sand as a medium

Sand is a granular material composed of tiny mineral particles, typically quartz, that vary in size and shape. It acts as a versatile medium because of its permeability, allowing air and water to pass through easily. This makes it ideal for use in construction, filtration, and planting. In environments like deserts or beaches, sand’s loose structure shifts and responds to forces, providing stability or movement. Its inert nature means it doesn’t react easily with other substances. Overall, sand's physical properties—grain size, texture, and moisture retention—make it a practical and adaptable environmental medium.
