4.Depositation: The material that has been eroded is transported by the waves to areas where deposition occurs: It happens when the sea piles up sand and pebbles to form new land
The movement of waves carries sand or shingle with them: swash carries onto a beach and the backwash carries it away
When a constructive wave carries sediment up the beach, the largest material is deposited along the upper reach of the swash
As backwash flows down the beach, it loses water and energy because the sand is porous. As a result, smaller and smaller sediments are deposited.
If a destructive waveform due to a storm, then a large shingle is thrown above the usual high tide level to form a ridge at the top of the beach called a berm
