Pennines
The Pennines, also known as the Pennine Chain or Pennine Hills, are an upland range mainly located in Northern England. Sometimes described as the "backbone of England" because of its length and position, the range runs from Derbyshire and Staffordshire in the north of the Midlands to Northumberland in North East England. From the Tyne Gap in the north, the range extends south through the North Pennines, Yorkshire Dales, South Pennines, and Peak District to end near the valley of the River Trent. The Border Moors and Cheviot Hills, which lie beyond the Tyne Gap, are included in some definitions of the range.
The range is divided into two by the Aire Gap, a wide pass formed by the valleys of the rivers Aire and Ribble. There are several spurs off the main Pennine range east into Greater Manchester and Lancashire, comprising the Rossendale Fells, West Pennine Moors, and Bowland Fells. The Howgill Fells and Orton Fells in Cumbria are also sometimes considered to be Pennine spurs. The Pennines are an important water catchment area, with numerous reservoirs in the head streams of the river valleys.
Most of the range is protected by national parks and national landscapes. Running north to south, and including the Cheviots, the range is within Northumberland National Park, the North Pennines National Landscape, the Yorkshire Dales National Park, Nidderdale National Landscape, the Forest of Bowland National Landscape, and the Peak District National Park. The only significant unprotected area is that between Skipton and Marsden.
Britain's oldest long-distance footpath, the 268-mile Pennine Way, runs along most of the Pennines.
Name
Various etymologies have proposed treating "Pennine" as a native Brittonic/ Welsh name related to pen-. It did not become a common name until the 18th century, and may instead derive from modern comparisons with the Apennine Mountains, which run down the middle of Italy in a similar fashion.Following an 1853 article by Arthur Hussey, it has become a common belief that the name derives from a passage in The Description of Britain, an infamous historical forgery concocted by Charles Bertram in the 1740s and accepted as genuine until the 1840s. In 2004, George Redmonds reassessed this, finding that numerous respected writers passed over the origin of the mountains' name in silence even in works dedicated to the topological etymology of Derbyshire and Lancashire. He found that the derivation from Bertram was widely believed and considered uncomfortable. In fact, Redmonds found repeated comparisons with the Italian Apennines going back at least as early as William Camden, many of whose placenames and ideas Bertram incorporated into his work. Bertram was responsible with popularizing the name against other contenders such as Daniel Defoe's "English Andes". His own form of the name was the "Pennine Alps", which today is used for a western section of the continental Alps. Those mountains derive their name from the Latin Alpes Pœninæ whose name has been variously derived from the Carthaginians, a local god, and Celtic peninus. The St. Bernard Pass was the pass used in the invasions of Italy by the Gallic Boii and Lingones in 390 BC. The etymology of the Apennines themselves—whose name first referred to their northern extremity and then later spread southward—is also disputed but is usually taken to derive from some form of Celtic pen or ben.
Various towns and geographical features within the Pennines have names of at least partly Celtic origin, including Pennington, Penrith, Pen-y-ghent, Pendle Hill, the River Eden, and Cumbria. More commonly, local names result from Anglo-Saxon and Norse settlements. In Yorkshire, Teesdale, and Cumbria, many words of Norse origin, not commonly used in standard English, are part of everyday speech: for example, gill/ghyll, beck, fell, and dale. Northumbrian/borders terms are used in South Tynedale, Weardale, and Allendale, such as burn, cleugh, hope, law and linn.
Geography
The northern Pennine range is bordered by the foothills of the Lake District, and uplands of the Howgill Fells, Orton Fells, Border Moors and Cheviot Hills. The West Pennine Moors, Rossendale Valley and Forest of Bowland are western spurs, the former two are in the South Pennines. The Howgill Fells and Orton Fells are sometimes considered to be part of the Pennines, both inside the Yorkshire Dales National Park. The Pennines are fringed by extensive lowlands including the Eden Valley, West Lancashire Coastal Plain, Cheshire Plain, Vale of York, Humberhead Levels and the Midland Plains.The main range of the Pennines start from its southern end at the Weaver Hills in the Peak District. The southern foothills of the range merge into the valley and basin of the River Trent, separating the range from the Midland Plains to the south. The Pennines continue northwards across the Peak District and adjoin the South Pennines approximately around the Tame Valley, Standedge and Holme Valley. The South Pennines are separated from the Forest of Bowland by the Ribble Valley, and include the Rossendale Valley and West Pennine Moors in the west. The range continues further north into the Aire Gap which separates the Yorkshire Dales from the South Pennines to the south and the Forest of Bowland to the southwest. The main range then continues northwards across the Yorkshire Dales to the Stainmore Gap where it adjoins the North Pennines. The range continues into its northern end at the Tyne Gap, separating it from the Border Moors and Cheviot Hills across the Anglo-Scottish border.
