The British Isles are a group of islands in the North Atlantic off the north-western coast of continental Europe that consist of the islands of Great Britain, the Isle of Man, the Hebrides and over six thousand smaller isles. They have a total area of about 315,159 km2 and a combined population of 72 million, include two sovereign states, the Republic of Ireland, the United Kingdom of Great Britain and Northern Ireland; the islands of Alderney, Jersey and Sark, their neighbouring smaller islands, are sometimes taken to be part of the British Isles though, as islands off the coast of France, they do not form part of the archipelago. The oldest rocks in the group are in the north west of Scotland and North Wales and are 2.7 billion years old. During the Silurian period, the north-western regions collided with the south-east, part of a separate continental landmass; the topography of the islands is modest in scale by global standards. Ben Nevis rises to an elevation of only 1,345 metres, Lough Neagh, notably larger than other lakes in the island group, covers 390 square kilometres.
The climate is temperate marine, with warm summers. The North Atlantic drift brings significant moisture and raises temperatures 11 °C above the global average for the latitude; this led to a landscape, long dominated by temperate rainforest, although human activity has since cleared the vast majority of forest cover. The region was re-inhabited after the last glacial period of Quaternary glaciation, by 12,000 BC, when Great Britain was still part of a peninsula of the European continent. Ireland, which became an island by 12,000 BC, was not inhabited until after 8000 BC. Great Britain became an island by 5600 BC. Hiberni and Britons tribes, all speaking Insular Celtic, inhabited the islands at the beginning of the 1st millennium AD. Much of Brittonic-occupied Britain was conquered by the Roman Empire from AD 43; the first Anglo-Saxons arrived as Roman power waned in the 5th century, dominated the bulk of what is now England. Viking invasions began in the 9th century, followed by more permanent settlements and political change in England.
The Norman conquest of England in 1066 and the Angevin partial conquest of Ireland from 1169 led to the imposition of a new Norman ruling elite across much of Britain and parts of Ireland. By the Late Middle Ages, Great Britain was separated into the Kingdoms of England and Kingdom of Scotland, while control in Ireland fluxed between Gaelic kingdoms, Hiberno-Norman lords and the English-dominated Lordship of Ireland, soon restricted only to The Pale; the 1603 Union of the Crowns, Acts of Union 1707 and Acts of Union 1800 attempted to consolidate Britain and Ireland into a single political unit, the United Kingdom of Great Britain and Ireland, with the Isle of Man and the Channel Islands remaining as Crown Dependencies. The expansion of the British Empire and migrations following the Irish Famine and Highland Clearances resulted in the dispersal of some of the islands' population and culture throughout the world, a rapid depopulation of Ireland in the second half of the 19th century. Most of Ireland seceded from the United Kingdom after the Irish War of Independence and the subsequent Anglo-Irish Treaty, with six counties remaining in the UK as Northern Ireland.
The term "British Isles" is controversial in Ireland, where there are nationalist objections to its usage. The Government of Ireland does not recognise the term, its embassy in London discourages its use. Britain and Ireland is used as an alternative description, Atlantic Archipelago has seen limited use in academia; the earliest known references to the islands as a group appeared in the writings of sea-farers from the ancient Greek colony of Massalia. The original records have been lost. In the 1st century BC, Diodorus Siculus has Prettanikē nēsos, "the British Island", Prettanoi, "the Britons". Strabo used Βρεττανική, Marcian of Heraclea, in his Periplus maris exteri, used αἱ Πρεττανικαί νῆσοι to refer to the islands. Historians today, though not in absolute agreement agree that these Greek and Latin names were drawn from native Celtic-language names for the archipelago. Along these lines, the inhabitants of the islands were called the Πρεττανοί; the shift from the "P" of Pretannia to the "B" of Britannia by the Romans occurred during the time of Julius Caesar.
