A beach is the land along the edge of a body of water, usually made of sand, gravel, pebbles, or cobbles. It can be hundreds of kilometers long or a few hundred feet wide.
The shape of a beach depends on the wave action and on the size of the sand grains. Larger sand grains tend to be moved back by waves while smaller sand grains stay on the beach until they are buried in the sand during erosion. This process creates an area called a beach berm, which is usually the upper part of a beach.
At the bottom of a beach there may be a trough and at seaward, one or more long shore bars: slightly raised embankments formed by the waves as they break.
