Flechtingen Hills
The Flechtingen Hills () are a wooded, hilly Highland (geography), upland area up to 179 m high in the northwestern part of the German state of Saxony-Anhalt, named after the town of Flechtingen. Location The Flechtingen Hills are bordered by the River Aller (Germany), Aller to the west, the Spetze, a right-hand tributary of the Aller, to the north, the valley of the Ohre to the northeast, through which the Mittelland Canal also runs, and by the Beber (Ohre), Beber, a tributary of the Ohre, to the south. One of the highest elevations in the Flechtingen Hills is the ''Butterberg'' near Ivenrode at . Geology Unlike the surrounding region, geologically old rocks reach the surface of the Flechtingen Hills. It thus forms the northernmost region of bedrock in Germany, because North Germany is almost completely covered by unconsolidated rocks of the Quaternary period. The ridge is mostly composed of volcanic rock and sedimentary rocks of the Carboniferous and Permian periods. In pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saxony-Anhalt
Saxony-Anhalt ( ; ) is a States of Germany, state of Germany, bordering the states of Brandenburg, Saxony, Thuringia and Lower Saxony. It covers an area of and has a population of 2.17 million inhabitants, making it the List of German states by area, 8th-largest state in Germany by area and the List of German states by population, 11th-largest by population. Its capital and most populous city is Magdeburg. The state of Saxony-Anhalt was formed in July 1945 after World War II, when the Soviet Military Administration in Germany, Soviet army administration in Allied-occupied Germany formed it from the former Free State of Prussia, Prussian Province of Saxony and the Free State of Anhalt. Saxony-Anhalt became part of the East Germany, German Democratic Republic in 1949, but was dissolved in 1952 during Administrative divisions of East Germany, administrative reforms and its territory was divided into the districts of Halle (Bezirk), Halle and Magdeburg (Bezirk), Magdeburg.

Sedimentary Rock
Sedimentary rocks are types of rock (geology), rock formed by the cementation (geology), cementation of sediments—i.e. particles made of minerals (geological detritus) or organic matter (biological detritus)—that have been accumulated or deposited at Earth's surface. Sedimentation is any process that causes these particles to settle in place. Geological detritus originates from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or Mass wasting, mass movement, which are called agents of denudation. Biological detritus is formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies (marine snow). Sedimentation may also occur when dissolved minerals precipitate from aqueous solution, water solution. The sedimentary rock cover of ...

Elbe
The Elbe ( ; ; or ''Elv''; Upper Sorbian, Upper and , ) is one of the major rivers of Central Europe. It rises in the Giant Mountains of the northern Czech Republic before traversing much of Bohemia (western half of the Czech Republic), then Germany and flowing into the North Sea at Cuxhaven, northwest of Hamburg. Its total length is . The Elbe's major Tributary, tributaries include the rivers Vltava, Ohře, Saale, Havel, Mulde, and Schwarze Elster. The Elbe river basin, comprising the Elbe and its tributaries, has a catchment area of , the twelfth largest in Europe. The basin spans four countries; however, it lies almost entirely just in two of them, Germany (65.5%) and the Czech Republic (33.7%, covering about two thirds of the nation's territory). On its southeastern edges, the Elbe river basin also comprises small parts of Austria (0.6%) and Poland (0.2%). The Elbe catchment area is inhabited by 24.4 million people; its biggest cities are Berlin, Hamburg, Prague, Dresden a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magdeburg Domfelsen
The Domfelsen is a rock formation near Magdeburg Cathedral, part of which juts out into the River Elbe in Germany. The name means "Cathedral Rocks" Geology The Domfelsen consists mainly of sandstone with a small proportion of siltstone. The rock is part of the rotliegendes formation and thus dates to the Lower Permian period. This outcrop of bedrock may be viewed as a continuation of the Flechtingen Hills that, in the urban area of Magdeburg, is mostly covered by a thin layer of Quaternary depositions. Significance The rocks are of particular significance for river navigation on the Elbe and also for the river's ecosystem. The rocks, which are clearly visible on the west bank below the cathedral when water levels are low, affect local current conditions. Even during high water, ships can only pass down the river by sailing close to the eastern bank. Commercial shipping is not allowed to cross at this point; traffic is regulated remotely by a light system. The speed of the c ...

Roßlau (Elbe)
Rosslau (in German orthography: Roßlau) was until 30 June 2007 a town in Saxony-Anhalt, Germany, belonging to the district Anhalt-Zerbst. After a fusion with the town of Dessau it became eponym of the newly founded town of Dessau-Roßlau and a quarter of it. Rosslau is situated on the right bank of the Elbe, here crossed by two railway bridges, 3 mi. by rail N. of Dessau and 35 mi. S.E. of Magdeburg. It has a ducal residence, an old castle, a handsome parish church, and manufactures of machinery, paper, sealing-wax, wire goods, sugar, bricks and chemicals. Rosslau became a town in 1603. Town merger On 1 July 2007 the town ''Rosslau (Elbe)'' was consolidated with the town ''Dessau''. Together they are named Dessau-Roßlau.

