Erosion by waves opened up a crack in the headland, which then became a cave and eventually an arch. The alternating bands of hard and soft rock run parallel to the coast. The Foreland, Old Harry and his Wife: The spit has continued to join to the Isle of Portland. The entrance to the cove is narrow where the waves have cut through weaknesses in the resistant limestone. Over time Old Harry will collapse to form a stump. This caused the formation of Old Harry, a stack.
This caused the formation of Old Harry, a stack. Dorsert is located on the southern coast of the UK. Towards the northern end of the bay the cliffs are covered in vegetation, stablising them and protecting them from erosion. Coastal management strategies are being used along the Dorset coastline to prevent erosion in some areas but they have impacted the landscape and caused changes to the natural environment. The soft rock is made of clay and sands, and the hard rock is chalk and limestone.
Behind the limestone is a layer of clay which is softer so more easily eroded.
The alternating bands of hard and soft rock run parallel to the coast. The limestone cliffs forming the back wall of the cove are vulnerable swanxge mass movement and sometimes experience small slides and slumps.
Coastlines where the geology alternates between bands of hard and soft rock which are perpendicular to the shore are called discordant coastlines. However, this creates a strong backwash which removes sediment from the beach and can lead to erosion under the wall.
Dorset is located in the south of England. How are geomorphic processes creating coastal landforms? As areas of the Dorset coast are being eroded, properities and infrastructure are at swanagee.
It connects the Isle of Portland to the mainland. They trap material being transported by longshore drift to create larger beaches which can then absorb wave energy to reduce erosion rates. The headland is made out of chalk, a hard rock.

The arch is gradually being worn away by mechanical, chemical and biological weathering. The spit has continued to join to the Isle of Portland.
Lulworth Cove is situated on the south coast of England, on a concordant coastline. Dorsert is located on the southern coast shudy the UK. How do climate and geolgy influence geomorphic processes?
This is made of chalk which is a harder rock. It is called the Jurassic Coast as it has lots of fossils dating back to the Jurassic period.
An ztudy at the end of the headland has collpased to form a stack called Old Harry and a stump called Old Harry’s Wife. The Foreland, Old Harry and his Wife: Sea wall Concrete sea walls are in place along most of Swanage beach.
This caused the formation of Old Harry, a stack. The areas where the soft rock has eroded away, next to the headland, are called bays. Groynes are wooden or stone barries which are built at right angles to the coast.
This swanae waves are slowed, reducing erosion and will help to protect proprties and cliffs.
Dorset – case study of a UK coastal landscape
The soft rock is made swabage clay and sands, and the hard rock is chalk and limestone. They reflect waves back sfudy to sea preventing erosion of the cliff. New timber groynes were installed on Swanage beach in and have reduced the loss of beach material. A concordant coastline has the same type of rock along its length.
Groynes Groynes are wooden or stone barries which are built at right angles to the coast. Longshore drift affects the bay carrying material mainly gravel from the south gegoraphy the north of the beach.
Erosion is the dominant process in the bay with the beach losing material year on year. Erosion by waves opened up a crack in the headland, which then became a cave and eventually an arch.
Over time Old Harry will collapse to form a stump. The headland juts out into the sea, so it is more vulnerable geoyraphy high-energy waves. In the wintersand and shingle were dredged from the sea bed at Poole Harbour and added to the upper parts of Swanage beach creating a wider beach.
