Sand is a large accumulation of small rock and/or mineral particles in the size range of from 20 micrometers to 2,000 micrometers in diameter. Sand may include small shells or shell fragments and oolitic deposits. Sand is a size and density segregated material that is the result of air or water action.

The sand here was washed with dilute hydrochloric acid to remove gypsum, carbonates
and shell fragments.
