Sea cliffs are created when the sea undercuts an area.
Through weathering and erosion, cliffs are sculpted. In contrast to hard rock, which is more resistant to erosion and creates high cliffs, soft rock erodes more quickly and produces gentle cliffs.
The most obvious signs of sea erosion that we can observe are coastal cliffs. The sheer rock and soil faces that make up sea cliffs are created by devastating waves.
A spit is a long, narrow ridge of sand that extends out from the coast; it partially blocks the opening of a bay and is made of sand.
