Aire Gap
Aire Gap is a pass through the Pennines in England formed by geologic faults and carved out by glaciers. The term is used to describe a geological division, a travel route, or a location that is an entry into the Aire river valley. Geology Geologically the Aire Gap lies between the Craven Fault and the limestone uplands of the Yorkshire Dales to the north and the Forest of Bowland and the millstone grit moors of the South Pennines. The South Pennines is the system between the Aire Gap and the Peak District.Encyclopædia Britannica The gap was formed by the dropping of the Craven Faults in the Carboniferous through Jurassic periods combined with glacial scouring by ice sheets in the Pleistocene Ice Age. The Aire Gap splits the Pennines into north and south by allying with the River Ribble. The Pennine chain is divided into two sections by the Aire Gap formed by the River Aire flowing south, a member of the Humber basin, and the Ribble flowing west and entering the Irish sea. ...

Sheep Pasture Near Cat Gill Wood - Geograph
Sheep or domestic sheep (''Ovis aries'') are domesticated, ruminant mammals typically kept as livestock. Although the term ''sheep'' can apply to other species in the genus ''Ovis'', in everyday usage it almost always refers to domesticated sheep. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female is referred to as a ''ewe'' (), an intact male as a ''ram'', occasionally a ''tup'', a castrated male as a ''wether'', and a young sheep as a ''lamb''. Sheep are most likely descended from the wild mouflon of Europe and Asia, with Iran being a geographic envelope of the domestication center. One of the earliest animals to be domesticated for agricultural purposes, sheep are raised for fleeces, meat (lamb, hogget or mutton) and milk. A sheep's wool is the most widely used animal fiber, and is usually harvested by shearing. In Commonw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leeds And Liverpool Canal
The Leeds and Liverpool Canal is a canal in Northern England, linking the cities of Leeds and Liverpool. Over a distance of , crossing the Pennines, and including 91 locks on the main line. The Leeds and Liverpool Canal has several small branches, and in the early 21st century a new link was constructed into the Liverpool docks system. History Background In the mid-18th century the growing towns of Yorkshire, including Leeds, Wakefield and Bradford, were trading increasingly. While the Aire and Calder Navigation improved links to the east for Leeds, links to the west were limited. Bradford merchants wanted to increase the supply of limestone to make lime for mortar and agriculture using coal from Bradford's collieries and to transport textiles to the Port of Liverpool. On the west coast, traders in the busy port of Liverpool wanted a cheap supply of coal for their shipping and manufacturing businesses and to tap the output from the industrial regions of Lancashire.

Thomas Dunham Whitaker
Thomas Dunham Whitaker (1759–1821) was an English clergyman and topographer. Life Born at Raynham, Norfolk, on 8 June 1759, he was the son of William Whitaker (1730–1782), curate of Raynham, Norfolk, and his wife Lucy, daughter of Robert Dunham, and widow of Ambrose Allen. In 1760 his father moved to his ancestral house at Holme, in the township of Cliviger, Lancashire, and the boy was in November 1766 placed under the care of the Rev. John Shaw of Rochdale. In November 1774, after spending a short time with the Rev. William Sheepshanks of Grassington in Craven, he was admitted to St John's College, Cambridge, and went into residence in October 1775. He took the degree of LL.B. in November 1781. His intention to enter the legal profession changed on the death of his father in the following year, when he settled at Holme. He was ordained in 1785, but remained without pastoral charge until 1797, when he was licensed to the perpetual curacy of Holme Chapel, where he had r ...

Pendle Water
Pendle Water is a minor river in Lancashire, England. Rising on Pendle Hill, Pendle Water cuts a deep valley between Barley Moor and Spence Hill where it feeds into the reservoirs of ''Upper'' and ''Lower Ogden''. Upon exiting the lower reservoir Pendle Water flows east through the villages of Barley and Roughlee before collecting Blacko Water which drains the Admergill Valley at Water Meetings near Wheathead, one mile west of the village of Blacko. The river then flows south through Higherford and Barrowford where it is joined by Colne Water. It collects Walverden Water as it passes the site of Nelson and Colne College. From this point onwards, the river flows west past the ''Lomeshaye Industrial Estate'' alongside the Leeds and Liverpool Canal towards its confluence with the River Calder in Reedley Hallows, which is northwest of Burnley. Pendle Water once supplied water to the ''Burnley Water Treatment Works'' which is situated on Wood End Lane. Flooding Incidents On T ...

