Dellen
Dellen is a lake system in the province of Hälsingland, Sweden. It consists of two lakes, ''Northern Dellen'' and ''Southern Dellen'', appreciated among fly-fishermen for their population of brown trout. Southern Dellen has a surface area of 52 km2 and a water volume of 1,226 million m³. Northern Dellen has an area of 82 km2 and a water volume of 1,489 million m³. The two lakes are only separated by a short channel, and it is therefore disputed whether they should be counted as one or two lakes. The two lakes together have a total area of 130 km2, which would be the 18th largest Swedish lake. The vaguely circular lake system was formed by an impact crater 89 million years ago, placing the impact in the Late Cretaceous. The resulting impact crater measures about 19 kilometers in diameter. It has resulted in the area containing the rock Dellenite (a rock intermediate in composition between Rhyolite and Dacite), which has become the provincial rock. Asteroid 770 ...

Sweden Solar System
The Sweden Solar System is the world's largest permanent scale model of the Solar System. The Sun is represented by the Avicii Arena in Stockholm, the largest hemispherical building in the world. The inner planets can also be found in Stockholm but the outer planets are situated northward in other cities along the Baltic Sea. The system was started by Nils Brenning, professor at the Royal Institute of Technology in Stockholm, and Gösta Gahm, professor at the Stockholm University. The model represents the Solar System on the scale of 1:20 million. The system The bodies represented in this model include the Sun, the planets (and some of their moons), dwarf planets and many types of small bodies (comets, asteroids, trans-Neptunians, etc.), as well as some abstract concepts (like the Termination Shock zone). Because of the existence of many small bodies in the real Solar System, the model can always be further increased. The Sun is represented by the Avicii Arena (Globen), Stoc ...

Hälsingland
Hälsingland (), sometimes referred to as Helsingia in English, is a historical province or ''landskap'' in central Sweden. It borders Gästrikland, Dalarna, Härjedalen, Medelpad and the Gulf of Bothnia. It is part of the land of Norrland. Administration The traditional provinces of Sweden serve no administrative or political purpose, but are historical and cultural entities. In the case of Hälsingland the province constitutes the northern part of the ''län'' ('administrative county') Gävleborg County. Minor parts of the province are in Jämtland County and in Västernorrland County. The following municipalities have their seats in Hälsingland: * Bollnäs * Hudiksvall * Ljusdal * Nordanstig * Ovanåker * Söderhamn The six largest settlements are: * Bollnäs * Hudiksvall * Söderhamn * Ljusdal * Edsbyn * Iggesund Heraldry The coat of arms were granted in 1560 in the era of King Gustav Vasa. At that time, Hälsingland was known for its large scale goat breeding, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lakes Of Sweden
The list of lakes of Sweden contains the major lakes in the nation of Sweden. However, Sweden has over 97,500 lakes larger than , so the list is not comprehensive."Lakes, Streams and Rivers" ''Smorgasbord'', 2007, webpage (English language): SverigeTur-lakes. The great number of lakes in southern Sweden could according to Alfred Gabriel Nathorst be indebted to the creation of basins due to the stripping of an irregular mantle of weathered rock by glacier erosion.

Impact Craters Of Sweden
In early 2018 there were eight known impact craters in Sweden. They range in age from 90 mya to 470 mya, and in diameter from 1 km to 52 km. Six of them are exposed, that is they are visible at the surface, in the natural landscape, although their nature and origin might need to be pointed out to the untrained layman. List * Dellen * Granby crater * Hummeln structure * Lockne crater * Målingen Crater * Mien (lake) * Siljan Ring * Tvären See also * Ordovician meteor event The Ordovician meteor event was a dramatic increase in the rate at which L chondrite meteorites fell to Earth during the Middle Ordovician period, about 467.5±0.28 million years ago. This is indicated by abundant fossil L chondrite meteorites in ...H. Haack et al.

Asteroid
An asteroid is a minor planet of the inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere. Of the roughly one million known asteroids the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 AU from the Sun, in the main asteroid belt. Asteroids are generally classified to be of three types: C-type, M-type, and S-type. These were named after and are generally identified with carbonaceous, metallic, and silicaceous compositions, respectively. The size of asteroids varies greatly; the largest, Ceres, is almost across and qualifies as a dwarf planet. The total mass of all the asteroids combined is only 3% that of Earth's Moon. The majority of main belt asteroids follow slightly elliptical, stable orbits, revolving in the same direction as the Earth and taking from three to six years to comple ...

Lakes Of Gävleborg County
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cretaceous Impact Craters
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now-extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth by the ...

Charon (moon)
Charon ( or ), known as (134340) Pluto I, is the largest of the five known natural satellites of the dwarf planet Pluto. It has a mean radius of . Charon is the sixth-largest known trans-Neptunian object after Pluto, Eris, Haumea, Makemake and Gonggong. It was discovered in 1978 at the United States Naval Observatory in Washington, D.C., using photographic plates taken at the United States Naval Observatory Flagstaff Station (NOFS). With half the diameter and one eighth the mass of Pluto, Charon is a very large moon in comparison to its parent body. Its gravitational influence is such that the barycenter of the Plutonian system lies outside Pluto, and the two bodies are tidally locked to each other. The reddish-brown cap of the north pole of Charon is composed of tholins, organic macromolecules that may be essential ingredients of life. These tholins were produced from methane, nitrogen and related gases which may have been released by cryovolcanic eruptions on the moon, o ...

Pluto
Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of trans-Neptunian object, bodies beyond the orbit of Neptune. It is the ninth-largest and tenth-most-massive known object to directly orbit the Sun. It is the largest known trans-Neptunian object by volume, by a small margin, but is slightly less massive than Eris (dwarf planet), Eris. Like other Kuiper belt objects, Pluto is made primarily of ice and rock and is much smaller than the inner planets. Compared to Moon, Earth's moon, Pluto has only one sixth its mass and one third its volume. Pluto has a moderately orbital eccentricity, eccentric and inclined orbit, ranging from from the Sun. Light from the Sun takes 5.5 hours to reach Pluto at its average distance (). Pluto's eccentric orbit periodically brings it closer to the Sun than Neptune, but a stable orbital resonance prevents them from colliding. Pluto has moons of Pluto, five known moons: Charon (moon), Charon, the larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Provinces Of Sweden
The provinces of Sweden ( sv, Sveriges landskap) are historical, geographical and cultural regions. Sweden has 25 provinces; they have no administrative function (except for in some cases as sport districts), but remain historical legacies and a means of cultural identification as pertains, for example, to dialects and folklore. Several of them were subdivisions of Sweden until 1634, when they were replaced by the counties of Sweden (''län''). Some were conquered later on from Denmark–Norway. Others, like the provinces of Finland, were lost. Lapland is the only province acquired through colonization. In some cases, the administrative counties correspond almost exactly to the provinces, as is Blekinge to Blekinge County and Gotland, which is a province, county and a municipality. While not exactly corresponding with the province, Härjedalen Municipality is beside Gotland the only municipality named after a province. In other cases, the county borders do not correspond with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
