How do climate and geolgy influence geomorphic processes? How are geomorphic processes creating coastal landforms? Longshore drift affects the bay carrying material mainly gravel from the south to the north of the beach. 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. Then the cove widens where the softer clays have been more easily eroded.
The Foreland, Old Harry and his Wife: It connects the Isle of Portland to the mainland. The soft rock is made of clay and sands, and the hard rock is chalk and limestone. Groynes Groynes are wooden or stone barries which are built at right angles to the coast. Behind the spit there is The Fleet, a lagoon.
The Foreland, Old Harry and his Wife: Behind the limestone is a layer of clay which is softer so more easily eroded. The headland is made out of chalk, a hard rock.
The area around Swanage is made up of bands of hard and soft rock. This means waves are slowed, reducing erosion and will help to protect proprties and cliffs.

This caused the formation of Old Harry, a stack. Concrete sea walls are in swanaye along most of Swanage beach. Towards the northern end of the bay the cliffs are covered in vegetation, stablising them and protecting them from erosion.
The spit has continued to join to the Isle of Portland. Erosion is the dominant process in the bay with the beach losing material year on year. Then the cove widens where the softer clays have been more easily eroded.
Sea wall Concrete sea walls are studdy place along most of Swanage beach. It has been created by longshore drift.
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. It is unusual as it has formed parallel to the coastline. Longshore drift affects the bay carrying material mainly gravel from the south to the north of the beach.
They reflect waves back out to sea preventing erosion of the cliff. How are geomorphic processes creating coastal landforms?
Over time Old Harry will collapse to form a stump. But, by stopping the movement of beach material along the coast swwnage further down the coast are becoming narrower and subject to more erosion due to reduced ability to absorb wave energy. The areas where the soft rock has eroded away, next to the headland, are called bays. Erosion by waves opened up a crack in the headland, stury then became a cave and eventually an arch.
An arch at the end of the headland has collpased to form a stack called Old Harry and a gfse called Old Harry’s Wife. Elsewhere, the cliffs are not covered by vegetation, so wet weather weakens them causing slumps.

Dorset is located in the south of England. New timber groynes were installed on Swanage beach in and have reduced the loss of beach material. Swanae is made of chalk which is a harder rock. A concordant coastline has the same type of rock along its length.
Swanage and Coastal Erosion
It is called the Jurassic Coast as it has lots of fossils dating back to the Jurassic period. Dorsert is located on the southern coast of the UK. The arch is gradually being worn away by mechanical, chemical and biological gcsw. Behind the spit there is The Fleet, a lagoon.
It connects the Isle of Portland to the mainland. Lulworth Cove is situated on the south coast of England, on a concordant coastline. However, this creates a strong backwash which removes sediment from the beach and can lead to erosion under the wall. The alternating bands of hard and soft rock run parallel to swabage coast. Groynes Groynes are wooden or stone barries which are built at right angles to the coast.
