What is Sand Made of?


Sand is a naturally occurring granular material composed of finely divided rock and mineral particles. It is formed through the erosion and weathering of rocks and minerals over millions of years. Sand is one of the most abundant resources on Earth and plays a crucial role in various industries and ecosystems.
