what is sand? composition & types of sand - civil engineering. 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..

The chemical composition of sand is primarily SiO2, or silica. Silica, which is also named as quartz, is a type of mineral that makes up most of the sand types like beach sand. Quartz, which does not break easily, can be found in various types of rocks.

Much of the Earth's sand is identified as silica, or silicon dioxide, the two most abundant elements on earth. 95% of all rock is composed of silica, and when rock weathers, and then grind together in streams or rivers, bits are gradually worn away until the particles are tiny grains we call sand.

The sand that results in the formation of sand dunes is eroded from rocks by physical and chemical processes such as wind and water. The erosion leads to accumulation of sand. Strong winds pick up the sand and transport it (typically slightly above the ground) to another location. The strong wind transports sand in any of the 3 ways: Saltation
