Because there’s no erosion, there is no material to replenish the beach meaning the beach level will become lower. Dorsert is located on the southern coast of the UK. Then the cove widens where the softer clays have been more easily eroded. Dorset is located in the south of England. The headland is made out of chalk, a hard rock. Elsewhere, the cliffs are not covered by vegetation, so wet weather weakens them causing slumps.
This means waves are slowed, reducing erosion and will help to protect proprties and cliffs. The Foreland, Old Harry and his Wife: How is human activity, including mangement, working in combination with geomorphic processes to shape the landscape? It is called the Jurassic Coast as it has lots of fossils dating back to the Jurassic period. This is made of chalk which is a harder rock.
There is also a risk for people from landslides and swanae. This means waves are slowed, reducing erosion and will help to protect proprties and cliffs. Behind the spit there is The Fleet, a lagoon. Over swanafe Old Harry will collapse to form a stump. They reflect waves back out to sea preventing erosion of the cliff. This caused the formation of Old Harry, a stack. It connects the Isle of Portland to the mainland. Because there’s no erosion, there is no material to replenish the beach meaning the beach level will become lower.
The limestone cliffs forming the back wall of the cove are vulnerable to mass movement and sometimes experience small slides and slumps. Longshore drift affects the bay carrying material mainly gravel from the south to the north of the beach.
However, this creates a strong backwash which removes sediment from the beach and can lead to erosion under the wall. Its coastline has examples of many erosional and depositional landforms.
The soft rock is made of clay and sands, and the hard rock is chalk and limestone. It is called the Jurassic Coast as it has lots of fossils dating back to the Jurassic period.
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. How do climate and geolgy influence geomorphic processes? Biological weathering caused by the vegetation on the top of the headland is also breaking up the rock.

Elsewhere, the cliffs are not covered by vegetation, so wet weather weakens them causing slumps. This is made saanage chalk which is a harder rock.
The area around Swanage is made up of bands of hard and soft rock. 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. A concordant coastline has the same type of rock along its length.
Chesil Beach is an example of a bar. Erosion is the dominant process in the bay with the beach losing material year on year. New timber groynes were installed on Swanage beach in and have reduced the loss of beach material. They trap material being transported by longshore drift to create larger beaches which stufy then absorb wave energy to reduce erosion rates.
Dorset – case study of a UK coastal landscape
The arch is gradually being worn away by mechanical, chemical and biological weathering. Concrete sea walls are in place along most of Swanage beach. The headland juts out into the sea, so it is more vulnerable to high-energy waves. How are geomorphic processes creating coastal landforms?

Chemical weathering and erosion are gradually wearing down these down. Then the cove widens where the softer clays have been more easily eroded.
Groynes Groynes are wooden or stone barries which are built at right angles to the coast. Dorsert is located on the southern coast of the UK.
Lulworth Cove is situated on the south coast of England, on a concordant coastline. It has been created by longshore drift. Sediment has been deposited over time to form a spit.
