Beach – The zone of deposited material that extends from the low tide line to the limit of the storm waves
The beached (beach) whale was lying between the limit of the storm waves and the low tide line.
Foreshore – High tide line to low tide line.
Backshore – High tide line to the extreme land limit of the beach.
A beach is a narrow strip of land between a body of water and an inland area. It slopes gently downwards from land to water and is covered in materials such as sand, pebbles and seashell fragments.
Beaches are formed from sediment in the water. The sediment is carried by incoming waves until they lose energy where they meet the shore. The sediment is then deposited, eventually resulting in a beach.
