Dry Valley
A dry valley may develop on many kinds of permeable rock, such as limestone and chalk, or sandy terrains that do not regularly sustain surface water flow. Such valleys do not hold surface water because it sinks into the permeable bedrock. There are many examples of chalk dry valleys along the North and South Downs in Southern England. Notably the National Trust-owned Devil's Dyke near Brighton covers some of downland scarp, and includes the deepest dry valley in the world – created when melting water eroded the chalk downland to the permafrost layer after the last ice age. The three-quarter mile long curved dry valley is around in height and attracts tourists with its views of Sussex, Hampshire and Kent. Other examples include the Alkham Valley near Dover, and the Hartley Bottom and Fawkham valleys near Dartford in north Kent. There are many examples of limestone dry valleys in the Peak District and the Yorkshire Wolds. A notable example is the valley of the River Manifold ...

Dover
Dover () is a town and major ferry port in Kent, South East England. It faces France across the Strait of Dover, the narrowest part of the English Channel at from Cap Gris Nez in France. It lies south-east of Canterbury and east of Maidstone. The town is the administrative centre of the Dover District and home of the Port of Dover. Archaeological finds have revealed that the area has always been a focus for peoples entering and leaving Great Britain, Britain. The name derives from the River Dour that flows through it. In recent times the town has undergone transformations with a high-speed rail link to London, new retail in town with St James' area opened in 2018, and a revamped promenade and beachfront. This followed in 2019, with a new 500m Pier to the west of the Harbour, and new Marina unveiled as part of a £330m investment in the area. It has also been a point of destination for many illegal migrant crossings during the English Channel migrant crossings (2018-present) ...

Permafrost
Permafrost is ground that continuously remains below 0 °C (32 °F) for two or more years, located on land or under the ocean. Most common in the Northern Hemisphere, around 15% of the Northern Hemisphere or 11% of the global surface is underlain by permafrost, with the total area of around 18 million km2. This includes substantial areas of Alaska, Greenland, Canada and Siberia. It can also be located on mountaintops in the Southern Hemisphere and beneath ice-free areas in the Antarctic. Permafrost does not have to be the first layer that is on the ground. It can be from an inch to several miles deep under the Earth's surface. It frequently occurs in ground ice, but it can also be present in non-porous bedrock. Permafrost is formed from ice holding various types of soil, sand, and rock in combination. Permafrost contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide, making tundra soil a carbon sink. As global war ...

Periglacial
Periglaciation (adjective: "periglacial", also referring to places at the edges of glacial areas) describes geomorphic processes that result from seasonal thawing of snow in areas of permafrost, the runoff from which refreezes in ice wedges and other structures. "Periglacial" suggests an environment located on the margin of past glaciers. However, freeze and thaw cycles influence landscapes outside areas of past glaciation. Therefore, periglacial environments are anywhere that freezing and thawing modify the landscape in a significant manner. Tundra is a common ecological community in periglacial areas. History Periglaciation became a distinct subject within the study of geology after Walery Łoziński, a Polish geologist, introduced the term in 1909. Łoziński drew upon the early work of Johan Gunnar Andersson. According to Alfred Jahn, his introduction of his work at the 1910 International Geological Congress held in Stockholm caused significant discussion. In the field trip ...

Water Table
The water table is the upper surface of the zone of saturation. The zone of saturation is where the pores and fractures of the ground are saturated with water. It can also be simply explained as the depth below which the ground is saturated. The water table is the surface where the water pressure head is equal to the atmospheric pressure (where gauge pressure = 0). It may be visualized as the "surface" of the subsurface materials that are saturated with groundwater in a given vicinity. The groundwater may be from precipitation or from groundwater flowing into the aquifer. In areas with sufficient precipitation, water infiltrates through pore spaces in the soil, passing through the unsaturated zone. At increasing depths, water fills in more of the pore spaces in the soils, until a zone of saturation is reached. Below the water table, in the phreatic zone (zone of saturation), layers of permeable rock that yield groundwater are called aquifers. In less permeable soils, such as ...

Wetton, Staffordshire
Wetton is a village in the Peak District National Park, North Staffordshire, at the top of the east side of the Manifold Valley. The population recorded in the 2001 Census was 157. At the time of the 2011 Census the population was recorded under Ilam. This article describes the location, some of the main features of the village, and a number of places of historical or general interest in or near the village. These include Long Low, Wetton, a prehistoric burial site unique to England. Because the post town is Ashbourne, Derbyshire, many sources of tourist information wrongly describe Wetton as being in Derbyshire. Location Wetton is a small village in the Staffordshire Peak District. It is about 2 miles west of Alstonfield and 8½ miles east of Leek. It stands high above the Manifold valley and contains mostly stone-built properties. The village has an inn, and a church, part of which dates back to the 14th century. The church is unusual in that it has an external staircas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Manifold
The River Manifold is a river in Staffordshire, England. It is a tributary of the River Dove (which also flows through the Peak District, forming the boundary between Derbyshire and Staffordshire). The Manifold rises at Flash Head just south of Buxton near Axe Edge, at the northern edge of the White Peak, known for its limestone beds. It continues for before it joins the Dove. For part of its course, it runs underground (except when in spate), from Wetton Mill to Ilam. During this section it is joined by its major tributary, the River Hamps. Villages on the river include Longnor, Hulme End and Ilam. Its name may come from Anglo-Saxon ''manig-fald'' = "many folds", referring to its meanders. Manifold Way The Manifold Way is an long-distance footpath from Hulme End to Waterhouses, along the former route of the narrow-gauge (2' 6") Leek and Manifold Valley Light Railway which operated between 1904 and 1934. Opened in July 1937 after the LMS handed over the trackbed t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yorkshire Wolds
The Yorkshire Wolds are low hills in the counties of the East Riding of Yorkshire and North Yorkshire in north-eastern England. The name also applies to the district in which the hills lie. On the western edge, the Wolds rise to an escarpment which then drops sharply to the Vale of York. The highest point on the escarpment is Bishop Wilton Wold (also known as Garrowby Hill), which is above sea level. To the north, on the other side of the Vale of Pickering, lie the North York Moors, and to the east the hills flatten into the plain of Holderness. The largest town in the Wolds is Driffield, with other places including Pocklington, Thixendale and Kilham, the original 'capital' of the Wolds. The highest village on the Yorkshire Wolds is Fridaythorpe at above sea level. The market town of Beverley lies on the eastern slopes, along with the civil parish of Molescroft. Geology The hills are formed from a series of pure marine limestones formed during the Cretaceous period, kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peak District
The Peak District is an upland area in England at the southern end of the Pennines. Mostly in Derbyshire Derbyshire ( ) is a ceremonial county in the East Midlands, England. It includes much of the Peak District National Park, the southern end of the Pennine range of hills and part of the National Forest. It borders Greater Manchester to the nor ..., 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 v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dartford
Dartford is the principal town in the Borough of Dartford, Kent, England. It is located south-east of Central London and is situated adjacent to the London Borough of Bexley to its west. To its north, across the Thames estuary, is Thurrock in Essex, which can be reached via the Dartford Crossing. The town centre lies in a valley through which the River Darent flows and where the old road from London to Dover crossed: hence the name, from ''Darent + ford''. Dartford became a market town in medieval times and, although today it is principally a commuter town for Greater London, it has a long history of religious, industrial and cultural importance. It is an important rail hub; the main through-road now by-passes the town itself. Geography Dartford lies within the area known as the London Basin. The low-lying marsh to the north of the town consists of London Clay and the alluvium brought down by the two rivers—the Darent and the Cray—whose confluence is in this area. T ...
