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. Beaches
typically occur in areas along the coast where wave or current action deposits
and reworks sediments. Source
