Coastal features include sea stacks which are tall rock columns near the shore, rock platforms formed by wave action at the base of sea cliffs, and beaches deposited by waves. Other coastal features are bays surrounded by land, lagoons separated from the sea by barriers, tidal inlets connecting rivers and streams to the open ocean, sand dunes formed by wind, sea caves formed by wave erosion, rock arches with openings underneath, and blowholes which are vertical shafts connecting sea caves to the surface.

1. Coastal features

3. Sea Stack a steep and often vertical column or columns of rock in the sea near a coast.

4. Rock platform the narrow flat area often found at the base of a sea cliff or along the shoreline of a lake, bay, or sea that was created by the action of waves.

5. Beach occur along coastal areas where wave or current action deposits and reworks sediments.

6. Bay an area of water mostly surrounded by land.

7. Lagoon a body of shallow sea water or brackish water separated from the sea by some form of barrier.

8. Tidal inlet is a partly enclosed coastal body of water with one or more rivers or streams flowing into it, with a free connection to the open sea.

9. Sand dunes is a hill of sand built by aeolian processes (the winds ability to shape the Earth’s surface).

10. Sea cave a type of cave formed primarily by the wave action of the sea. The primary process involved is erosion.

11. Arch where a rock arch forms, with an opening underneath.

12. Blow hole is formed as sea caves grow landwards and upwards into vertical shafts and expose themselves towards the surface
