    Sand is usually defined as an accumulation of mineral grains in sizes ranging from one-sixteenth to two millimeters. Sand normally consists predominantly of quartz grains of variable degrees of roundness. Other mineral grains within the sand size range are also present and typically consist of feldspar, chert, ilmenite, and other less abundant resistant minerals. Gravel is considered to be an