The Greco-Egyptian scientist Claudius Ptolemy referred to the larger island as great Britain and to Ireland as little Britain in his work Almagest. In his work, Geography, he gave these islands the names Alwion and Mona, suggesting these may have been names of the individual islands not known to him at the time of writing Almagest; the name Albion appears to have fallen out of use sometime after the Roman conquest of Great Britain, after which Britain became the more commonplace name for the island called Great Britain. The earliest known use of the phrase Brytish Iles in the English language is dated 1577 in a work by John Dee. Today, this name is seen by some as carrying imperialist overtones although it is still used. Other names used to describe the islands include the Anglo-Celtic Isles, Atlantic archipelago, British-Irish Isles and Ireland, UK
The Bowes Museum has a nationally renowned art collection and is situated in the town of Barnard Castle, County Durham, England. The museum contains paintings by El Greco, Francisco Goya, Jean-Honoré Fragonard and François Boucher, together with a sizable collection of decorative art, textiles, tapestries and costumes, as well as older items from local history; the early works of French glassmaker Émile Gallé were commissioned by Joséphine, wife of the founder John Bowes. A great attraction is the 18th-century Silver Swan automaton, which periodically preens itself, looks round and appears to catch and swallow a fish; the Bowes Museum was purpose-built as a public art gallery for John Bowes and his wife Joséphine Chevalier, Countess of Montalbo, who both died before it opened in 1892. Bowes was the illegitimate son of the 10th Earl of Strathmore and Kinghorne, it was designed with the collaboration of two architects, the French architect Jules Pellechet and John Edward Watson of Newcastle. The building, in a grand French style within landscaped gardens, an early account described it as "... some 500 feet in length by 50 feet high, is designed in the French style of the First Empire.
Its contents are priceless, consisting of unique Napoleon relics, splendid picture galleries, a collection of old china, not to be matched anywhere else in the world, jewels of incredible beauty and value. In scale it is just as gloriously inappropriate for the town to which it belongs as in style"; the building was begun in 1869 and was reputed to have cost £100,000. Bowes and his wife left a total of 800 paintings, their collection of European fine and decorative arts amounted to 15,000 pieces. A major redevelopment of the Bowes Museum began in 2005. To date, improvements have been made to visitor facilities; the three art galleries, on the second floor of the museum, were updated at the same time. The museum hosts an internationally significant programme of exhibitions featuring works by Monet, Turner, Gallé, William Morris, Toulouse-Lautrec; the BBC announced in 2013 that a Portrait of Olivia Boteler Porter was a unknown Anthony van Dyck painting. It had been found in the Bowes Museum storeroom by art historian Dr. Bendor Grosvenor who had observed it on-line at the Your Paintings web site.
The painting itself was covered in layers of varnish and dirt, had not been renovated. It was thought to be a copy, valued at between £3,000 to £5,000. Christopher Brown, director of the Ashmolean Museum, confirmed it was a van Dyck after it had been restored. Selection of paintings Charles E.

Metamorphism is the change of minerals or geologic texture in pre-existing rocks, without the protolith melting into liquid magma. The change occurs due to heat and the introduction of chemically active fluids; the chemical components and crystal structures of the minerals making up the rock may change though the rock remains a solid. Changes at or just beneath Earth's surface due to weathering or diagenesis are not classified as metamorphism. Metamorphism occurs between diagenesis, melting; the geologists who study metamorphism are known as "metamorphic petrologists." To determine the processes underlying metamorphism, they rely on statistical mechanics and experimental petrology. Three types of metamorphism exist: contact and regional. Metamorphism produced with increasing pressure and temperature conditions is known as prograde metamorphism. Conversely, decreasing temperatures and pressure characterize retrograde metamorphism. Metamorphic rocks can change without melting. Heat causes atomic bonds to break, the atoms move and form new bonds with other atoms, creating new minerals with different chemical components or crystalline structures, or enabling recrystallization.
When pressure is applied, somewhat flattened grains that orient in the same direction have a more stable configuration. The temperature lower limit on what is considered to be a metamorphic process is considered to be 100 – 200 °C; the upper boundary of metamorphic conditions is related to the onset of melting processes in the rock. The maximum temperature for metamorphism is 700 – 900 °C, depending on the pressure and on the composition of the rock. Migmatites are rocks formed at this upper limit, which contains pods and veins of material that has started to melt but has not segregated from the refractory residue. Since the 1980s it has been recognized that rocks are dry enough and of a refractory enough composition to record without melting "ultra-high" metamorphic temperatures of 900 – 1100 °C; the metamorphic process has to be over pressure of at least 100 mega pascals but below 300 mega pascals, the depth of 100 mega pascals varies depending on what type of rock is applying pressure. Regional or Barrovian metamorphism covers large areas of continental crust associated with mountain ranges those associated with convergent tectonic plates or the roots of eroded mountains.
