A
beach, or
strand, is a geological landform consisting of loose rock particles - such as sand, gravel, shingle, pebbles,
cobble - or even shell fragments, along the shoreline of a body of water. Beaches occur along coastal areas, where wave or current action

lake or

ocean, in all instances. A
seashore beach is merely one type of beach but it is the most commonly
associated with the perception of the word "beach".
