Outer Silver Pit
The Outer Silver Pit is a west-to-east valley in the bed of the North Sea. Its widest part is 125 to 175 km (75 to 105 miles) east of Flamborough Head in England. It is between the Dogger Bank and the ridge dividing the northern from the southern North Sea basins, which runs between Norfolk and Friesland. When the sea level was lower (such as in the Ice Age) it was a lake in Doggerland, and sea-bed-penetrating sonar bathymetry has found its shorelines and courses and estuaries of rivers that ran into it from the high land of the Dogger Bank; it overflowed into a river at its west end.''Mapping Doggerland'', ed. Vincent Gaffney and others, publ. Archaeopres2007, Bed of the Rhine? In the Cromerian Stage, before more recent glaciation had influenced the area, a ridge of high ground, the Weald-Artois Anticline, joined the Upper Cretaceous chalk in Kent, England to that of the Boulonnais at ''Cap Blanc-Nez'' in the Pas de Calais, France.

North Sea
The North Sea lies between Great Britain, Norway, Denmark, Germany, the Netherlands and Belgium. An epeiric sea on the European continental shelf, it connects to the Atlantic Ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than long and wide, covering . It hosts key north European shipping lanes and is a major fishery. The coast is a popular destination for recreation and tourism in bordering countries, and a rich source of energy resources, including wind and wave power. The North Sea has featured prominently in geopolitical and military affairs, particularly in Northern Europe, from the Middle Ages to the modern era. It was also important globally through the power northern Europeans projected worldwide during much of the Middle Ages and into the modern era. The North Sea was the centre of the Vikings' rise. The Hanseatic League, the Dutch Republic, and the British each sought to gain command of the North Sea and access t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cap Blanc-Nez
Cap Blanc-Nez (french: kap blɑ̃ ne, literally "Cape White Nose" in English; from Dutch ''Blankenesse'', white headland) is a cape on the Côte d'Opale, in the Pas-de-Calais ''département'', in northern France, culminating at 134 m. The cliffs of chalk are very similar to the white cliffs of Dover on the other side of the Channel in England. Cap Blanc-Nez does not protrude into the sea like a typical cape but is a high point where a chalk ridge has been truncated by the sea, forming a cliff that is topped by the obelisk of the Dover Patrol Monument, commemorating the Dover Patrol which kept the Channel free from U-boats during World War I. Cap Blanc-Nez was a vital measuring point for the eighteenth-century trigonometric survey linking the Paris Observatory with the Royal Greenwich Observatory. Sightings were made across the English Channel to Dover Castle and Fairlight Windmill on the South Downs. This Anglo-French Survey was led in England by General William Roy. Some ...

Strait 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 ...

Urstrom
The Urstrom is a geologists' name for a great glacial age river of the Polish and north German plain, which drained the combined melt-waters from the northern headwaters of the Alps and the southern part of the Scandinavian ice during the Devensian ice age.K Reicherter, N Froitzheim, M Jarosiński, J Badura, H-J Franzke, M Hansen, C Hübscher, R Müller, P Poprawa, J Reinecker, W Stackebrandt, T Boigt, H von Eynatten & W Zuchiewicz, "Alpine tectonics north of the Alps" in Tom McCann (ed), The Geology of Central Europe: Mesozoic and Cenozoic', vol 2, Geological Society of London, 2008, Chap 19, pp 1233–1234 See also * Urstromtal An ''urstromtal'' (plural: ''Urstromtäler'') is a type of broad glacial valley, for example, in northern Central Europe, that appeared during the ice ages, or individual glacial periods of an ice age, at the edge of the Scandinavian ice sheet and ...

Forebulge
In geology, a forebulge is a flexural bulge in front as a result of a load on the lithosphere, often caused by tectonic interactions and glaciations. An example of forebulge can be seen in the Himalayan foreland basin, a result of the Indian-Eurasian (continent-continent) plate collision, in which the Indian plate subducted and the Eurasian plate created a large load on the lithosphere, leading to the Himalayas and the Ganges foreland basin. Background Forebulge is most commonly found with continent-continent convergent collisions, in which the formation of mountain ranges as the plates collide places a large load on the lithosphere below. The lithosphere flexes in response to the load on the mantle, causing depression and subsidence ( fordeep) followed by the forebulging in the front. The forebulge area is lifted by a height that is 4% of the depression height caused by the load. It takes roughly 10,000 to 20,000 years for forebulge to fully develop when the mantle flexure to ...

Glacial Lake Outburst Flood
A glacial lake outburst flood (GLOF) is a type of outburst flood caused by the failure of a dam containing a glacial lake. An event similar to a GLOF, where a body of water contained by a glacier melts or overflows the glacier, is called a jökulhlaup. The dam can consist of glacier ice or a terminal moraine. Failure can happen due to erosion, a buildup of water pressure, an avalanche of rock or heavy snow, an earthquake or cryoseism, volcanic eruptions under the ice, or massive displacement of water in a glacial lake when a large portion of an adjacent glacier collapses into it. Increasing glacial melting because of climate change, alongside other environmental effects of climate change (i.e permafrost melting) mean that regions with glaciers are likely to see increased flooding risks from GLOFs. This is especially true in the Himalayas where geologies are more active. Definition A glacial lake outburst flood is a type of outburst flood occurring when water dammed by a glac ...

Thames
The River Thames ( ), known alternatively in parts as the River Isis, is a river that flows through southern England including London. At , it is the longest river entirely in England and the 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, Henley-on-Thames and 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 . From Oxford to the Estuary the Thames drops by 55 metres. Running through some of the drier parts of mai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scheldt
The Scheldt (french: Escaut ; nl, Schelde ) is a river that flows through northern France, western Belgium, and the southwestern part of Netherlands, the Netherlands, with its mouth at the North Sea. Its name is derived from an adjective corresponding to Old English ' ("shallow"), English language, Modern English ''shoal'', Low German ''schol'', West Frisian language, West Frisian ''skol'', and Swedish language, Swedish (obsolete) ''skäll'' ("thin"). Course The headwaters of the Scheldt are in Gouy, Aisne, 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 (river), 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 Westersc ... [...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 ...
