Sand is a combination of broken-down grains of rock and minerals that forms from physical or chemical weathering. It may also contain biogenic material, like snail shells, coral, seaweed, or more. Grains smaller than sand are silt and grains larger are gravel. The word sand comes from the Proto-Germanic word sandam.
