Proto-Thames
The Ancestral Thames is the geologically ancient precursor to the present day River Thames. Relationships with other rivers During the Early and Middle Pleistocene, central and southern Britain had two main rivers of more than : the Bytham and the Ancestral Thames. For most of the Early Pleistocene the Ancestral Thames was the main river with, at its maximum extent, a catchment area that extended into Wales alongside the Chiltern Hills, through southern East Anglia and finally into Doggerland (now the North Sea), where it joined the Ancestral Rhine. In the early Ice Age the Thames took a line similar to the present-day River Thame, through parts of Bedfordshire, Hertfordshire and north-west Essex, then took a course resembling that of the River Waveney along the Suffolk/Norfolk border. Initially the more northerly Bytham River was a tributary of the Thames but as the climate warmed it progressively extended its catchment. During the Anglian Stage the Bytham river more or less ...

River Thames
The River Thames ( ), known alternatively in parts as the The Isis, River Isis, is a river that flows through southern England including London. At , it is the longest river entirely in England and the Longest rivers of the United Kingdom, second-longest in the United Kingdom, after the River Severn. The river rises at Thames Head in Gloucestershire, and flows into the North Sea near Tilbury, Essex and Gravesend, Kent, via the Thames Estuary. From the west it flows through Oxford (where it is sometimes called the Isis), Reading, Berkshire, Reading, Henley-on-Thames and Windsor, Berkshire, Windsor. The Thames also drains the whole of Greater London. In August 2022, the source of the river moved five miles to beyond Somerford Keynes due to the heatwave in July 2022. The lower reaches of the river are called the Tideway, derived from its long tidal reach up to Teddington Lock. Its tidal section includes most of its London stretch and has a rise and fall of .

Bytham River
The Bytham River is said to have been one of the great Pleistocene rivers of central and eastern England until it was destroyed by the advancing ice sheets of the Anglian Glaciation around 450,000 years ago. The river is named after Castle Bytham in Lincolnshire, where the watercourse is said to have crossed the Lincolnshire limestone hills in a valley now buried by Anglian till. West of that location, its catchment area included much of Warwickshire, Leicestershire and Derbyshire. East of that location, the Bytham flowed across what is now the Fen Basin to Shouldham, then southward to Mildenhall, then eastward across East Anglia. It met the Proto-Thames in a delta near what is now the Norfolk/Suffolk border and flowed into the North Sea. Britain was then joined to the Continent by a land bridge and the Bytham joined the North Sea somewhere beyond the northern end of that land bridge. Chris Stringer writes: "As the Bytham River slowed past Warren Hill n Norfolktowards its delt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anglian Stage
The Anglian Stage is the name used in the British Isles for a middle Pleistocene glaciation. It precedes the Hoxnian Stage and follows the Cromerian Stage in the British Isles. The Anglian Stage is correlated to Marine Isotope Stage 12 (MIS 12), which started about 478,000 years ago and ended about 424,000 years ago. Lisiecki, L.E. (2005Ages of MIS boundaries.

Kesgrave Sands And Gravels
Kesgrave is a town in the English county of Suffolk on the eastern edge of Ipswich. Kesgrave forms part of the wider Ipswich Built-up area. History The area was recorded as ''Gressgrava'' in the Domesday Book, by the late 15th century its name had become Kesgrave. Kesgrave remained a small agricultural settlement with just a church, inn and a few farmsteads for over 700 years. In 1921 the population was only 103 housed in 20 dwellings. Since then great changes have taken place. By 1988 Kesgrave covered an area of more than . Kesgrave parish council officially adopted the title of a town in January 2000. Schools Kesgrave High School is a large 11-18 comprehensive co-educational school with nearly 2000 pupils. A study for Sustrans noted that 61% of the pupils cycled to the school. This is largely due to the installation of a large cycle lane through the local housing development and along the main road. The school actively encourages walking or cycling and provides bicycle st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic Rocks
Volcanic rock (often shortened to volcanics in scientific contexts) is a Rock (geology), rock formed from lava erupted from a volcano. In other words, it differs from other igneous rock by being of Volcano, volcanic origin. Like all rock types, the concept of volcanic rock is artificial, and in nature volcanic rocks grade into Subvolcanic rock, hypabyssal and metamorphic rocks and constitute an important element of some sediments and sedimentary rocks. For these reasons, in geology, volcanics and shallow hypabyssal rocks are not always treated as distinct. In the context of Precambrian shield (geology), shield geology, the term "volcanic" is often applied to what are strictly metavolcanic rocks. Volcanic rocks and sediment that form from magma erupted into the air are called "volcaniclastics," and these are technically sedimentary rocks. Volcanic rocks are among the most common rock types on Earth's surface, particularly in the oceans. On land, they are very common at plate bound ...

