LULWORTH COVE GEOGRAPHY CASE STUDY A LEVEL

Take a look at our new resources in the shop Dismiss. The bedrock around Lulworth cove is sedimentary. A chalk cliff face is at the back of the cove. The area is extremely important for its geology, with some of the finest folding strata in Europe” BBC, Lulworth Cove 10 facts about Lulworth Cove:

However, this creates a strong backwash which removes sediment from the beach and can lead to erosion under the wall. This caused the formation of Old Harry, a stack. Home Coastal Processes Fact file: Typhoon Haiyan Case Study. Sediment has been deposited over time to form a spit. Take a look at our new resources in the shop Dismiss. Its coastline has examples of many erosional and depositional landforms.

North of Swanage, the chalk outcrop creates the headland which includes Old Harry Rocks.

At the back of the cove is a band of more resistant chalk, so erosion is slower here. Skip to main content.

It has been created by longshore drift. Dorsert is located on the southern coast of the UK. Quick revise Discordant coastline occurs where bands of differing rock type run perpendicular to the coast. The Portland limestone is resistant to erosion; then to the north lulwortj is Swanage Bay where the rock type is a softer greensand. Chesil Beach is an example of a bar.

Landforms of the South Coast.

Dorset – case study of a UK coastal landscape

Because there’s no erosion, there is no material to replenish the beach meaning the beach level will become lower. Pin It on Pinterest. 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.

  PHYSICS HOMEWORK #141

The area around Swanage is made up of bands of hard and soft rock. Its coastline has examples of many erosional and depositional landforms. The landscape around the cove is constantly changing — it continues to evolve behind a narrow Portland Stone entrance whilst the softer chalk covf are eroded.

My case studies – Coasts

Coastlines where the geology alternates between bands of hard and soft rock which are perpendicular to the shore are called discordant coastlines. Dorset is located in the south of England.

Folding at Lulworth Cove. Concrete sea walls are in place along most of Swanage beach. They now lie with the oldest rock, the Portland Stone, nearest the sea and the youngest stone, chalk, furthest inland.

But, by stopping the movement 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.

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. The differing resistance to erosion leads to the formation of headlands and bays. Sthdy process limits the energy of the waves, therefore creating a calm environment which is popular with tourists who use the beach and for fishing boats in the cove.

It is unusual as it has formed parallel to the coastline. Chesil Beach Fact file: The entrance is a breach in the very resistant Portland Stone that about metres wide. Each year more than Over time Old Harry will geograpby to form a beography. How is human activity, including mangement, working in combination with geomorphic processes to shape the landscape? This means it was originally laid down flat with layers of rock forming on top of each other.

Lulworth Cove Coursework

Towards the northern end of the bay the cliffs are covered in vegetation, stablising them and protecting them from erosion. The arch is gradually being worn away by mechanical, chemical and biological weathering. This creates a cove which is a circular area of water with a relatively narrow entrance way from the sea. This means waves are slowed, reducing erosion and will help to protect proprties and cliffs.

They trap material being transported by longshore drift to create larger beaches which can then absorb wave energy to reduce erosion rates.
