What is a beach, and what are the component parts of a beach? What will be an ideal response?

A beach is a deposit of unconsolidated sediment extending landward from low tide to a change in
topography, such as a line of sand dunes, a sea cliff, or the point where permanent vegetation begins.
A beach includes a backshore that is covered with water only during storms or especially high tides;
berms, platforms in the backshore composed of sediment deposited by waves; a beach face, the sloping
area below a berm exposed to wave swash; and the foreshore, an area covered by water during high
tide but exposed during low tide.
