Shore Buddies Wisdom Wednesday What is sand

Sand is made from large boulders being broken apart by wind or rocks. They get smaller and smaller until they reach the beach or a low lying area. It is defined by size, being finer than gravel and coarser than silt. The size of the sediment found on a beach is a good indication of the wave and wind energy in the area. Shorelines that are protected from waves and winds usually have finer sediment than exposed coastlines where small sediment is suspended within the turbulent waters.