Conditions producing widespread regionally metamorphosed rocks occur during an orogenic event. The collision of two continental plates or island arcs with continental plates produce the extreme compressional forces required for the metamorphic changes typical of regional metamorphism; these orogenic mountains are eroded, exposing the intensely deformed rocks typical of their cores. The conditions within the subducting slab as it plunges toward the mantle in a subduction zone produce regional metamorphic effects, characterized by paired metamorphic belts; the techniques of structural geology are used to unravel the collisional history and determine the forces involved. Regional metamorphism can be described and classified into metamorphic facies or metamorphic zones of temperature/pressure conditions throughout the orogenic terrane. Contact metamorphism occurs around intrusive igneous rocks as a result of the temperature increase caused by the intrusion of magma into cooler country rock; the area surrounding the intrusion where the contact metamorphism effects are present is called the metamorphic aureole.
Contact metamorphic rocks are known as hornfels. Rocks formed by contact metamorphism may not present signs of strong deformation and are fine-grained. Contact metamorphism is greater adjacent to the intrusion and dissipates with distance from the contact; the size of the aureole depends on the heat of the intrusion, its size, the temperature difference with the wall rocks. Dikes have small aureoles with minimal metamorphism whereas large ultramafic intrusions can have thick and well-developed contact metamorphism; the metamorphic grade of an aureole is measured by the peak metamorphic mineral which forms in the aureole. This is related to the metamorphic temperatures of pelitic or aluminosilicate rocks and the minerals they form; the metamorphic grades of aureoles are sillimanite hornfels, pyroxene hornfels. Magmatic fluids coming from the intrusive rock may take part in the metamorphic reactions. An extensive addition of magmatic fluids can modify the chemistry of the affected rocks. In this case the metamorphism grades into metasomatism.
If the intruded rock is rich in carbonate the result is a skarn. Fluorine-rich magmatic waters which leave a cooling granite may form greisens within and adjacent to the contact of the granite. Metasomatic altered aureoles can localize the deposition of metallic ore minerals and thus are of economic interest. A special type of contact metamorphism, associated with fossil fuel fires, is known as pyrometamorphism. Hydrothermal metamorphism is the result of the interaction of a rock with a high-temperature fluid of variable composition; the difference in composition between an existing rock and the invading fluid triggers a set of metamorphic and metasomatic reactions. The hydrothermal fluid may be magmatic, circulating ocean water. Convective circulation of hydrothermal fluids in the ocean floor basalts produces extensive hydrothermal metamorphism adjacent to spreading centers and other submarine volcanic areas
England is a country, part of the United Kingdom. It shares land borders with Wales to Scotland to the north-northwest; the Irish Sea lies west of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south; the country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Palaeolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century, since the Age of Discovery, which began during the 15th century, has had a significant cultural and legal impact on the wider world; the English language, the Anglican Church, English law – the basis for the common law legal systems of many other countries around the world – developed in England, the country's parliamentary system of government has been adopted by other nations.
The Industrial Revolution began in 18th-century England, transforming its society into the world's first industrialised nation. England's terrain is chiefly low hills and plains in central and southern England. However, there is upland and mountainous terrain in the west; the capital is London, which has the largest metropolitan area in both the United Kingdom and the European Union. England's population of over 55 million comprises 84% of the population of the United Kingdom concentrated around London, the South East, conurbations in the Midlands, the North West, the North East, Yorkshire, which each developed as major industrial regions during the 19th century; the Kingdom of England – which after 1535 included Wales – ceased being a separate sovereign state on 1 May 1707, when the Acts of Union put into effect the terms agreed in the Treaty of Union the previous year, resulting in a political union with the Kingdom of Scotland to create the Kingdom of Great Britain. In 1801, Great Britain was united with the Kingdom of Ireland to become the United Kingdom of Great Britain and Ireland.