Hypsography
Hypsometry () is the measurement of the elevation and depth of features of the Earth's surface relative to mean sea level. On Earth, the elevations can take on either positive or negative (below sea level) values. The distribution is theorised to be bimodal due to the difference in density between the lighter continental crust and denser oceanic crust. On other planets within this solar system, elevations are typically unimodal, owing to the lack of oceans on those bodies. Hypsometric curve A hypsometric curve is a histogram or cumulative distribution function of elevations in a geographical area. Differences in hypsometric curves between landscapes arise because the geomorphic processes that shape the landscape may be different. When drawn as a 2-dimensional histogram, a hypsometric curve displays the elevation (''y'') on the vertical, y-axis and area above the corresponding elevation (''x'') on the horizontal or x-axis. The curve can also be shown in non-dimensional or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jurassic
The Jurassic ( ) is a geologic period and stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and is the only boundary between geological periods to remain formally undefined. By the beginning of the Jurassi ...

Peak District
The Peak District is an upland area in England at the southern end of the Pennines. Mostly in Derbyshire, it extends into Cheshire, Greater Manchester, Staffordshire, West Yorkshire and South Yorkshire. It includes the Dark Peak, where moorland is found and the geology is dominated by gritstone, and the White Peak, a limestone area with valleys and gorges. The Dark Peak forms an arc on the north, east and west sides; the White Peak covers central and southern tracts. The historic Peak District extends beyond the National Park, which excludes major towns, quarries and industrial areas. It became the first of the national parks of England and Wales in 1951. Nearby Manchester, Stoke-on-Trent, Derby and Sheffield send millions of visitors – some 20 million live within an hour's ride. Inhabited from the Mesolithic era, it shows evidence of the Neolithic, Bronze and Iron Ages. Settled by the Romans and Anglo-Saxons, it remained largely agricultural; mining arose in the Middle Ages ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest Of Bowland
The Forest of Bowland, also known as the Bowland Fells and formerly the Chase of Bowland, is an area of gritstone fells, deep valleys and peat moorland, mostly in north-east Lancashire, England, with a small part in North Yorkshire (however roughly half of the area falls into the area of the historic West Riding of Yorkshire). It is a western outlier of the Pennines. The Forest of Bowland was designated an Area of Outstanding Natural Beauty (AONB) in 1964. The AONB also includes a detached part known as the Forest of Pendle separated from the main part by the River Ribble, Ribble Valley, and anciently a royal forest with its own separate history. One of the best-known features of the area is Pendle Hill, which lies in Pendle Forest. There are more than 500 listed buildings and 18 scheduled monuments within the AONB. The Trough of Bowland is a pass connecting the valley of the River Wyre, Marshaw Wyre with that of Langden Brook, and dividing the upland core of Bowland into two ...

Yorkshire Dales
The Yorkshire Dales is an upland area of the Pennines in the historic county of Yorkshire, England, most of it in the Yorkshire Dales National Park created in 1954. The Dales comprise river valleys and the hills rising from the Vale of York westwards to the hilltops of the Pennine watershed. In Ribblesdale, Dentdale and Garsdale, the area extends westwards across the watershed, but most of the valleys drain eastwards to the Vale of York, into the Ouse and the Humber. The extensive limestone cave systems are a major area for caving in the UK and numerous walking trails run through the hills and dales. Etymology The word ''dale'', like ''dell'', is derived from the Old English word ''dæl''. It has cognates in the Nordic/ Germanic words for valley (''dal'', ''tal''), and occurs in valley names across Yorkshire and Northern England. Usage here may have been reinforced by Nordic languages during the time of the Danelaw. Most of the dales are named after their river or stream (e ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
