Changes in Sea Level
Sea level is constantly changing, either because of differing amounts of water in the oceans or by variations
in the level of the land. These changes may give us more land, or take it away. The effects of erosion and deposition
and a change in sea level combine to modify the shape of the coast.
For example
- raised beaches provide areas of flat, coastal land in otherwise hilly areas
- estuaries and fjords provide sheltered, natural harbours.
