Coastal Erosion

Headlands A Headland is a narrow strip of land that projects out into a body of water. It possess cracks and gaps that water can lodge into causing Hydraulic Erosion. This is an image of the Barwon Heads headland called The Bluff.

Wave-Cut Cliff  A Wave-Cut Cliff is a steep rock face created by the eroding action of waves.  This is loated on the Great Ocean Road (the 12 apostles).

Wave-cut Platforms  A flat area found at the base of a wave-cut cliff. This is formed from wave- cut cliffs crumbling and being washed away and leaving behind these small platforms.  This is located in Southerndown, Wales.

Sea Cave  A sea Cave is a cave formed from the constant crashing of waves onto the cliff face. The hydraulic erosion (in cracks in the rock face) causes the rock where the waves crash to crumble and disappear, leaving a cave.  This is located in Dwejra Bay, Victoria

Sea Arch  A Sea Arch is a natural hole carved through a headland, due to erosion by waves. Wave refraction and erosion from waves causes this arch. This is located on the Great Ocean Road.

Sea Stack  A Sea Stack is a column of rock standing in the sea detached from a cliff. This occurs from refractive waves destroying the headland and leaving a sea arch that eventually crumbles due to gravity.  This is a picture of the 12 apostles on the Great Ocean Road.

Sea Stump  A sea stump is a small column of rock that barely comes above the surface of the ocean. It is cause by the sea stack being eroded by waves until it falls and only a stump is left.

Tombolo  A tombolo is derived from the Latin tumulus which means ‘mound’, is a landform in which an island is attached to the mainland by a narrow piece of land created by longshore drift.  This is a picture of a tombolo in Japan called the Angel Road.
