Wolds
The Wolds is a term used in England to describe a range of hills which consists of open country overlying a base of limestone or chalk. Geography The Wolds comprise a series of low hills and steep valleys that are in the main underlain by calcareous (chalk and limestone) and sandstone rock, laid down in the Cretaceous and Jurassic periods. One exception to this is the North Leicestershire /South Nottinghamshire Wolds, which are underlain by sometimes chalky glacial till ('Oadby Till'). The characteristic open valleys of the Wolds were created during the last glacial period through the action of glaciation and meltwater. The chalk that underlies the Chalk Wolds Landscape Character Type extends from the Yorkshire Wolds to the south coast of England, in East Sussex and in Dorset. Geologically, the Lincolnshire Wolds is a continuation of the Yorkshire Wolds which runs through the East Riding of Yorkshire; the point at which the ranges of hill crosses the Humber is known as the Humber ...

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.

Lincolnshire Wolds
The Lincolnshire Wolds are a range of low hills in the county of Lincolnshire, England which run roughly parallel with the North Sea coast, from the Humber Estuary in the north-west to the edge of the Lincolnshire Fens in the south-east. They are a designated Area of Outstanding Natural Beauty (AONB), and the highest area of land in eastern England between Yorkshire and Kent.Ordnance Survey maps: Geology The Wolds are formed largely from a series of pure marine limestones formed during the Cretaceous period, known collectively as the Chalk Group. The chalk overlies a series of other sedimentary strata of late Jurassic/early Cretaceous age. The strata dip gently to the east and form a scarp which runs southeast from Barton upon Humber via Caistor before it loses its identity north of Spilsby. To the north of the Humber Gap, the same formations continue as the Yorkshire Wolds. The rock succession in stratigraphic order i.e. youngest/uppermost first, is this: *White Chalk Subgro ...

East Riding Of Yorkshire
The East Riding of Yorkshire, or simply East Riding or East Yorkshire, is a ceremonial county and unitary authority area in the Yorkshire and the Humber region of England. It borders North Yorkshire to the north and west, South Yorkshire to the south-west, and Lincolnshire to the south. The coastal towns of Bridlington, Hornsea and Withernsea are popular with tourists, the town of Howden contains Howden Minster, Market Weighton, Pocklington, Brough, Hedon and Driffield are market towns with markets held throughout the year and Hessle and Goole are important port towns for the county. The port city of Kingston upon Hull is an economic, transport and tourism centre which also receives much sea freight from around the world. The current East Riding of Yorkshire came into existence in 1996 after the abolition of the County of Humberside. The county's administration is in the ancient market town of Beverley. The landscape is mainly rural, consisting of rolling hills, valley ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Humber Gap
The Humber Gap is a term for the geographic gap between the roughly north–south running line of hills formed by the Yorkshire Wolds and the Lincolnshire Wolds, formed by the west–east running Humber Estuary. In the geological past the gap has formed part of an ice barrier due to glaciers during the ice age resulting in damming and formation of a 'Humber Lake', and also forms a geological division. In modern times the gap has formed a natural choice for transport routes, such as the railways. The Humber Bridge also crosses the Humber close to the gap. See also *Humberhead Levels: very heavily silted area formed west of the gap as a result of the damming of the gap, and subsequent lake formation *North Ferriby and South Ferriby South Ferriby is a village in North Lincolnshire, England. It is situated on the south bank of the Humber Estuary and west from the Humber Bridge. North Ferriby is directly opposite on the Estuary's north bank. Village population was 651 in ...

The Weald
The Weald () is an area of South East England between the parallel chalk escarpments of the North and the South Downs. It crosses the counties of Hampshire, Surrey, Sussex and Kent. It has three separate parts: the sandstone "High Weald" in the centre; the clay "Low Weald" periphery; and the Greensand Ridge, which stretches around the north and west of the Weald and includes its highest points. The Weald once was covered with forest, and its name, Old English in origin, signifies "woodland". The term is still used today, as scattered farms and villages sometimes refer to the Weald in their names. Etymology The name "Weald" is derived from the Old English ', meaning "forest" (cognate of German ''Wald'', but unrelated to English "wood", which has a different origin). This comes from a Germanic root of the same meaning, and ultimately from Indo-European. ''Weald'' is specifically a West Saxon form; '' wold'' is the Anglian form of the word. The Middle English form of the word i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cotswolds
The Cotswolds (, ) is a region in central-southwest England, along a range of rolling hills that rise from the meadows of the upper Thames to an escarpment above the Severn Valley and Evesham Vale. The area is defined by the bedrock of Jurassic limestone that creates a type of grassland habitat rare in the UK and that is quarried for the golden-coloured Cotswold stone. The predominantly rural landscape contains stone-built villages, towns, and stately homes and gardens featuring the local stone. Designated as an Area of Outstanding Natural Beauty (AONB) in 1966, the Cotswolds covers making it the largest AONB. It is the third largest protected landscape in England after the Lake District and Yorkshire Dales national parks. Its boundaries are roughly across and long, stretching southwest from just south of Stratford-upon-Avon to just south of Bath near Radstock. It lies across the boundaries of several English counties; mainly Gloucestershire and Oxfordshire, and parts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains And Hills Of England
The mountains and hills of England comprise very different kinds of terrain, from a mountain range which reaches almost high, to several smaller areas of lower mountains, foothills and sea cliffs. Most of the major upland areas have been designated as Areas of Outstanding Natural Beauty (AONB) or national parks. The highest and most extensive areas are in the north and west (including south-west), while the midlands, south-east and east of the country tend to be low-lying. Northern England Lake District The North of England includes the country's highest mountains, in the Lake District of Cumbria. This was one of the first national parks to be established in the United Kingdom, in 1951. The highest peak is Scafell Pike, , and at least three other summits exceed making them Furth Munros. The mountains are chiefly Ordovician slates and volcanic rocks, with some limestone and outcrops of other rock types. The peaks were catalogued and described in Alfred Wainwright's seminal '' ...

Glaciation
A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances. Interglacials, on the other hand, are periods of warmer climate between glacial periods. The Last Glacial Period ended about 15,000 years ago. The Holocene is the current interglacial. A time with no glaciers on Earth is considered a greenhouse climate state. Quaternary Period Within the Quaternary, which started about 2.6 million years before present, there have been a number of glacials and interglacials. At least eight glacial cycles have occurred in the last 740,000 years alone. Penultimate Glacial Period The Penultimate Glacial Period (PGP) is the glacial period that occurred before the Last Glacial Period. It began about 194,000 years ago and ended 135,000 years ago, with the beginning of the Eemian interglacial. Last Glacial Period The last glacial period was the most recent glacial period ...

Jurassic
The Jurassic ( ) is a Geological period, geologic period and System (stratigraphy), 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, 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, 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 Anoxic event, oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar, Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now- extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth b ...
