AI overview

Sand is a granular material composed of small particles of rock and minerals, such as quartz, volcanic minerals, garnet, and olivine, as well as biogenic materials like coral. It is found in diverse environments around the world—from deserts like the Gobi and Idehan Ubari in Libya to locations in Estonia, Hawaii, and the mainland United States—and forms distinctive features like dunes that shape landscapes and ecosystems.

Sand is a granular material composed of finely divided mineral particles. Sand has various compositions but is usually defined by its grain size. 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.
