Beaches are formed by deposition

1) Beaches are found on coasts between the high water mark ( the highest point on the land the sea level gets to) and the low water mark ( the lowest point on the land that the sea level gets to).

2) They're formed by constructive waves depositing material like sand and shingle.

3) Sand and shingle beaches have different characterisitics:

- Sand beaches are flat and wide- sand particles are small and the weak backwash can move them back down the beach, creating a long, gentle slope.

- Shingle beaches are steep and narrow- shingle particles are large and weak backwash can't move them back down the beach. The shingle particles build up and create a steep slope.
