Dalälven Basin
The Dal River ( sv, Dalälven, Elfdalian: ''Dalövę'') is a river in central Sweden that flows from the north of Dalarna and runs into the sea in northern Uppland; it is commonly considered to be the southern border of Norrland, however only the last part correlates with Limes Norrlandicus (the biological Norrland border). The northern part is split into two rivers: Österdalälven and Västerdalälven. The two connect in Djurås. It is over long — the second longest river in Sweden, and has a hydropower potential of 1420 megawatts, of which 2/3 is utilized. The largest power plant is located at the Trängslet Dam. Dalälven has been significant historically as a raft transport route. Nedre Dalälven River Landscape, Sweden, covers with a mixture of wetlands, rivers, lakes, flood plains and productive forests. It includes Lake Hovran and Färnebofjärden Bay Ramsar site. The region boasts high biodiversity, as the river forms a clear border zone between the northern ...

Avesta (locality)
Avesta () is a locality and the seat of Avesta Municipality in Dalarna County, Sweden, with 11,949 inhabitants in 2015. The name is first found in 1303 as "Aghastadhum". ''Aghe'' is of similar origin as the word å, meaning stream, in this case the Avestafors, a tributary of the river Dalälven. ''Stadhum'' was dative plural of a word of similar origin as stead, or farm. History In the Scandinavian Middle Ages there was a blast furnace at the location. In 1636 the construction of a giant copper mine was initiated near the Avesta fors. The town Avesta received partial privileges in 1641 as a town under the city of Falun, and in 1644 a copper mint was built. However, the privileges were withdrawn in 1688 due to complaints of competition from its neighbour, mainly Falun. Copper coins were continued to be minted until 1831, and the copper works was in function until 1869. Full city rights were regranted in 1919. The designated coat of arms depict the signs for copper and ir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megawatt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units, International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantification (science), quantify the rate of Energy transformation, energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish people, Scottish invention, inventor, mechanical engineer, and chemist who improved the Newcomen steam engine, Newcomen engine with his own Watt steam engine, steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one Newton (unit), newton, the rate at which Work (physics), work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potentia ...

Impact Crater
An impact crater is a circular depression in the surface of a solid astronomical object formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Lunar impact craters range from microscopic craters on lunar rocks returned by the Apollo Program and small, simple, bowl-shaped depressions in the lunar regolith to large, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth. Impact craters are the dominant geographic features on many solid Solar System objects including the Moon, Mercury, Callisto, Ganymede and most small moons and asteroids. On other planets and moons that experience more active surface geological processes, such as Earth, Venus, Europa, Io and Titan, visible impact craters are less common because they become eroded ...

Lake Siljan
Siljan, in Dalarna in central Sweden, is Sweden's seventh largest lake. The cumulative area of Siljan and the adjacent, smaller lakes Orsasjön and Insjön is . Siljan reaches a maximum depth of , and its surface is situated above sea level. The largest town on its shore is Mora. Impact crater The lake is located around the southwestern perimeter of the Siljan Ring (Swedish: ''Siljansringen''), a circular geological formation which was formed 377 million years ago in the Devonian by a major meteorite impact. The original crater, now mostly eroded, is estimated to have been about 52 km (32 mi) in diameter and is the largest known impact crater in Europe (excluding Russia). The Cambrian, Ordovician and Silurian sedimentary rocks deformed by the impact are rich in fossils. Some people suspect that there might be oil in the area, but drilling has been unsuccessful so far. There are large deposits of lead and zinc in the Boda area. Deep drilling project The gov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Göta älv
The Göta älv (; "River of (the) Geats") is a river that drains lake Vänern into the Kattegat, at the city of Gothenburg, on the western coast of Sweden. It was formed at the end of the last glaciation, as an outflow channel from the Baltic Ice Lake to the Atlantic Ocean and nowadays it has the largest drainage basin in Scandinavia. The Göta älv is located in Götaland, with the river itself being a site of early Geatish settlement. Its length is . The Bohus Fortress is located by the river at Kungälv. There the river splits into two, with the northern part being the Nordre älv and the southern part keeping the name Göta älv; the two arms of the river enclose the island of Hisingen.

Baltic Sea
The Baltic Sea is an arm of the Atlantic Ocean that is enclosed by Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, Sweden and the North and Central European Plain.

Biosphere
The biosphere (from Greek βίος ''bíos'' "life" and σφαῖρα ''sphaira'' "sphere"), also known as the ecosphere (from Greek οἶκος ''oîkos'' "environment" and σφαῖρα), is the worldwide sum of all ecosystems. It can also be termed the zone of life on Earth. The biosphere (which is technically a spherical shell) is virtually a closed system with regard to matter, with minimal inputs and outputs. With regard to energy, it is an open system, with photosynthesis capturing solar energy at a rate of around 130 terawatts per year. However it is a self-regulating system close to energetic equilibrium."Biosphere" in ''The Columbia Encyclopedia'', 6th ed. (2004) Columbia University Press.

Northern Europe
The northern region of Europe has several definitions. A restrictive definition may describe Northern Europe as being roughly north of the southern coast of the Baltic Sea, which is about 54th parallel north, 54°N, or may be based on other geographical factors such as climate and ecology. Climate The climate is mainly Oceanic climate (Cfb), Humid continental climate (Dfb), Subarctic climate (Dfc and Dsc) and Tundra (ET). Geography Northern Europe might be defined roughly to include some or all of the following areas: British Isles, Fennoscandia, the peninsula of Jutland, the Baltic region, Baltic plain that lies to the east and the many islands that lie offshore from mainland Northern Europe and the main European continent. In some cases, Greenland is also included, although it is only politically European, comprising part of the Kingdom of Denmark, and not considered to be geographically in Europe. The area is partly mountainous, including the northern volcanic islands ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
