Characteristics of a beach
What are the characteristics of sandy beaches?
A sandy shore is characterized by a sandy profile from the point where wave action reaches the sediment bed, through a wave-dominated subaqueous zone and a wind and wave dominated beach, up to the dune belt where aeolian processes dominate.
What type of environment is a beach?
A beach is a dynamic environment located where land, sea, and air meet. It may be defined as a zone of unconsolidated sediment (i.e., loose materials) deposited by water, wind, or glaciers along the coast, between the low tideline and the next important landward change in topography or composition.

What is the formation of a beach?
Beaches are made up from eroded material that has been transported from elsewhere and then deposited by the sea. For this to occur, waves must have limited energy, so beaches often form in sheltered areas like bays . Constructive waves build up beaches as they have a strong swash and a weak backwash .
What causes a beach to form?
Beaches are wave-deposited accumulations of sediment located at the shoreline. They require a base to reside on, usually the bedrock geology, waves to shape them, sediment to form them, and most are also affected by tides.
