دردشة على الإنترنت Read More2020-4-4 Sand is composed of all kinds of rocks and minerals, so its chemical properties greatly vary. Most sand is made of quartz, which is largely silicon oxide. Physically, sand is made up of tiny, loose grains of rocks or minerals that are larger than silt but smaller than gravel. Quartz is a very hard mineral, ranking a 7 on the Mohs hardness scale.
