Sand McGill University

Sand is a granular material made up of fine rock particles. Sand is a naturally occurring, finely divided rock, comprising particles or granules ranging in size from 0.0625 (or 1 16) to 2 millimeters. An individual particle in this range size is termed a sand grain.The next smaller size class in geology is silt particles below 0.0625 mm down to 0.004 mm in size.
