Muddus Plains
The Muddus plains is a landscape type in northern Sweden characterized by its flat topography dotted with inselbergs. The topographic character of the Muddus plains was first described in detail by Walter Wråk in 1908. The Muddus plains are part of the Norrland terrain. The northern lower levels of Southern Norway's Paleic surface are considered to be equivalent to the Muddus plains. The plains formed in connection to the uplift of the northern Scandinavian Mountains in the Paleogene. The uplift caused the surface to tilt eastward and incised valleys opened up to the east. This region in to east of the Scandinavian Mountains proper was a tectonically stable region close to a base level where topography evolved to form the Muddus plains. The key processes involved in the formation of the Muddus plain include etching, stripping and pediplanation. The climate under which these processes occurred was likely warm relative to the present. To the south the Muddus plains is considere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jokkmokk Utsikt Från Storknabben
Jokkmokk (; smj, Jåhkåmåhkke or ; se, Dálvvadis; fi, Jokimukka) is a locality and the seat of Jokkmokk Municipality in Norrbotten County, province of Lapland, Sweden, with 2,786 inhabitants in 2010. The Lule Sami name of the place (composed of the individual words and ) means "River's Curve," due to the meandering river that runs through it. As in other towns in Lapland, the Swedish language is dominant at an official level in Jokkmokk in modern times. The settlement is just north of the Arctic Circle. Talvatissjön is located at the southern part of Jokkmokk. Jokkmokk is an important locality for Sámi people and the location of several institutions related to them, including an education centre, the Ájtte museum, and an office of the Sámi Parliament of Sweden. Jokkmokk was a transit center for Sami refugees from Norway during World War II, in addition to the centre in Kjesäter. Jokkmokk Market has been taking place since 1605. On the first Thursday in February every y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pediplain
In geology and geomorphology a pediplain (from the Latin ''pes'', genitive case ''pedis'', meaning "foot") is an extensive plain formed by the coalescence of pediments. The processes through which pediplains forms is known as pediplanation. The concepts of pediplain and pediplanation were first developed by geologist Lester Charles King in his 1942 book ''South African Scenery''. The concept gained notoriety as it was juxtaposed to peneplanation. The coalesced pediments of the pediplains may form a series of very gentle concave slopes. Pediplains main difference to W. M. Davis’ peneplains is in the history and processes behind, and less so in the final shape. Perhaps the most notable difference in form that may be present is that of residual hills which in Davis’ peneplains are to have gentle slopes while in pediplains they ought to have the same steepness as the slopes in the early stages of erosion leading to pediplanation. Pediplanation is linked to scarp retreat in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plains Of Sweden
In geography, a plain is a flat expanse of land that generally does not change much in elevation, and is primarily treeless. Plains occur as lowlands along valleys or at the base of mountains, as coastal plains, and as plateaus or uplands. In a valley, a plain is enclosed on two sides, but in other cases a plain may be delineated by a complete or partial ring of hills, by mountains, or by cliffs. Where a geological region contains more than one plain, they may be connected by a pass (sometimes termed a gap). Coastal plains mostly rise from sea level until they run into elevated features such as mountains or plateaus. Plains are one of the major landforms on earth, where they are present on all continents, and cover more than one-third of the world's land area. Plains can be formed from flowing lava; from deposition of sediment by water, ice, or wind; or formed by erosion by the agents from hills and mountains. Biomes on plains include grassland (temperate or subtropical), ste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inselberg Plains
An inselberg or monadnock () is an isolated rock hill, knob, ridge, or small mountain that rises abruptly from a gently sloping or virtually level surrounding plain. In Southern Africa a similar formation of granite is known as a koppie, an Afrikaans word ("little head") from the Dutch diminutive word ''kopje''. If the inselberg is dome-shaped and formed from granite or gneiss, it can also be called a bornhardt, though not all bornhardts are inselbergs. An inselberg results when a body of rock resistant to erosion, such as granite, occurring within a body of softer rocks, is exposed by differential erosion and lowering of the surrounding landscape. Etymology Inselberg The word ''inselberg'' is a loan word from German, and means "island mountain". The term was coined in 1900 by geologist Wilhelm Bornhardt (1864–1946) to describe the abundance of such features found in eastern Africa. At that time, the term applied only to arid landscape features. However, it has sinc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muddus National Park
