Erms
The Erms () is a river of the karstified Swabian Alb range in Baden-Württemberg, Germany. It flows into the Neckar in Neckartenzlingen. On its way from the Karst spring to the next large municipality Bad Urach, a former Erms sedimented, especially during floods, no less than eight valley cataracts, where chemically precipitated travertine repeatedly drops . Geography The Ermstal valley is one of the largest valley systems that have cut into the layer of the Swabian Alb from the northwest. The nearby large waters of the river system of the Rhine lie much deeper than the Danube on the south-eastern side of the Alb, so that regressive erosion of the Rhenish waters is gradually shifting back the European watershed at the expense of the Danube basin. Due to the Neckar river, which runs here particularly close to the Alb's eaves, and the great difference in altitude between them, the Erms possessed sufficient erosive power to form one of the most striking valleys of the Alb's eav ...

Karst
Karst () is a topography formed from the dissolution of soluble carbonate rocks such as limestone and Dolomite (rock), dolomite. It is characterized by features like poljes above and drainage systems with sinkholes and caves underground. There is some evidence that karst may occur in more weathering-resistant rocks such as quartzite given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. In regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's Oil and gas reserves and resource quantification, hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems.

Limestone
Limestone is a type of carbonate rock, carbonate sedimentary rock which is the main source of the material Lime (material), lime. It is composed mostly of the minerals calcite and aragonite, which are different Polymorphism (materials science), crystal forms of calcium carbonate . Limestone forms when these minerals Precipitation (chemistry), 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 (rock), dolomite, a closely related rock, which contains a high percentage of the mineral Dolomite (mine ...

Neckar
The Neckar () is a river in Germany, mainly flowing through the southwestern States of Germany, state of Baden-Württemberg, with a short section through Hesse. The Neckar is a major right tributary of the Rhine. Rising in the Schwarzwald-Baar-Kreis near Villingen-Schwenningen, Schwenningen in the ''Schwenninger Moos'' conservation area at a height of above sea level, it passes through Rottweil, Rottenburg am Neckar, Kilchberg (Tübingen), Kilchberg, Tübingen, Wernau, Nürtingen, Plochingen, Esslingen am Neckar, Esslingen, Stuttgart, Ludwigsburg, Marbach am Neckar, Marbach, Heilbronn and Heidelberg, before discharging on average of water into the Rhine at Mannheim, at above sea level, making the Neckar its 4th largest tributary, and the 10th largest river in Germany. Since 1968, the Neckar has been navigable for cargo ships via 27 locks for about upstream from Mannheim to the river port of Plochingen, at the confluence with the Fils (river), Fils.

States Of Germany
The Federal Republic of Germany is a federation and consists of sixteen partly sovereign ''states''. Of the sixteen states, thirteen are so-called area-states ('Flächenländer'); in these, below the level of the state government, there is a division into local authorities (counties and county-level cities) that have their own administration. Two states, Berlin and Hamburg, are city-states, in which there is no separation between state government and local administration. The state of Bremen (state), Bremen is a special case: the state consists of the cities of Bremen (city), Bremen, for which the state government also serves as the municipal administration, and Bremerhaven, which has its own local administration separate from the state government. It is therefore a mixture of a city-state and an area-state. Three states, Bavaria, Saxony, and Thuringia, use the appellation ("free state"); this title is merely stylistic and carries no legal or political significance (similar t ...

Rhine
The Rhine ( ) is one of the List of rivers of Europe, major rivers in Europe. The river begins in the Swiss canton of Graubünden in the southeastern Swiss Alps. It forms part of the Swiss-Liechtenstein border, then part of the Austria–Switzerland border, Swiss-Austrian border. From Lake Constance downstream, it forms part of the Germany-Switzerland border, Swiss-German border. After that the Rhine defines much of the Franco-German border. It then flows in a mostly northerly direction through the German Rhineland. Finally, the Rhine turns to flow predominantly west to enter the Netherlands, eventually emptying into the North Sea. It drains an area of 185,000 km2. Its name derives from the Gaulish language, Gaulish ''Rēnos''. There are two States of Germany, German states named after the river, North Rhine-Westphalia and Rhineland-Palatinate, in addition to several districts of Germany, districts (e.g. Rhein-Sieg-Kreis, Rhein-Sieg).

Stratum
In geology and related fields, a stratum (: strata) is a layer of rock or sediment characterized by certain lithologic properties or attributes that distinguish it from adjacent layers from which it is separated by visible surfaces known as either '' bedding surfaces'' or ''bedding planes''.Salvador, A. ed., 1994. ''International stratigraphic guide: a guide to stratigraphic classification, terminology, and procedure. 2nd ed.'' Boulder, Colorado, The Geological Society of America, Inc., 215 pp. . Prior to the publication of the International Stratigraphic Guide, older publications have defined a stratum as being either equivalent to a single bed or composed of a number of beds; as a layer greater than 1 cm in thickness and constituting a part of a bed; or a general term that includes both ''bed'' and '' lamina''.Neuendorf, K.K.E., Mehl, Jr., J.P., and Jackson, J.A. , eds., 2005.

Precipitation (chemistry)
In an aqueous solution, precipitation is the "sedimentation of a solid material (a precipitate) from a liquid solution". The solid formed is called the precipitate. In case of an inorganic chemical reaction leading to precipitation, the chemical reagent causing the solid to form is called the precipitant. The clear liquid remaining above the precipitated or the centrifuged solid phase is also called the supernate or supernatant. The notion of precipitation can also be extended to other domains of chemistry (organic chemistry and biochemistry) and even be applied to the solid phases (e.g. metallurgy and alloys) when solid impurities segregation (materials science), segregate from a solid phase. Supersaturation The precipitation of a compound may occur when its concentration exceeds its solubility. This can be due to temperature changes, solvent evaporation, or by mixing solvents. Precipitation occurs more rapidly from a strongly supersaturated solution. The formation of a pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swabian Alb
The Swabian Jura ( , more rarely ), sometimes also named Swabian Alps in English, is a mountain range in Baden-Württemberg, Germany, extending from southwest to northeast and in width. It is named after the region of Swabia. It is part of the Table Jura (). The Swabian Jura occupies the region bounded by the Danube in the southeast and the upper Neckar in the northwest. In the southwest it rises to the higher mountains of the Black Forest. The highest mountain in the region is the Lemberg (). The area's profile resembles a high plateau, which slowly falls away to the southeast. The northwestern edge is a steep escarpment (called the Albtrauf or Albanstieg, rising up , covered with forests), while the top is flat or gently rolling. In economic and cultural terms, the Swabian Jura includes regions just around the mountain range. It is a popular recreation area. The whole ''Schwäbische Alb'' area is a UNESCO global geopark covering 6,688 km2 (2582 sq mi.); it was designate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Water Power
Hydropower (from Ancient Greek -, "water"), also known as water power or water energy, is the use of falling or fast-running water to produce electricity or to power machines. This is achieved by converting the gravitational potential or kinetic energy of a water source to produce power. Hydropower is a method of sustainable energy production. Hydropower is now used principally for hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity. Hydropower is an attractive alternative to fossil fuels as it does not directly produce carbon dioxide or other atmospheric pollutants and it provides a relatively consistent source of power. Nonetheless, it has economic, sociological, and environmental downsides and requires a sufficiently energetic source of water, such as a river or elevated lake. International institutions such as the World Bank view hydropower as a low-carbon means for economic development. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