Magdeburg
Magdeburg (; ) is the Capital city, capital of the Germany, German States of Germany, state Saxony-Anhalt. The city is on the Elbe river. Otto I, Holy Roman Emperor, Otto I, the first Holy Roman Emperor and founder of the Archbishopric of Magdeburg, was buried in the city's Magdeburg Cathedral, cathedral after his death. Magdeburg's version of German town law, known as Magdeburg rights, spread throughout Central Europe, Central and Eastern Europe. In the Late Middle Ages, Magdeburg was one of the largest and most prosperous German cities and a notable member of the Hanseatic League. One of the most notable people from the city was Otto von Guericke, famous for his experiments with the Magdeburg hemispheres. Magdeburg has experienced three major devastations in its history. In 1207 the first catastrophe struck the city, with a fire burning down large parts of the city, including the Magdeburg Cathedral#Previous building, Ottonian cathedral.

Drömling
Drömling is a sparsely populated depression on the border of Lower Saxony and Saxony-Anhalt in Germany with an area of about . The larger part belonging to Saxony-Anhalt in the east has been a nature park since 1990. The former swampland was transformed by drainage from a natural into a cultural landscape in the 18th century under the direction of Frederick the Great of Prussia. Today the depression, with its waterways, the Mittelland Canal and the rivers Aller and Ohre is a refuge for rare or endangered animal and plant species. Most of the area is now made up of nature reserves and protected areas. Nearby towns include Oebisfelde and Wolfsburg. Location Drömling lies in a flat hollow measuring about 15 to 20 kilometres across and surrounding by a 60-metre contour. It is a wider section of the Breslau-Magdeburg-Bremen glacial valley.

Quarries
A quarry is a type of open-pit mine in which dimension stone, rock, construction aggregate, riprap, sand, gravel, or slate is excavated from the ground. The operation of quarries is regulated in some jurisdictions to manage their safety risks and reduce their environmental impact. The word ''quarry'' can also include the underground quarrying for stone, such as Bath stone. History For thousands of years, only hand tools had been used in quarries. In the eighteenth century, the use of drilling and blasting operations was mastered. Types of rock Types of rock extracted from quarries include: *Chalk *China clay *Cinder *Clay *Coal *Construction aggregate (sand and gravel) *Coquina *Diabase *Gabbro *Granite *Gritstone *Gypsum *Limestone *Marble *Ores *Phosphate rock *Quartz *Sandstone *Slate *Travertine Methods of quarrying The method of removal of stones from their natural bed by using different operations is called quarrying.

Permian
The Permian ( ) is a geologic period and System (stratigraphy), stratigraphic system which spans 47 million years, from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.902 Mya. It is the sixth and last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the Perm Governorate, region of Perm in Russia. The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the Sauropsida, sauropsids (reptiles). The world at the time was dominated by the supercontinent Pangaea, which had formed due to the collision of Euramerica and Gondwana during the Carboniferous. Pangaea was surrounded by the superocean Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. Amniotes, which could better cope with these ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carboniferous
The Carboniferous ( ) is a Geologic time scale, geologic period and System (stratigraphy), system of the Paleozoic era (geology), era that spans 60 million years, from the end of the Devonian Period Ma (million years ago) to the beginning of the Permian Period, Ma. It is the fifth and penultimate period of the Paleozoic era and the fifth period of the Phanerozoic eon (geology), eon. In North America, the Carboniferous is often treated as two separate geological periods, the earlier Mississippian (geology), Mississippian and the later Pennsylvanian (geology), Pennsylvanian. The name ''Carboniferous'' means "coal-bearing", from the Latin ("coal") and ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern "system" names, it was coined by geologists William Conybeare (geologist), William Conybeare and William Phillips (geologist), William Phillips in 1822, based on a study of the British rock succession. Carboniferous is the per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic
A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth's plate boundaries are underwater, most volcanoes are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes resulting from divergent tectonic activity are usually non-explosive whereas those resulting from convergent tectonic activity cause violent eruptions."Mid-ocean ridge tectonics, volcanism and geomorphology." Geology 26, no. 455 (2001): 458. https://macdonald.faculty.geol.ucsb.edu/papers/Macdonald%20Mid-Ocean%20Ridge%20Tectonics.pdf Volcanoes can also form where there is stretching a ...

Highland (geography)
Highlands or uplands are areas of high elevation such as a mountainous region, elevated mountainous plateau or high hills. Generally, ''upland'' refers to a range of hills, typically from up to , while ''highland'' is usually reserved for ranges of low mountains. However, the two terms are interchangeable and also include regions that are transitional between hilly and mountainous terrain. Highlands internationally Probably the best-known area officially or unofficially referred to as ''highlands'' in the Anglosphere is the Scottish Highlands in northern Scotland, the mountainous region north and west of the Highland Boundary Fault. The Highland council area is a local government area in the Scottish Highlands and Britain's largest local government area. Other highland or upland areas reaching 400 m or higher in the United Kingdom include the Southern Uplands in Scotland, the Pennines, North York Moors, Dartmoor and Exmoor in England, and the Cambrian Mountains in Wales.
