Sand is a natural material made up of tiny particles, often found on beaches, deserts, and riverbanks. It is primarily composed of silica, which comes from the weathering of rocks over time. The grains of sand can vary in size, color, and texture, making each location unique. People enjoy playing in the sand, building sandcastles, and relaxing by the water. In addition to its recreational uses, sand plays a crucial role in various industries. It is a key ingredient in making glass, concrete, and even silicon chips for electronics. The demand for sand has increased significantly, leading to concerns about its sustainable extraction and environmental impact.
