How was Lulworth cove formed?
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 was Lulworth cove formed a level?
The cove has formed as a result of bands of rock of alternating geological resistance running parallel to the coastline (a concordant coastline). On the seaward side the clays and sands have been eroded away. A narrow (less than 30 metres (98 ft)) band of Portland limestone rocks forms the shoreline.
How was Durdle Door in Dorset formed?
South | Durdle Door Durdle Door is a huge, natural limestone arch on the spectacular Dorset coast. Located on the Jurassic coastline between Swanage and Weymouth, the arch was formed when less resilient rock was eroded by the sea. The beach is a narrow strand of mixed shingle, gravel and sand.
How was stair hole formed?
Stair Hole is the big hole in the spine of hard Portland limestone that faces out to sea. 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.
How is Lulworth cove formed GCSE?
Lulworth Cove was formed by the sea breaking through a comparatively thin layer of hard Portland Stone that runs parallel to the shoreline. Once through, the action of the waves allowed much softer clays to be eroded more rapidly and extensively.
Is Lulworth Cove a headland and bay?
Lulworth Cove is a landform created by coastal erosion on the Dorset Coast. Lulworth Cove is a bay located next to the village of Lulworth.
Why does Durdle Door have a hole?
The arch has formed on a concordant coastline where bands of rock run parallel to the shoreline. Originally a band of resistant Portland limestone ran along the shore, the same band that appears one mile along the coast forming the narrow entrance to Lulworth Cove.
What has happened at Stair Hole?
In Stair Hole there has been some cliff erosion and rock fracture in 2011. At about the same time small cliff falls were noted in the Chalk at the back of Lulworth Cove (see the Lulworth Cove webpage.) It is in the western part of Stair Hole, where the sea has direct access.
How was Dorset coast formed?
The rocks of the Jurassic Coast formed from layers of sediment that were deposited, tilted and eroded during the Mesozoic. More recent erosion, in the Quaternary, formed the coastal landscape as we know it today, leaving outcrops that represent roughly 185 million years of geologic activity.
What are the features of Lulworth Cove Dorset?
Lulworth Cove is one of Dorset’s most picturesque and popular coastal haunts. Carved out of the rocky coastline purely by the action of the sea, it is also one of several characteristic geological features in the area. Others include Stair Hole, the iconic Durdle Door and the “Fossil Forest”.
How did the rock form in Lulworth Cove?
Lulworth Cove was formed by the sea breaking through a comparatively thin layer of hard Portland Stone that runs parallel to the shoreline. Once through, the action of the waves allowed much softer clays to be eroded more rapidly and extensively.
What kind of landforms are found on the Dorset coast?
Erosional landforms include headlands, bays, caves, arches, stacks, stumps and wave-cut platforms. There are also depositional landforms such as beaches, spits and bars. Dorset is located in the south of England. Its coastline has examples of many erosional and depositional landforms.
What kind of rock is at Swanage Dorset?
The area around Swanage is made up of bands of hard and soft rock. The soft rock is made of clay and sands, and the hard rock is chalk and limestone. 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.
