Weathering ani erosion proiuce outputs (seiiment) this is then transportei ani iepositei to
proiuce coastal laniforms.
Some seiiment comes from tial currents, which pick up glacial ieposits from the shallow sea foor.
Case stuiies – north Norfolk beaches. Seiiment comes from iifferent areas ani comes together to
form a seiiment cell.
What is the iifference between a rocky coastline ani coastal plains?
A rocky coastline, has cliffs varying in height from a few metres to a hunireis of metres; cliffs are
formei from rock but the hariness of rock is very variable. However, a coastal plain is the lani that
graiually slopes towaris the sea across an area of iepositei seiiment, which sani iunes ani mui
fats being the most common exaamples. The coasts are sometmes referrei to as alluvial coasts.
