Hurumlandet
Hurumlandet is a peninsula in AKershus county, Norway. It is situated west of the Oslofjord and east of the Drammensfjord. It comprises the southern parts of the municipality Asker. It is connected to Follo through the subsea Oslofjord Tunnel. Before 1990, Hurumlandet was the planned location for the new Oslo Airport. Ultimately, the airport was allocated to Gardermoen. History Since the Middle Ages, Hurumlandet was a strategic headland at the entrance to the country's capital. Militarily the peninsula has been of great importance and fortifications date since the Middle Ages. West at the Drammenfjord are fortifications from the 1890s. Geography The bedrock is very varied with the remains of an ancient volcano in the central and Ersvika and a lot of red granite in key areas. Hurum municipality consists mostly of granite deposits in the west and center parties, with deposits of shale and sandstone in a belt in the south and east. In the south there are also some limeston ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oslofjord Tunnel
The Oslofjord Tunnel () is a subsea road tunnel which traverses the Oslofjord, connecting Hurum and Frogn in Norway. Carrying three lanes, the long tunnel reaches a depth of below mean sea level. The tunnel has a maximum gradient of seven percent. It acts as a link connecting eastern and western Akershus, Akershus county, supplementing the Moss–Horten Ferry which runs further south. The tunnel is since 2018 a part of European route E134, until 2018 it was part of Norwegian National Road 23, National Road 23. The crossing was originally served by the Drøbak–Storsand Ferry, which commenced in 1939. Plans for a fixed link were launched in 1963, originally based on two bridges which would connect to Håøya, Akershus, Håøya. Plans resurfaced in the early 1980s with the advent of subsea tunneling technology and the Oslo Airport location controversy, which proposed airports in Hurum, Ås, Akershus, Ås and Hobøl. Even though Oslo Airport, Gardermoen, Gardermoen was ultimate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drammensfjorden
Drammensfjord () is a fjord in along the border of Akershus and Buskerud counties in Norway that connects to Ytre Oslofjord on the west side. It stretches about to the north and northeast. The Drammenselva river discharges into the head of the fjord. The fjord shares its name with the city of Drammen, which is located at the head of the fjord. Drammen Municipality is located on its west and north sides. The land on the east side of the fjord is called ''Hurumhalvøya'' or the Hurum peninsula and this is located in Asker Municipality. The peninsula lies between the Drammensfjord and the Oslofjord. The fjord narrows to a strait at Svelvik on the west side and Verket in Asker on the east side. The strait is crossed by an automobile ferry. This narrowing, some broad and deep, combined with the large freshwater inflow from the river Drammenselva (one of Norway's largest rivers) and from the river Lierelva, results in the water north of the strait being brackish. On the su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Hurum
Hurum was a municipality in Buskerud county, Norway. As of 1 January 2020 Hurum has merged with the municipalities of Røyken and Asker to form the new Asker Municipality located in the newly formed Viken county. The administrative centre of the municipality is the village Sætre. The municipality of Hurum was established on 1 January 1838 (see formannskapsdistrikt). The small village of Holmsbu was granted town status in 1847, but it did not become a municipality of its own. It lost its town status on 1 January 1964. Hurum was once suggested as the location for the new national airport of Norway. The plan was, however, abandoned, due to fears of too much fog in Hurum, and the main airport is now situated at Gardermoen in Akershus. Etymology Name The Old Norse form of the name was ''Húðrimar''. The meaning of the first element ''(Húð)'' is unknown and the last element is the plural form of ''rimi'' which means "ridge". Coat-of-arms The coat-of-arms is from modern time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eider
The eiders () are large seaducks in the genus ''Somateria''. The three extant species all breed in the cooler latitudes of the Northern Hemisphere. The down feathers of eider ducks and some other ducks and geese are used to fill pillows and quilts—they have given the name to the type of quilt known as an eiderdown. Taxonomy The genus ''Somateria '' was introduced in 1819 to accommodate the king eider by the English zoologist William Leach in an appendix to John Ross's account of his voyage to look for the Northwest Passage. The name is derived from Ancient Greek : ''sōma'' "body" (stem ''somat-'') and : ''erion'' "wool", referring to eiderdown. Steller's eider (''Polysticta stelleri'') is in a different genus despite its name. Species The genus contains three extant species. Two undescribed species are known from fossils, one from Middle Oligocene rocks in Kazakhstan and another from the Late Miocene or Early Pliocene of Lee Creek Mine, United States. ...