Although the Pennines cover the area between the Peak District and the Tyne Gap, the Pennine Way affects perceptions of the southern and northern extents of the defined area. The southern end of the Pennines is said to be in the High Peak of Derbyshire at Edale, the start of the Pennine Way, but the main range continues south across the Peak District to the Weaver Hills, with its foothills merging into the Trent Valley. This encompasses eastern Cheshire, northern and eastern Staffordshire, and southern Derbyshire. Conversely, the Border Moors and Cheviot Hills, separated by the Tyne Gap and Whin Sill to the south, along which run the A69 and Hadrian's Wall, and River Tweed to the north, are not part of the Pennines but, perhaps because the Pennine Way crosses them, they are treated as such.

Most of the Pennine landscape is characterised by upland areas of high moorland indented by more fertile river valleys, although the landscape varies in different areas. The Peak District consists of hills, plateaus and valleys, divided into the Dark Peak with moorlands and gritstone edges, and the White Peak with limestone gorges. The South Pennines is an area of hills and moorlands with narrow valleys between the Peak District and Yorkshire Dales. Bowland is dominated by a central upland landform of deeply incised gritstone fells covered with tracts of heather-covered peat moorland, blanket bog and steep-sided wooded valleys linking the upland and lowland landscapes. The landscape is higher and more mountainous in the Yorkshire Dales and North Pennines. The Yorkshire Dales are characterised by valleys, moorlands and fells while the North Pennines consist of plateaus, moorlands, fells, edges and valleys, with most of the higher peaks in the west.
Elevation
Rising less than, the Pennines are fells, with most of the mountainous terrain in the north. The highest point is Cross Fell in eastern Cumbria, at and other principal peaks in the North Pennines are Great Dun Fell, Mickle Fell, and Burnhope Seat. Principal peaks in the Yorkshire Dales include Whernside, Ingleborough, High Seat, Wild Boar Fell and Pen-y-ghent. Principal peaks in the Forest of Bowland include Ward's Stone, Fair Snape Fell, and Hawthornthwaite Fell. Terrain is lower towards the south and the only peaks which exceed are Kinder Scout and Bleaklow in the Peak District. Other principal peaks in the South Pennines and Peak District include Black Hill, Shining Tor, Pendle Hill, Black Chew Head, Rombalds Moor and Winter Hill.Drainage
For much of their length the Pennines are the main watershed in northern England, dividing east and west. The rivers Eden, Ribble, Dane and tributaries of the Mersey flow westwards towards the Irish Sea.On the eastern side of the Pennines, the rivers Tyne, Wear, and Tees all drain directly to the North Sea. The Swale, Ure, Nidd, Wharfe, Aire, Calder and Don all flow into the Yorkshire Ouse, and reach the sea through the Humber Estuary.
The River Trent flows around the southern end of the Pennines and northwards on the eastern side taking water from tributaries, principally the Dove and Derwent. The Trent drains the east and west sides of the southern Pennines, also reaching the North Sea through the Humber Estuary. The Trent and Ouse meet and enter the Humber at Trent Falls. Maximum discharge through the Humber can reach 1,500 m3/s.
Climate
According to the Köppen classification, the Pennines generally have a temperate oceanic climate like the rest of England, but the uplands have more precipitation, stronger winds and colder weather than the surrounding areas. Some of the higher elevations have a subpolar oceanic climate, which may border a tundra and subarctic climate in areas like Great Dun Fell.More snow falls on the Pennines than on surrounding lowland areas due to the elevation and distance from the coast; unlike lowland areas of England, the Pennines can have quite severe winters.
The northwest is amongst the wettest regions of England and much of the rain falls on the Pennines. The eastern side is drier than the west—the rain shadow shields northeast England from rainfall that would otherwise fall there.
Precipitation is important for the area's biodiversity and human population. Many towns and cities are located along rivers flowing from the range and in northwest England the lack of natural aquifers is compensated for by reservoirs.
Water has carved out limestone landscapes in the North Pennines, Yorkshire Dales and Peak District, with gorges and caves present in the Yorkshire Dales and Peak District. In some areas, precipitation has contributed to poor soils, resulting in part in moorland landscapes that characterize much of the range. In other areas where the soil has not been degraded, it has resulted in lush vegetation.
For the purpose of growing plants, the Pennines are in hardiness zones 7 and 8, as defined by the USDA. Zone 8 is common throughout most of the UK, and zone 7 is the UK's coldest hardiness zone. The Pennines, Scottish Highlands, Southern Uplands and Snowdonia are the only areas of the UK in zone 7.
