A beach is a geological landform along the shoreline of a body of water. It usually consists of loose particles which are often composed of rock, such as sand, gravel, shingle, pebbles, or cobblestones. The particles of which the beach is composed can sometimes instead have biological origins, such as shell fragments or coralline algae fragments.
Beaches often occur along coastal areas where wave or current action deposits and reworks sediments.

A beach is a geological landform along the shoreline of a body of water. It usually consists of loose particles which are often composed of rock, such as sand, gravel, shingle, pebbles, or cobblestones.

The term 'beach' may refer to:
The former are described in detail below; the larger geological units are discussed elsewhere under bars.
There are several conspicuous parts to a beach, all of which relate to the processes that form and shape it. The part mostly above water (depending upon tide), and more or less...