Cormorant
Phalacrocoracidae is a family of approximately 40 species of aquatic birds commonly known as cormorants and shags. Several different classifications of the family have been proposed, but in 2021 the International Ornithologists' Union (IOU) adopted a consensus taxonomy of seven genera. The great cormorant (''Phalacrocorax carbo'') and the common shag (''Gulosus aristotelis'') are the only two species of the family commonly encountered in Britain and Ireland, and the names "cormorant" and "shag" have been later assigned to different species in the family somewhat haphazardly. Cormorants and shags are medium-to-large birds, with body weight in the range of and wing span of . The majority of species have dark feathers. The bill is long, thin and hooked. Their feet have webbing between all four toes. All species are fish-eaters, catching the prey by diving from the surface. They are excellent divers, and under water they propel themselves with their feet with help from their wing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Osprey
The osprey (; ''Pandion haliaetus''), historically known as sea hawk, river hawk, and fish hawk, is a diurnal, fish-eating bird of prey with a cosmopolitan range. It is a large raptor, reaching more than in length and a wingspan of . It is brown on the upperparts and predominantly greyish on the head and underparts. The osprey tolerates a wide variety of habitats, nesting in any location near a body of water providing an adequate food supply. It is found on all continents except Antarctica, although in South America it occurs only as a non-breeding migrant. As its other common names suggest, the osprey's diet consists almost exclusively of fish. It possesses specialised physical characteristics and unique behaviour in hunting its prey. Because of its unique characteristics it is classified in its own taxonomic genus, ''Pandion'', and family, Pandionidae. Taxonomy The osprey was described in 1758 by the Swedish naturalist Carl Linnaeus under the name ''Falco haliaetus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moose
The moose (: 'moose'; used in North America) or elk (: 'elk' or 'elks'; used in Eurasia) (''Alces alces'') is the world's tallest, largest and heaviest extant species of deer and the only species in the genus ''Alces''. It is also the tallest, and the second-largest, land animal in North America, falling short only to the American bison in body mass. Most adult male moose have broad, palmate ("open-hand shaped") antlers; other members of the deer family have pointed antlers with a dendritic ("twig-like") configuration. Moose inhabit the circumpolar boreal forests or temperate broadleaf and mixed forests of the Northern Hemisphere, thriving in cooler, temperate areas as well as subarctic climates. Hunting shaped the relationship between moose and humans, both in Eurasia and North America. Prior to the colonial era (around 1600–1700 CE), moose were one of many valuable sources of sustenance for certain tribal groups and First Nations. Hunting and habitat loss hav ...

Coniferous Forest
Conifers () are a group of cone-bearing seed plants, a subset of gymnosperms. Scientifically, they make up the division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class, Pinopsida. All extant conifers are perennial woody plants with secondary growth. The majority are trees, though a few are shrubs. Examples include cedars, Douglas-firs, cypresses, firs, junipers, kauri, larches, pines, hemlocks, redwoods, spruces, and yews.Campbell, Reece, "Phylum Coniferophyta". ''Biology''. 7th ed. 2005. Print. p. 595. As of 2002, Pinophyta contained seven families, 60 to 65 genera, and more than 600 living species. Although the total number of species is relatively small, conifers are ecologically important. They are the dominant plants over large areas of land, most notably the taiga of the Northern Hemisphere, but also in similar cool climates in mountains further south. Boreal conifers have many wintertime adaptations. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quartzite
Quartzite is a hard, non- foliated metamorphic rock that was originally pure quartz sandstone.Essentials of Geology, 3rd Edition, Stephen Marshak, p 182 Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts, and hence quartzite is a metasandstone. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of hematite. Other colors, such as yellow, green, blue and orange, are due to other minerals. The term ''quartzite'' is also sometimes used for very hard but unmetamorphosed sandstones that are composed of quartz grains thoroughly cemented with additional quartz. Such sedimentary rock has come to be described as orthoquartzite to distinguish it from metamorphic quartzite, which is sometimes called metaquartzite to emphasize its metamorphic origins. Quartzite is very resistant to chemical weathering and often forms ridges and resist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
