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.

砂（すな、英: sand）は、砕屑物のうち、礫とシルトの中間（粒径が2 ミリメートル (mm) - 1/16 mm (62.5マイクロメートル (µm)) の粒子）のものをいう。岩石が風化・侵食・運搬される過程で生じた岩片や鉱物片などの砕屑物（砕屑性堆積物）から構成され、サンゴ・貝殻などの石灰質の化石片を含むこともある。砂漠、河川の下流、河口、海岸、海底など、様々な下で観察される。また、岩石を人工的手段で破砕した破砕物のうち、上記定義に該当する粒度のものを指す場合もある。
