Salisbury Plain Training Area
Salisbury Plain is a chalk plateau in the south western part of central southern England covering . It is part of a system of chalk downlands throughout eastern and southern England formed by the rocks of the Chalk Group and largely lies within the county of Wiltshire, but stretches into Hampshire. The plain is famous for its rich archaeology, including Stonehenge, one of England's best known landmarks. Large areas are given over to military training and thus the sparsely populated plain is the biggest remaining area of calcareous grassland in northwest Europe. Additionally the plain has arable land, and a few small areas of beech trees and coniferous woodland. Its highest point is Easton Hill. Physical geography The boundaries of Salisbury Plain have never been truly defined, and there is some difference of opinion as to its exact area. The river valleys surrounding it, and other downs and plains beyond them loosely define its boundaries. To the north the scarp of the d ...

Summer Solstice Sunrise Over Stonehenge 2005
Summer is the hottest of the four temperate seasons, occurring after spring and before autumn. At or centred on the summer solstice, the earliest sunrise and latest sunset occurs, daylight hours are longest and dark hours are shortest, with day length decreasing as the season progresses after the solstice. The date of the beginning of summer varies according to climate, tradition, and culture. When it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere, and vice versa. Timing From an astronomical view, the equinoxes and solstices would be the middle of the respective seasons, but sometimes astronomical summer is defined as starting at the solstice, the time of maximal insolation, often identified with the 21st day of June or December. By solar reckoning, summer instead starts on May Day and the summer solstice is Midsummer. A variable seasonal lag means that the meteorological centre of the season, which is based on average temperature patterns ...

Vale Of Pewsey
The Vale of Pewsey or Pewsey Vale is an area of Wiltshire, England to the east of Devizes and south of Marlborough, centred on the village of Pewsey. Geography The vale is an extent of lower lying ground separating the chalk downs of Salisbury Plain to the south from the Marlborough Downs to the north. It is around long and around wide. At the western end is the town of Devizes. Larger settlements in the vale include Pewsey and Burbage with many smaller villages, the larger ones including Bishops Cannings, Etchilhampton, Urchfont, Chirton, Alton Priors, Woodborough, Milton Lilbourne, Easton Royal and Wootton Rivers. Although not itself part of the downs, the vale is included as part of the North Wessex Downs AONB (Area of Outstanding Natural Beauty). The vale is a major east–west feature opening to the west towards the Bristol Channel, but is drained by the headwaters of the Salisbury Avon, rather than the westward-flowing Bristol Avon.

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] |
Clay
Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4). Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide. Clay is the oldest known ceramic material. Prehistoric humans discovered the useful properties of clay and used it for making pottery. Some of the earliest pottery shards have been dated to around 14,000 BC, and clay tablets were the first known writing medium. Clay is used in many modern industrial processes, such as paper making, cement production, and chemical filtering. Between one-half and two-thirds of the world's population live or work in buildings made with clay, often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cranborne Chase
Cranborne Chase () is an area of central southern England, straddling the counties Dorset, Hampshire and Wiltshire. It is part of the Cranborne Chase and West Wiltshire Downs Area of Outstanding Natural Beauty (AONB). The area is dominated by, and often considered to be synonymous with, a chalk downland plateau. Part of the English Chalk Formation, it is adjacent to Salisbury Plain and the West Wiltshire Downs in the north, and the Dorset Downs to the south west. The highest point is Win Green Down, in Wiltshire, at . Historically a medieval hunting forest, the area is also noted for its Neolithic and Bronze age archaeology and its rural agricultural character. Definitions As an informally defined region, the boundaries of Cranborne Chase vary depending on usage. When defined as the chalk plateau, it is clearly bounded by escarpments which face the valleys of the Blackmore Vale to the west, the Vale of Wardour to the north, and the Hampshire Avon to the east.

Berkshire Downs
The Berkshire Downs are a range of chalk downland hills in South east England split between the counties of Berkshire and Oxfordshire. They are part of the North Wessex Downs Area of Outstanding Natural Beauty. The western parts of the downs are also known as the Lambourn Downs. Geography The Berkshire Downs run east–west, with their scarp slope facing north into the Vale of White Horse and their dip slope bounded by the course of the River Kennet. Geologically they are continuous with the Marlborough Downs to the west and the Chilterns to the east. In the east they are divided from the Chilterns by Goring Gap on the River Thames. In the west their boundary is generally taken to be the border between Berkshire and Wiltshire, although the downs in Wiltshire between the Berkshire border and the valley of the River Og are sometimes considered to be part of the Berkshire Downs.

River Avon, Hampshire
The River Avon () is in the south of England, rising in Wiltshire, flowing through that county's city of Salisbury and then west Hampshire, before reaching the English Channel through Christchurch Harbour in the Bournemouth, Christchurch and Poole conurbation of Dorset. It is sometimes known as the Salisbury Avon or the Hampshire Avon to distinguish it from namesakes across Great Britain. It is one of the rivers in Britain in which the phenomenon of anchor ice has been observed. The Avon is thought to contain more species of fish than any other river in Britain. Long-farmed pastures and planted, arable fields line much of the valley; an indication of the wealth these brought to landowners is in ten large listed houses with statutorily recognised and protected parks. Many prehistoric sites and broader "landscapes" are found on either side of the river, the largest being the World Heritage Site zone of Stonehenge, Avebury and Associated Sites, followed by the Old Sarum knoll for ...