Straits Of Dover
The Strait of Dover or Dover Strait (french: Pas de Calais - ''Strait of Calais''), is the strait at the narrowest part of the English Channel, marking the boundary between the Channel and the North Sea, separating Great Britain from continental Europe. The shortest distance across the strait, at approximately 20 miles (32 kilometres), is from the South Foreland, northeast of Dover in the English county of Kent, to Cap Gris Nez, a cape near to Calais in the French département of Pas-de-Calais. Between these points lies the most popular route for cross-channel swimmers. The entire strait is within the territorial waters of France and the United Kingdom, but a right of transit passage under the United Nations Convention on the Law of the Sea allows vessels of other nations to move freely through the strait. On a clear day, it is possible to see the opposite coastline of England from France and vice versa with the naked eye, with the most famous and obvious sight being the White ...

Yorkshire
Yorkshire ( ; abbreviated Yorks), formally known as the County of York, is a Historic counties of England, historic county in northern England and by far the largest in the United Kingdom. Because of its large area in comparison with other English counties, functions have been undertaken over time by its subdivisions, which have also been subject to History of local government in Yorkshire, periodic reform. Throughout these changes, Yorkshire has continued to be recognised as a geographic territory and cultural region. The name is familiar and well understood across the United Kingdom and is in common use in the media and the Yorkshire Regiment, military, and also features in the titles of current areas of civil administration such as North Yorkshire, South Yorkshire, West Yorkshire and the East Riding of Yorkshire. Within the borders of the historic county of Yorkshire are large stretches of countryside, including the Yorkshire Dales, North York Moors and Peak District nationa ...

Scheldt River
The Scheldt (french: Escaut ; nl, Schelde ) is a river that flows through northern France, western Belgium, and the southwestern part of the Netherlands, with its mouth at the North Sea. Its name is derived from an adjective corresponding to Old English ' ("shallow"), Modern English ''shoal'', Low German ''schol'', West Frisian ''skol'', and Swedish (obsolete) ''skäll'' ("thin"). Course The headwaters of the Scheldt are in Gouy, in the Aisne department of northern France. It flows north through Cambrai and Valenciennes, and enters Belgium near Tournai. Ghent developed at the confluence of the Lys, one of its main tributaries, and the Scheldt, which then turns east. Near Antwerp, the largest city on its banks, the Scheldt flows west into the Netherlands toward the North Sea. Originally there were two branches from that point: the Oosterschelde (Eastern Scheldt); and the Westerschelde (Western Scheldt). In the 19th century, however, the Dutch built a dyke that cuts the r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meuse River
The Meuse ( , , , ; wa, Moûze ) or Maas ( , ; li, Maos or ) is a major European river, rising in France and flowing through Belgium and the Netherlands before draining into the North Sea from the Rhine–Meuse–Scheldt delta. It has a total length of . History From 1301 the upper Meuse roughly marked the western border of the Holy Roman Empire with the Kingdom of France, after Count Henry III of Bar had to receive the western part of the County of Bar (''Barrois mouvant'') as a French fief from the hands of King Philip IV. In 1408, a Burgundian army led by John the Fearless went to the aid of John III against the citizens of Liège, who were in open revolt. After the battle which saw the men from Liège defeated, John ordered the drowning in the Meuse of suspicious burghers and noblemen in Liège. The border remained stable until the annexation of the Three Bishoprics Metz, Toul and Verdun by King Henry II in 1552 and the occupation of the Duchy of Lorraine by the ...

Palaeogeographer
Palaeogeography (or paleogeography) is the study of historical geography, generally physical landscapes. Palaeogeography can also include the study of human or cultural environments. When the focus is specifically on landforms, the term paleogeomorphology is sometimes used instead. Paleomagnetism, paleobiogeography, and tectonic history are among its main tools. Palaeogeography yields information that is crucial to scientific understanding in a variety of contexts. For example, palaeogeographical analysis of sedimentary basins plays a key role in the field of petroleum geology, because ancient geomorphological environments of the Earth's surface are preserved in the stratigraphic record. Palaeogeographers also study the sedimentary environment associated with fossils for clues to the evolutionary development of extinct species. Palaeogeography is furthermore crucial to the understanding of palaeoclimatology, due to the impact of the positions of continents and oceans on influe ...
