Lulworth Cove in Dorset is a stunning, scallop-shaped cove which was formed approximately 10,000 years ago by the power of water. The landscape around the cove is constantly changing – it continues to evolve behind a narrow Portland Stone entrance whilst the softer chalk exposures are eroded.
How did the Lulworth Crumple form?
In this way the amazing folds that are the Lulworth Crumple were formed. … It’s been formed by sea erosion of a weakness in the rock, which is slowly, slowly producing a circular sea cove behind it that will one day, in the distant future look like Lulworth Cove, just over the other side of the headland.
Is Lulworth Cove erosional or depositional?

How is a cove formed?

How is a cove formed BBC Bitesize?
The soft rock is made of clay and sands, and the hard rock is chalk and limestone.

Sometimes the outer hard rock is punctured, allowing the sea to erode the softer rocks behind. This creates a cove, a circular area of water with a relatively narrow entrance from the sea. Lulworth Cove in Dorset is situated on a concordant coastline.
How are spits formed?A spit is an extended stretch of beach material that projects out to sea and is joined to the mainland at one end. Spits are formed where the prevailing wind blows at an angle to the coastline, resulting in longshore drift. An example of a spit is Spurn Head, found along the Holderness coast in Humberside.

What is special about Lulworth Cove?
Lulworth Cove is world famous for its unique geology and landforms including the Lulworth Crumple and Stair Hole. Open every day, we welcome thousands of people each year who come to enjoy the panoramic views and crystal clear waters on this stretch of the UNESCO World Heritage Site.

It is particularly well seen in the east side of Stair Hole. . . The Lulworth Crumples are minor folds within the north limb of the major monocline.
What type of landform is stair hole?
Stair Hole is a minor landform to the west of Lulworth Cove. It has formed due to the concordant nature of the coast (geological structure runs parallel to the coast), and shows how coves (shell-shaped bays) are likely to develop in their initial stages.
What sea is at Durdle Door?
In Man O’ War Bay, the small bay immediately east of Durdle Door, the band of Portland and Purbeck limestone has not been entirely eroded away, and is visible above the waves as Man O’War Rocks.

What is a recurved spit?
Hooked/Recurved spits. A spit whose end is curved landwards, into a bay or inlet. A hook or a recurve may form at the end of the spit. This is because wave refraction round the distal end transports and deposits sediment for a short distance in the landward direction.
How are spits bars and Tombolos formed?
A tombolo is formed when a spit connects the mainland coast to an island. A spit is a feature that is formed through deposition of material at coastlines. The process of longshore drift occurs and this moves material along the coastline. … Through this process material is constantly moved along the coastline.
How spits and bars form lagoons?
Bars, lagoons, and spits are different types of coastal features. These form when waves shift sand and pebbles along beaches. This process is called longshore drift. … Other long beaches continue out into the sea as narrow strips of land.

sandbar, also called Offshore Bar, submerged or partly exposed ridge of sand or coarse sediment that is built by waves offshore from a beach. Sand suspended in the backwash and in rip currents adds to the bar, as does some sand moving shoreward from deeper water. …
