Pulpit Rock (Isle Of Portland)
Pulpit Rock is a coastal feature at Portland Bill, the southern tip of the Isle of Portland, Dorset, England. Intended to have the appearance of an open bible leaning on a pulpit, Pulpit Rock was formed in the 1870s after a natural arch was cut away by quarrymen at Bill Quarry, and the leaning slab was added. As a quarrying relic, the rock is similar to that of Nicodemus Knob, another quarrying landmark on the island. Pulpit Rock has become a popular tourist attraction on the island and is often photographed. Despite the danger, for many decades it has been a popular place for tombstoning. Pulpit Rock is also a popular point for wrasse anglers. The British record Ballan wrasse was caught there in 1998 by Pete Hegg. The geological succession up from sea level is: Portland Cherty Series (up to the level of the neighbouring quarried platform), then Portland Freestone (the oolitic limestone quarried inland of Pulpit Rock), then a cap of thin-bedded limestones which are part of th ...

Pulpit Rock, Isle Of Portland, Dorset-9470
A pulpit is a raised stand for preachers in a Christian church. The origin of the word is the Latin ''pulpitum'' (platform or staging). The traditional pulpit is raised well above the surrounding floor for audibility and visibility, accessed by steps, with sides coming to about waist height. From the late medieval period onwards, pulpits have often had a canopy known as the sounding board, ''tester'' or ''abat-voix'' above and sometimes also behind the speaker, normally in wood. Though sometimes highly decorated, this is not purely decorative, but can have a useful acoustic effect in projecting the preacher's voice to the congregation below. Most pulpits have one or more book-stands for the preacher to rest his or her bible, notes or texts upon. The pulpit is generally reserved for clergy. This is mandated in the regulations of the Catholic Church, and several others (though not always strictly observed). Even in Welsh Nonconformism, this was felt appropriate, and in some ...

Succession (geology)
In geology, a succession is a series of strata or rock units in chronological order. Rock successions can be seen in cross sections through rock, for example in a road cut or cliff. With sedimentary layers of rocks, newer units will be above older units, except in cases of inversion.

Headlands Of Dorset
A headland, also known as a head, is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water. It is a type of promontory. A headland of considerable size often is called a cape.Whittow, John (1984). ''Dictionary of Physical Geography''. London: Penguin, 1984, pp. 80, 246. . Headlands are characterised by high, breaking waves, rocky shores, intense erosion, and steep sea cliff. Headlands and bays are often found on the same coastline. A bay is flanked by land on three sides, whereas a headland is flanked by water on three sides. Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast. Bays form when weak (less resistant) rocks (such as sands and clays) are eroded, leaving bands of stronger (more resistant) rocks (such as chalk, limestone, and granite) forming a headland, or peninsula. Through the deposition of sediment within the bay and the erosion of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Portland Stone
Portland stone is a limestone from the Tithonian stage of the Jurassic period quarried on the Isle of Portland, Dorset. The quarries are cut in beds of white-grey limestone separated by chert beds. It has been used extensively as a building stone throughout the British Isles, notably in major public buildings in London such as St Paul's Cathedral and Buckingham Palace. Portland Stone is also exported to many countries—being used for example in the United Nations headquarters in New York City. Geology Portland Stone formed in a marine environment, on the floor of a shallow, warm, sub-tropical sea probably near land (as evidenced by fossilized driftwood, which is not uncommon). When seawater is warmed by the sun, its capacity to hold dissolved gas is reduced; consequently, dissolved carbon dioxide (CO2) is released into the atmosphere as a gas. Calcium and bicarbonate ions within the water are then able to combine, to form calcium carbonate (CaCO3) as a precipitate. The proces ...

