Sand is a naturally occurring granular material composed of finely divided rock and mineral particles. A close-up shot of sand from a beach in Vancouver.
The texture of groups or masses of minerals is said to be granular when distinct crystal faces are absent and the individual grains are about equal in length, breadth and height. Grains of salt and sand are examples of granular minerals. Granular texture is contrasted with crystalline texture.
