It takes hundred's even millions of years for sand to be formed from larger rocks that are broken down into smaller pieces by the wind and the flow of water tossing them around.Over years the erosion process,the particles are carried by wind and can form dunes,or are carried by water to river banks,lakes, or seas where they can form beaches. Sand that is found on the beach is mostly composed of quartz.
There are three grades of sand that can be found on beaches, fine,medium and coarse. Fine sand is 1/8 mm. to 1/4 mm. in diameter. Medium sand is 1/4 mm. to 1/2 mm. in diameter. Coarse sand is 1/2mm. to 1 mm. in diameter.
