What is sand ?

Definition: Sand is a mix of small grains of rock and granular materials which is mainly define by size. As it finer than gravel and coarser than silt and the ranging in size from 0.06 mm to 2 mm. Particles which are larger than 0.0078125 mm but usually smaller than 0.0625 mm are termed silt.

Sand is made by erosion or broken of rock and weathering of rocks, which process is carried out  by seas or rivers also freezing and thawing during the winter. Most of the time Sand on beaches can also be made by small broken-up pieces of coral, bone, and shell, which are broken up by predators. Sand can be also considered as textural class of soil. Always sandy soil contain more than 85% sand-sized particles by mass.

Composition of Sand

Sand is basically made of unconsolidated granular materials consisting of either rock materials and mineral particles or else oceanic materials these are mainly made of silicate minerals and silicate rock granular particles. 

Quartz is the most available mineral as it highly resistant properties to weather. 

Feldspar is the most available found group of minerals on the earth surface and forms about 65% of the terrestrial rocks.
