The Solent is a strait between the Isle of Wight and mainland Great Britain; the major historic ports of Southampton and Portsmouth lie inland of its shores. It is about 20 miles long and varies in width between 2+1⁄2 and 5 mi, although the Hurst Spit which projects 1+1⁄2 mi (2.4 km) into the Solent narrows the sea crossing between Hurst Castle and Colwell Bay to just over 1 mi (1.6 km).
The Needles are a row of three stacks of chalk that rise about 30 metres (98 ft) out of the sea off the western extremity of the Isle of Wight in the English Channel, United Kingdom, close to Alum Bay and Scratchell's Bay, and part of Totland, the westernmost civil parish of the Isle of Wight. The Needles Lighthouse stands at the outer, western end of the formation. Built in 1859, it has been automated since 1994. The waters and adjoining seabed form part of the Needles Marine Conservation Zone and the Needles along with the shore and heath above are part of the Headon Warren and West High Down Site of Special Scientific Interest.
The Jurassic Coast is a World Heritage Site on the English Channel coast of southern England. It stretches from Exmouth in East Devon to Studland Bay in Dorset, a distance of about 96 miles (154 km), and was inscribed on the World Heritage List in mid-December 2001.
A stack or sea stack is a geological landform consisting of a steep and often vertical column or columns of rock in the sea near a coast, formed by wave erosion. Stacks are formed over time by wind and water, processes of coastal geomorphology. They are formed when part of a headland is eroded by hydraulic action, which is the force of the sea or water crashing against the rock. The force of the water weakens cracks in the headland, causing them to later collapse, forming free-standing stacks and even a small island. Without the constant presence of water, stacks also form when a natural arch collapses under gravity, due to sub-aerial processes like wind erosion. Erosion causes the arch to collapse, leaving the pillar of hard rock standing away from the coast—the stack. Eventually, erosion will cause the stack to collapse, leaving a stump. Stacks can provide important nesting locations for seabirds, and many are popular for rock climbing.
Studland is a village and civil parish on the Isle of Purbeck in Dorset, England. The village is located about 2 miles (3.2 km) north of the town of Swanage, over a steep chalk ridge, and 3 miles (4.8 km) south of the South East Dorset conurbation at Sandbanks, from which it is separated by Poole Harbour. The parish includes Brownsea Island within the harbour. In the 2011 census the parish had 182 households and a population of 425, though many of the houses in the village are holiday homes, second homes, or guest houses, and the village's population varies depending upon the season.
The Isle of Purbeck is a peninsula in Dorset, England. It is bordered by water on three sides: the English Channel to the south and east, where steep cliffs fall to the sea; and by the marshy lands of the River Frome and Poole Harbour to the north. Its western boundary is less well defined, with some medieval sources placing it at Flower's Barrow above Worbarrow Bay. John Hutchins, author of The History and Antiquities of the County of Dorset, defined Purbeck's western boundary as the Luckford Lake steam, which runs south from the Frome. According to writer and broadcaster Ralph Wightman, Purbeck "is only an island if you accept the barren heaths between Arish Mell and Wareham as cutting off this corner of Dorset as effectively as the sea." The most southerly point is St Alban's Head.
Durdle Door is a natural limestone arch on the Jurassic Coast near Lulworth in Dorset, England. It is privately owned by the Weld Family who own the Lulworth Estate, but it is also open to the public.
Ballard Down is an area of chalk downland on the Purbeck Hills in the English county of Dorset. The hills meet the English Channel here, and Ballard Down forms a headland, Ballard Point, between Studland Bay to the north and Swanage Bay to the south. The chalk here forms part of a system of chalk downlands in southern England, and once formed a continuous ridge between what is now west Dorset and the present day Isle of Wight. Old Harry Rocks, just offshore from the dip slope of the down, and The Needles on the westernmost tip of the Isle of Wight, are remnants of this ridge. The scarp slope of the down faces south, over Swanage, meeting the sea as Ballard Cliff.