In 1922 the Irish Free State seceded from the United Kingdom, leading to the latter being renamed the United Kingdom of Great Britain and Northern Ireland. The name "England" is derived from the Old English name Englaland, which means "land of the Angles"; the Angles were one of the Germanic tribes that settled in Great Britain during the Early Middle Ages. The Angles came from the Anglia peninsula in the Bay of Kiel area of the Baltic Sea; the earliest recorded use of the term, as "Engla londe", is in the late-ninth-century translation into Old English of Bede's Ecclesiastical History of the English People. The term was used in a different sense to the modern one, meaning "the land inhabited by the English", it included English people in what is now south-east Scotland but was part of the English kingdom of Northumbria; the Anglo-Saxon Chronicle recorded that the Domesday Book of 1086 covered the whole of England, meaning the English kingdom, but a few years the Chronicle stated that King Malcolm III went "out of Scotlande into Lothian in Englaland", thus using it in the more ancient sense.
According to the Oxford English Dictionary, its modern spelling was first used in 1538. The earliest attested reference to the Angles occurs in the 1st-century work by Tacitus, Germania, in which the Latin word Anglii is used; the etymology of the tribal name itself is disputed by scholars. How and why a term derived from the name of a tribe, less significant than others, such as the Saxons, came to be used for the entire country and its people is not known, but it seems this is related to the custom of calling the Germanic people in Britain Angli Saxones or English Saxons to distinguish them from continental Saxons of Old Saxony between the Weser and Eider rivers in Northern Germany. In Scottish Gaelic, another language which developed on the island of Great Britain, the Saxon tribe gave their name to the word for England. An alternative name for England is Albion; the name Albion referred to the entire island of Great Britain. The nominally earliest record of the name appears in the Aristotelian Corpus the 4th-century BC De Mundo: "Beyond the Pillars of Hercules is the ocean that flows round the earth.
In it are two large islands called Britannia. But modern scholarly consensus ascribes De Mundo not to Aristotle but to Pseudo-Aristotle, i.e. it was written in the Graeco-Roman period or afterwards. The word Albion or insula Albionum has two possible origins, it either derives from a cognate of the Latin albus meaning white, a reference to the white cliffs of Dover or from the phrase the "island of the Albiones" in the now lost Massaliote Periplus, attested through Avienus' Ora Maritima to which the former served as a source. Albion is now applied to England in a more poetic capacity. Another romantic name for England is Loegria, related to the Welsh word for England and made popular by its use in Arthurian legend; the earliest known evidence of human presence in the area now known as England was that of Homo antecessor, dating to approximate
The British Broadcasting Corporation is a British public service broadcaster. Its headquarters are at Broadcasting House in Westminster, it is the world's oldest national broadcasting organisation and the largest broadcaster in the world by number of employees, it employs over 20,950 staff in total. The total number of staff is 35,402 when part-time and fixed-contract staff are included; the BBC is established under a Royal Charter and operates under its Agreement with the Secretary of State for Digital, Culture and Sport. Its work is funded principally by an annual television licence fee, charged to all British households and organisations using any type of equipment to receive or record live television broadcasts and iPlayer catch-up; the fee is set by the British Government, agreed by Parliament, used to fund the BBC's radio, TV, online services covering the nations and regions of the UK. Since 1 April 2014, it has funded the BBC World Service, which broadcasts in 28 languages and provides comprehensive TV, online services in Arabic and Persian.
Around a quarter of BBC revenues come from its commercial arm BBC Studios Ltd, which sells BBC programmes and services internationally and distributes the BBC's international 24-hour English-language news services BBC World News, from BBC.com, provided by BBC Global News Ltd. From its inception, through the Second World War, to the 21st century, the BBC has played a prominent role in British culture, it is known colloquially as "The Beeb", "Auntie", or a combination of both. Britain's first live public broadcast from the Marconi factory in Chelmsford took place in June 1920, it was sponsored by the Daily Mail's Lord Northcliffe and featured the famous Australian soprano Dame Nellie Melba. The Melba broadcast caught the people's imagination and marked a turning point in the British public's attitude to radio. However, this public enthusiasm was not shared in official circles where such broadcasts were held to interfere with important military and civil communications. By late 1920, pressure from these quarters and uneasiness among the staff of the licensing authority, the General Post Office, was sufficient to lead to a ban on further Chelmsford broadcasts.
