Sand is critical to fracking.After workers drill down into rock, they create fractures by pumping in a mixture of water, chemicals and sand. The sand keeps the cracks propped open so that oil and gas are released. Frac sand mining creates significant air pollution from the handling, mining, and processing of the sand.
Sand naturally occurs as a granular material comprised of fine particles of rock and minerals. Silicon, a mineral compound that exists in silica sand, is actually silica dioxide. In technical terms rock and minerals become sand when reduced to a size from two millimetres to one sixteenth of a millimetre in diameter through weathering and other natural occurrences.
