This can include sand, sediment and shingle. The beach is the area between the lowest spring tide level and the point reached by the storm waves in the highest tides.
Every beach is different but they are usually made up of material deposited on a wave-cut platform.
Longshore Drift Longshore drift is the movement of material along the shore by wave action. Longshore drift happens when waves moves towards the coast at an angle. The backwash carries material back down the beach at right angles. This is the reult of gravity. This process slowly moves material along the beach.
