mm are considered sand, particles between < 0.05 mm and ≥ 0.002 mm are considered silt, and particles < 0.002 mm are considered clay. The broken particles are carried through water or air until they settle out in a lower area when the current wasn’t fast enough to carry the particles. Quartz is the most stable and has the greatest resistance to the mechanical and chemical abrasion during erosion, so most sand size grains are quartz. 20 Jun 2019 ...