Purbeck was a local government district in Dorset, England. The district was named after the Isle of Purbeck, a peninsula that forms a large proportion of the district's area. However, it extended significantly further north and west than the traditional boundary of the Isle of Purbeck which is the River Frome. The district council was based in the town of Wareham, which is itself north of the Frome.
Dorset is a county in South West England on the English Channel coast. Covering an area of 2,653 square kilometres (1,024 sq mi); it borders Devon to the west, Somerset to the north-west, Wiltshire to the north-east, and Hampshire to the east. The great variation in its landscape owes much to the underlying geology, which includes an almost unbroken sequence of rocks from 200 to 40 million years ago (Mya) and superficial deposits from 2 Mya to the present. In general, the oldest rocks appear in the far west of the county, with the most recent (Eocene) in the far east. Jurassic rocks also underlie the Blackmore Vale and comprise much of the coastal cliff in the west and south of the county; although younger Cretaceous rocks crown some of the highpoints in the west, they are mainly to be found in the centre and east of the county.
The Purbeck Hills, also called the Purbeck Ridge or simply the Purbecks, are a ridge of chalk downs in Dorset, England. It is formed by the structure known as the Purbeck Monocline. The ridge extends from Lulworth Cove in the west to Old Harry Rocks in the east, where it meets the sea. The hills are part of a system of chalk downlands in southern England formed from the Chalk Group which also includes Salisbury Plain and the South Downs. For most of their length the chalk of the Purbeck Hills is protected from coastal erosion by a band of resistant Portland limestone. Where this band ends, at Durlston Head, the clay and chalk behind has been eroded, creating Poole Bay and the Solent. The ridge of steeply dipping chalk that forms the Purbeck Hills continues further east on the Isle of Wight.
The geology of Hampshire in southern England broadly comprises a gently folded succession of sedimentary rocks dating from the Cretaceous and Palaeogene periods. The lower (early) Cretaceous rocks are sandstones and mudstones whilst those of the upper (late) Cretaceous are the various formations which comprise the Chalk Group and give rise to the county's downlands. Overlying these rocks are the less consolidated Palaeogene clays, sands, gravels and silts of the Lambeth, Thames and Bracklesham Groups which characterise the Hampshire Basin.
Worbarrow Bay is a large broad and shallow bay just to the east of Lulworth Cove on the Isle of Purbeck, Dorset, England.
Peveril Point is a headland on the east-facing coast of the Isle of Purbeck in Dorset, England, and is part of the town of Swanage. It forms the southern end of Swanage Bay. It is located at 50°36.43′N01°56.69′W OS Grid Ref: SZ 041 787.
The Hampshire Basin is a geological basin of Palaeogene age in southern England, underlying parts of Hampshire, the Isle of Wight, Dorset, and Sussex. Like the London Basin to the northeast, it is filled with sands and clays of Paleocene and younger ages and it is surrounded by a broken rim of chalk hills of Cretaceous age.
Cow Corner is the north-western end of Worbarrow Bay, a small secluded bay on the south coast of the Isle of Purbeck in Dorset, England.
Parson's Barn is a large sea-level cavern below the Ballard Point cliffs, between Studland and Swanage bays in the English Channel. Ballard Point is the headland of the Ballard Downs, an area of chalk downland, on the Isle of Purbeck in Dorset, southern England.
The Purbeck Monocline is a geological fold in southern England. The term 'fold' is used in geology when one or more originally flat sedimentary strata surfaces are bent or curved as a result of plastic deformation. A monocline is a step-like fold, in which one limb is roughly horizontal. The Purbeck Monocline was formed during the late Oligocene and early Miocene epochs, about 30 million years ago. It is the northernmost 'ripple' of the Alpine Orogeny.
Dorset is a county located in the middle of the south coast of England. It lies between the latitudes 50.512°N and 51.081°N and the longitudes 1.682°W and 2.958°W, and occupies an area of 2,653 km2. It spans 90 kilometres (56 mi) from east to west and 63 kilometres (39 mi) from north to south.
The Pinnacles are two chalk formations, including a stack and a stump, located near Handfast Point, on the Isle of Purbeck in Dorset, southern England.
