South Pennines 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 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, 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. 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.
Climate , Yorkshire Dales According to the
Köppen classification, the Pennines generally have a temperate
oceanic climate (
Cfb) 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 (
Cfc), which may border a
tundra (
ET) and
subarctic climate (
Dfc) 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. ==Geology==