But by 1922, the GPO had received nearly 100 broadcast licence requests and moved to rescind its ban in the wake of a petition by 63 wireless societies with over 3,000 members. Anxious to avoid the same chaotic expansion experienced in the United States, the GPO proposed that it would issue a single broadcasting licence to a company jointly owned by a consortium of leading wireless receiver manufactures, to be known as the British Broadcasting Company Ltd. John Reith, a Scottish Calvinist, was appointed its General Manager in December 1922 a few weeks after the company made its first official broadcast; the company was to be financed by a royalty on the sale of BBC wireless receiving sets from approved domestic manufacturers. To this day, the BBC aims to follow the Reithian directive to "inform and entertain"; the financial arrangements soon proved inadequate. Set sales were disappointing as amateurs made their own receivers and listeners bought rival unlicensed sets. By mid-1923, discussions between the GPO and the BBC had become deadlocked and the Postmaster-General commissioned a review of broadcasting by the Sykes Committee.
The Committee recommended a short term reorganisation of licence fees with improved enforcement in order to address the BBC's immediate financial distress, an increased share of the licence revenue split between it and the GPO. This was to be followed by a simple 10 shillings licence fee with no royalty once the wireless manufactures protection expired; the BBC's broadcasting monopoly was made explicit for the duration of its current broadcast licence, as was the prohibition on advertising. The BBC was banned from presenting news bulletins before 19.00 and was required to source all news from external wire services. Mid-1925 found the future of broadcasting under further consideration, this time by the Crawford committee. By now, the BBC, under Reith's leadership, had forged a consensus favouring a continuation of the unified broadcasting service, but more money was still required to finance rapid expansion. Wireless manufacturers were anxious to exit the loss making consortium with Reith keen that the BBC be seen as a public service rather than a commercial enterprise.
The recommendations of the Crawford Committee were published in March the following year and were still under consideration by the GPO when the 1926 general strike broke out in May. The strike temporarily interrupted newspaper production, with restrictions on news bulletins waived, the BBC became the primary source of news for the duration of the crisis; the crisis placed the BBC in a delicate position. On one hand Reith was acutely aware that the Government might exercise its right to commandeer the BBC at any time as a mouthpiece of the Government if the BBC were to step out of line, but on the other he was anxious to maintain public trust by appearing to be acting independently; the Government was divided on how to handle the BBC but ended up trusting Reith, whose opposition to the strike mirrored the PM's own. Thus the BBC was granted sufficient leeway to pursue the Government's objectives in a manner of its own choosing; the resulting coverage of both striker and government viewpoints impressed millions of listeners who were unaware that the PM had broadcast to the nation from Reith's home, using one of Reith's sound bites inserted at the last moment
Upper Teesdale is a Site of Special Scientific Interest in the Teesdale district of west County Durham, England. It encompasses an extensive upland area that includes the headwaters of the River Tees and the surrounding catchment area upstream of the village of Langdon Beck; the site has a diverse mix of habitats dry heath, with wet heath and blanket mire in areas that are poorly drained. The SSSI is one of the most important botanical sites in Britain; the area supports internationally important populations of some wading birds and is home to several rare invertebrates. Within the SSSI are several locations that are of national importance geologically, including one of only two known outcrops of'sugar' limestone in Britain; the southern part of the SSSI coincides with the eastern portion of the Moor House-Upper Teesdale National Nature Reserve, designated a'Biosphere Reserve' by UNESCO. The entire area falls within the North Pennines Area of Outstanding Natural Beauty. Much of Upper Teesdale SSSI was designated as Upper Teesdale and Appleby Fells SSSI.
Following a substantial revision in 1990, most of the site was divided between two new SSSIs, Upper Teesdale in Durham and Appleby Fells in Cumbria. A small part was amalgamated with Moor House NNR to form a third SSSI, Moorhouse and Cross Fell, contiguous with the other two. At the same time, two further SSSIs, Mill Beck Wood and Moking Hurth Cave, were incorporated into Upper Teesdale SSSI and ceased to exist as separate entities
