Sand is a naturally occurring granular material composed of finely divided rock and mineral particles. It is commonly found on beaches, riverbeds, and deserts. Sand is primarily made up of silica, which is a compound of silicon and oxygen, and it plays a crucial role in construction, manufacturing, and landscaping. Salt, or sodium chloride, is a mineral essential for human life. It is commonly used as a seasoning and preservative in food. Salt is obtained through the evaporation of seawater or mining of salt deposits. It is vital for various biological functions, including maintaining fluid balance and transmitting nerve impulses in the body.
