SWANAGE BAY CASE STUDY GCSE

The headland is made out of chalk, a hard rock. There is also a risk for people from landslides and rockfalls. Elsewhere, the cliffs are not covered by vegetation, so wet weather weakens them causing slumps. The bands of soft rock erode more quickly than those of the more resistant hard rock leaving a section of land jutting out into the sea, called a headland. Longshore drift affects the bay carrying material mainly gravel from the south to the north of the beach.

Because there’s no erosion, there is no material to replenish the beach meaning the beach level will become lower. How is human activity, including mangement, working in combination with geomorphic processes to shape the landscape? This is made of chalk which is a harder rock. At the back of the cove is a band of more resistant chalk, so erosion is slower here. Dorset is located in the south of England. 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.

It has been created by longshore drift. As areas of the Dorset coast are being eroded, properities and infrastructure are at risk. It connects the Isle of Portland to the mainland. Elsewhere, the cliffs are not covered by vegetation, so wet weather weakens them causing slumps. They reflect waves back out swanzge sea preventing erosion of the cliff.

Beach replenishment 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. The limestone cliffs forming the back wall of the cove are vulnerable to mass movement and sometimes experience small slides and slumps. How do climate and geolgy influence geomorphic processes?

Chemical weathering and erosion are gradually wearing down these down. Towards the northern end of the bay the cliffs are covered in vegetation, stablising them and protecting them from erosion.

The soft rock is made of clay and sands, and the hard rock is chalk and limestone. Dorset is located in the south of England. Groynes Groynes are wooden or stone barries which are built at right angles to the coast. The spit has continued to join to the Isle of Portland. Biological weathering caused by the vegetation on the top of the headland is also breaking up the rock.

How is human activity, including mangement, working in combination with geomorphic processes to shape the landscape? This means waves are slowed, reducing cse and will help to protect proprties and cliffs. This is made of chalk which is a harder rock.

The areas where the soft rock has eroded away, next to the headland, are called bays. Erosion is the dominant process in the bay with the beach losing material year on year. Dorsert is located on the southern coast of the UK.

But, by stopping the sgudy of beach material along the coast beaches further down the coast are becoming narrower and subject to more erosion due to reduced ability to absorb wave energy.

There is also a risk for people from landslides and rockfalls. The headland juts out into the sea, so it is more vulnerable to high-energy waves. An arch at the end of the headland has collpased to form a stack called Old Harry and a stump called Old Harry’s Wife.

How are sgudy processes creating coastal landforms?

The headland is made out of chalk, a hard rock. Lulworth Cove is situated on the south coast of England, on a concordant coastline. Concrete sea walls are in place along most of Swanage beach.

Longshore drift affects the bay carrying material mainly gravel from the swanave to the north of the beach. Sea wall Concrete sea walls are in place along most of Swanage beach. New timber groynes were installed on Swanage beach in and have reduced stjdy loss of beach material. Sediment has been deposited over time to form a spit. The entrance to the cove is narrow where the waves have cut through weaknesses in the resistant limestone.

It is called the Jurassic Coast as it has lots of fossils dating back to the Jurassic period. Then the cove widens where the softer clays have been more easily eroded.
