The document discusses coastal landforms created by erosion and deposition. It describes erosional landforms such as wave-cut platforms, sea cliffs, sea caves, sea arches, stacks, and blowholes that are formed by destructive ocean waves. Depositional landforms include beaches created from rock debris, bars of deposited sand and debris along the coast, barriers that are above-water counterparts to bars, and spits and hooks which are projecting areas of deposition connected to headlands. Tombolos are described as islands connected by depositional bars.

Wave-cut Platforms
Sea Cliff
Sea Caves
Sea Arches
Stacks/ Chimney Rock
Blow Holes

4. Wave-cut Platforms: Destructive sea waves hit cliff face, undercut between the high and
low water marks, falls down, eroded over the time

5. Formation of Wave-cut Platforms

6. Sea Cliff: Vertical or nearly vertical, rock exposed along the sea coast

7. Sea Cliff

8. Sea Caves: Formed by mechanical sea wave and hydraulic erosion

9. Sea Caves

10. Sea Arches: Result of differential
erosion, varied rock resistance

11. Sea Arches

12. Stacks/ Chimney Rock: Column of rock rising above its surroundings

13. Stacks/ Chimney Rock

14. Blow Holes: Hydraulic compression of sea water released through top

15. Blow Holes

16. Coastal Depositional Landforms
Beach: Temporary covering of rock debris on or along a wave-cut platform
Bar: Tidal currents deposited rock debris and sand along the coast often submerged
at a distance from the shoreline
Barrier: Overwater counterpart of a bar
Spit and Hook: Projected deposition joined at one end to the headland. Hook:
Shorter spit with one end curved towards the land
Tombolos: Islands connected to each other by a bar
