Marilyn (hill)
This is a list of Marilyn hills and mountains in the United Kingdom, Isle of Man and Republic of Ireland, Ireland by height. Lists of mountains and hills in the British Isles#Marilyns, Marilyns are defined as peaks with a topographic prominence, prominence of or more, regardless of height or any other merit (e.g. topographic isolation, as used in Lists of mountains and hills in the British Isles#Munros, Munros). Thus, Marilyns can be mountains, with a height above , or relatively small hills. there were 2,011 recorded Marilyns. Definition The Marilyn classification was created by Alan Dawson in his 1992 book ''The Relative Hills of Britain''. The name Marilyn was coined by Dawson as a punning contrast to the ''Munro'' classification of Scottish mountains above , but which has no explicit prominence threshold, being homophonous with (Marilyn) ''Marilyn Monroe, Monroe''.

County Londonderry
County Londonderry ( Ulster-Scots: ''Coontie Lunnonderrie''), also known as County Derry ( ga, Contae Dhoire), is one of the six counties of Northern Ireland, one of the thirty two counties of Ireland and one of the nine counties of Ulster. Before the partition of Ireland, it was one of the counties of the Kingdom of Ireland from 1613 onward and then of the United Kingdom after the Acts of Union 1800. Adjoining the north-west shore of Lough Neagh, the county covers an area of and today has a population of about 247,132. Since 1972, the counties in Northern Ireland, including Londonderry, have no longer been used by the state as part of the local administration. Following further reforms in 2015, the area is now governed under three different districts; Derry and Strabane, Causeway Coast and Glens and Mid-Ulster. Despite no longer being used for local government and administrative purposes, it is sometimes used in a cultural context in All-Ireland sporting and cultural even ...

Northern Ireland
Northern Ireland ( ga, Tuaisceart Éireann ; sco, label= Ulster-Scots, Norlin Airlann) is a part of the United Kingdom, situated in the north-east of the island of Ireland, that is variously described as a country, province or region. Northern Ireland shares an open border to the south and west with the Republic of Ireland. In 2021, its population was 1,903,100, making up about 27% of Ireland's population and about 3% of the UK's population. The Northern Ireland Assembly (colloquially referred to as Stormont after its location), established by the Northern Ireland Act 1998, holds responsibility for a range of devolved policy matters, while other areas are reserved for the UK Government. Northern Ireland cooperates with the Republic of Ireland in several areas. Northern Ireland was created in May 1921, when Ireland was partitioned by the Government of Ireland Act 1920, creating a devolved government for the six northeastern counties. As was intended, Northern Ireland ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hill
A hill is a landform that extends above the surrounding terrain. It often has a distinct Summit (topography), summit. Terminology The distinction between a hill and a mountain is unclear and largely subjective, but a hill is universally considered to be not as tall, or as Grade (slope), steep as a mountain. Geographers historically regarded mountains as hills greater than above sea level, which formed the basis of the plot of the 1995 film ''The Englishman who Went up a Hill but Came down a Mountain''. In contrast, hillwalkers have tended to regard mountains as peaks above sea level. The ''Oxford English Dictionary'' also suggests a limit of and Whittow states "Some authorities regard eminences above as mountains, those below being referred to as hills." Today, a mountain is usually defined in the UK and Ireland as any summit at least high, while the official UK government's definition of a mountain is a summit of or higher.

Above Sea Level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...

Sperrins
The Sperrins or Sperrin Mountains () are a range of mountains in Northern Ireland and one of the largest upland areas in Northern Ireland. The range stretches from Strabane eastwards to Slieve Gallion in Desertmartin and north towards Limavady, in the counties of Tyrone and Londonderry. The region has a population of some 150,000 and is a designated Area of Outstanding Natural Beauty. Features It has a distinctive glaciated landscape. The Glenshane Pass, part of the A6 Belfast to Derry road, is in the mountains and has notoriously bad weather in winter. Sawel Mountain is the highest peak in the Sperrins, and the seventh highest in Northern Ireland. Its summit rises to . Another of the Sperrins, Carntogher (464 m), towers over the Glenshane Pass. Geologically, the Sperrins are formed mostly from Precambrian metamorphic rocks, with some younger Ordovician igneous rocks in the southern flank of the range. The Mountains are very sparsely populated and provide habitat for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ignimbrite
Ignimbrite is a type of volcanic rock, consisting of hardened tuff. Ignimbrites form from the deposits of pyroclastic flows, which are a hot suspension of particles and gases flowing rapidly from a volcano, driven by being denser than the surrounding atmosphere. New Zealand geologist Patrick Marshall (1869-1950) coined the term ''ignimbrite'' from the Latin ''igni-'' [fire] and ''imbri-'' [rain]. Ignimbrites are made of a very poorly sorted mixture of volcanic ash (or tuff when Lithification, lithified) and pumice lapilli, commonly with scattered lithic fragments. The ash is composed of glass shards and crystal fragments. Ignimbrites may be loose and unconsolidated, or lithified (solidified) rock called lapilli-tuff. Near the volcanic source, ignimbrites often contain thick accumulations of lithic blocks, and distally, many show meter-thick accumulations of rounded cobbles of pumice. Ignimbrites may be white, grey, pink, beige, brown, or black depending on their composition and d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plateau
In geology and physical geography, a plateau (; ; ), also called a high plain or a tableland, is an area of a highland consisting of flat terrain that is raised sharply above the surrounding area on at least one side. Often one or more sides have deep hills or escarpments. Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, and erosion by water and glaciers. Plateaus are classified according to their surrounding environment as intermontane, piedmont, or continental. A few plateaus may have a small flat top while others have wide ones. Formation Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, Plate tectonics movements and erosion by water and glaciers. Volcanic Volcanic plateaus are produced by volcanic activity. The Columbia Plateau in the north-western United States is an example. They may be formed by upwelling of volcanic magma or extrusion of lava. The un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magherafelt
Magherafelt (, mˠaxəɾʲəˈfʲiːlt̪ˠə is a small town and civil parish in County Londonderry, Northern Ireland. It had a population of 8,805 at the 2011 Census. It is the biggest town in the south of the county and is the social, economic and political hub of the area. It is part of Mid-Ulster District. History Magherafelt has been documented as a town since 1425. An earlier name for the area was ''Teach Fíolta'' - ‘Fíolta’s (monastic) house’. This would suggest that there was a monastic settlement here under the leadership of Fíolta. The site of the medieval parish church may be marked by the ruins of a later church and graveyard at the bottom of Broad Street. The Salters Company of London was granted the surrounding lands in South Londonderry in the seventeenth century as part of the Plantation of Ulster. Subsequently, the town began to take on its current shape with a central diamond forming the heart of the town. During The Troubles in the late 20th c ...

Mountains And Hills Of County Londonderry
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable ...
