What is sand? Composition & Types of Sand
Sand is a mixture of small grains of rock and granular materials which is mainly defined by size, being finer than gravel and coarser than silt. And ranging in size from 0.06 mm to 2 mm.Particles which are larger than 0.0078125 mm but smaller than 0.0625 mm are termed silt.. Sand is made by erosion or broken pebbles and weathering of rocks, which is …

The White Sands National Monument | Geology, Formation
Gypsum is a soft mineral with a hardness of 2 on the Mohs scale, which means that it can be easily crushed and broken down into small particles. This softness is what allows the sand to be easily blown and shaped by the wind. Additionally, gypsum has a unique ability to absorb and release water. This means that the gypsum sand at …