Chert
Chert () is a hard, fine-grained sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO2). Chert is characteristically of biological origin, but may also occur inorganically as a precipitation (chemistry), chemical precipitate or a diagenesis, diagenetic replacement, as in petrified wood. Chert is typically composed of the petrified remains of siliceous ooze, the biogenic sediment that covers large areas of the deep ocean floor, and which contains the silicon skeletal remains of diatoms, Dictyochales, silicoflagellates, and radiolarians. Precambrian cherts are notable for the presence of fossil cyanobacteria. In addition to Micropaleontology, microfossils, chert occasionally contains macrofossils. However, some chert is devoid of any fossils. Chert varies greatly in color (from white to black), but most often manifests as gray, brown, grayish brown and light green to rusty redW.L.

Ballan Wrasse
The ballan wrasse (''Labrus bergylta'') is a species of marine ray finned fish from the family Labridae, the wrasses. It is found in the eastern Atlantic Ocean, where it inhabits rocky areas. Like many wrasse species, it is a protogynous hermaphrodite—all fish start life as females, and some dominant fish later become males. It is used as a food fish in some areas and it is also finding use as a cleaner fish in the aquaculture of Atlantic salmon (''Salmo salar'') in northwestern Europe. Description The ballan wrasse is a large, heavy bodied wrasse with a relatively deep body and large head. It has a smallish mouth which is surrounded by thick, fleshy, rather wrinkled lips, and the jaws are armed with a single row of robust teeth which are sharp and pointed in young fish but blunter and more worn in older fish. It has a long dorsal fin which has 18–21 spines in its anterior portion and 9–13 branched rays in the rear part. The anal fin is markedly shorter and has three spines. ...

Portland Bill
Portland Bill is a narrow promontory (or bill) at the southern end of the Isle of Portland, and the southernmost point of Dorset, England. One of Portland's most popular destinations is Portland Bill Lighthouse. Portland's coast has been notorious for the number of shipwrecked vessels over the centuries. The dangerous coastline features shallow reefs and the Shambles sandbank, made more hazardous due to the strong Portland tidal race. The Bill is an important way-point for coastal traffic, and three lighthouses have been built to protect shipping. The original two worked as a pair from 1716, and they were replaced in 1906 by the current one. History From Roman times, beacon fires were lit to warn ships of the danger of the Bill. A petition to Trinity House was put forward for a lighthouse in the early 18th century, but Trinity House opposed it. They later conceded that a lighthouse was needed and George I granted the patent on 26 May 1716. Trinity House issued a lease to Willi ...

Wrasse
The wrasses are a family, Labridae, of marine fish, many of which are brightly colored. The family is large and diverse, with over 600 species in 81 genera, which are divided into 9 subgroups or tribes. They are typically small, most of them less than long, although the largest, the humphead wrasse, can measure up to . They are efficient carnivores, feeding on a wide range of small invertebrates. Many smaller wrasses follow the feeding trails of larger fish, picking up invertebrates disturbed by their passing. Juveniles of some representatives of the genera ''Bodianus'', ''Epibulus'', ''Cirrhilabrus'', ''Oxycheilinus'', and ''Paracheilinus'' hide among the tentacles of the free-living mushroom corals & ''Heliofungia actiniformis''. The word "wrasse" comes from the Cornish word ''wragh'', a lenited form of ''gwragh'', meaning an old woman or hag, via Cornish dialect ''wrath''. It is related to the Welsh ''gwrach'' and Breton ''gwrac'h''. Distribution Most wrasses inhabit the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tombstoning
Tombstoning (or cliff jumping) is the act of jumping in a straight, upright vertical posture into the sea or other body of water from a high jumping platform, such as a cliff, bridge or harbour edge. This posture of the body, resembling a tombstone, gives the activity its name. A safety advisory from the Government of the United Kingdom records that tombstoning has been taking place for "generations". In the United Kingdom between 2005 and 2015 there were 83 people injured and 20 people who died whilst tombstoning. Injuries and deaths It was reported that "Between June and August 007there were nine drowning or near misses as a result of people jumping from height into the water. Five were fatal, and impact injuries such as neck and spinal injuries were common in those who survived." In the UK between 2004 and 2008 there were 139 incidents of tombstoning where a rescue or emergency response was required. Spinal injuries occurred with 20% of these 139 incidents and 12 people died. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
