A beach is a landform
along the shoreline of an ocean, sea, lake, or river. It usually consists of
loose particles, which are often composed of rock, such as sand, gravel, shingle,
pebbles, or cobblestones. The particles comprising the beach are occasionally
biological in origin, such as mollusc shells or coralline algae. The soothing
qualities of a beach and the pleasant environment offered to the beachgoer are
replicated in artificial beaches, such as "beach style" pools with
zero-depth entry and wave pools that recreate the natural waves pounding upon a
beach. In a zero-depth entry pool, the bottom surface slopes gradually from
above water down to depth. Another approach involves so-called urban beaches, a
form of public park becoming common in large cities. Urban beaches attempt to
mimic natural beaches with fountains that imitate surf and mask city noises,
and in some cases can be used as a play park. Source
