Sand is a natural material made up of tiny particles, often found on beaches, deserts, and riverbanks. It is primarily composed of minerals like quartz, which gives it a gritty texture. Sand plays a crucial role in our environment, helping to create beautiful landscapes and providing habitats for various plants and animals. In addition to its natural beauty, sand is also important for human activities. It is used in construction to make concrete and glass, and it is essential for creating sandcastles at the beach. People enjoy playing in the sand, whether it's building structures or simply relaxing by the shore.