Muddus (; smj, Muttos) is a national park in northern Sweden. It is situated in the province Lapland, with its largest part in the Gällivare Municipality. Furthermore, it belongs to the largely untouched UNESCO World Heritage classified Laponian area. Natural scenes include the old-growth forest with large trees, large boggy grounds, and deep ravines in between the rocks. Sweden's oldest known pine tree is also located here. It has been estimated to be at least 710 years old, as it was found to have withstood a forest fire in 1413. Wildfires Forest fires in the Muddus National Park have left traces on sample plots. There are fire scars on living or dead trees or charcoal fragments in the humus layer. The park was investigated on 75 separate sample plots. Some of the major fire years in the Muddus area coincide with forest fires in other parts of northern Sweden, in the taiga of western Russia, and in central Siberia. There is constant regeneration happening in the wild ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lapland (Finland)
Lapland ( fi, Lappi ; se, Lappi; smn, Laapi; sv, Lappland; la, Lapponia, links=no) is the largest and northernmost region of Finland. The 21 municipalities in the region cooperate in a Regional Council. Lapland borders the region of North Ostrobothnia in the south. It also borders the Gulf of Bothnia, Norrbotten County in Sweden, Troms and Finnmark County in Norway, and Murmansk Oblast and the Republic of Karelia in Russia. Topography varies from vast mires and forests of the South to fells in the North. The Arctic Circle crosses Lapland, so polar phenomena such as the midnight sun and polar night can be viewed in Lapland. Lapland's cold and wintry climate, coupled with its relative abundance of conifer trees such as pines and spruces, means that it has become associated with Christmas in some countries, most notably the United Kingdom, and holidays to Lapland are common towards the end of the year. However, the Lapland region has developed its infrastructure for year-round ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gulf Of Bothnia
The Gulf of Bothnia (; fi, Pohjanlahti; sv, Bottniska viken) is divided into the Bothnian Bay and Bothnian Sea, and it is the northernmost arm of the Baltic Sea, between Finland's west coast ( East Bothnia) and the Sweden's east coast (West Bothnia and North Bothnia). In the south of the gulf lies Åland, between the Sea of Åland and the Archipelago Sea. Name Bothnia is a latinization. The Swedish name was originally just , with being Old Norse for "gulf" or "bay", which is also the meaning of the second element . The name was applied to the Gulf of Bothnia as in Old Norse, after , which at the time referred to the coastland west of the gulf. Later, was applied to the regions on the western side and the eastern side ('East Bottom' and 'West Bottom'). The Finnish name of Österbotten, (, meaning 'land'), gives a hint as to the meaning in both languages: the meaning of includes both 'bottom' and 'north'. is the base word for north, , with an adjectival suffix adde ...

Cenozoic
The Cenozoic ( ; ) is Earth's current geological era, representing the last 66million years of Earth's history. It is characterised by the dominance of mammals, birds and flowering plants, a cooling and drying climate, and the current configuration of continents. It is the latest of three geological eras since complex life evolved, preceded by the Mesozoic and Paleozoic. It started with the Cretaceous–Paleogene extinction event, when many species, including the non-avian dinosaurs, became extinct in an event attributed by most experts to the impact of a large asteroid or other celestial body, the Chicxulub impactor. The Cenozoic is also known as the Age of Mammals because the terrestrial animals that dominated both hemispheres were mammalsthe eutherians (placentals) in the northern hemisphere and the metatherians (marsupials, now mainly restricted to Australia) in the southern hemisphere. The extinction of many groups allowed mammals and birds to greatly diversify so that l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drainage System (geomorphology)
In geomorphology, drainage systems, also known as river systems, are the patterns formed by the streams, rivers, and lakes in a particular drainage basin. They are governed by the topography of land, whether a particular region is dominated by hard or soft rocks, and the gradient of the land. Geomorphologists and hydrologists often view streams as part of drainage basins (and sub-basins). This is the topographic region from which a stream receives runoff, throughflow, and its saturated equivalent, groundwater flow. The number, size, and shape of the drainage basins varies and the larger and more detailed the topographic map, the more information is available. Drainage patterns Per the lie of channels, drainage systems can fall into one of several categories, known as drainage patterns. These depend on the topography and geology of the land. All forms of transitions can occur between parallel, dendritic, and trellis patterns. Accordant versus discordant drainage patterns A drai ...

Paleic Surface
The paleic surface or palaeic surface ( no, paleiske overflaten, ) is an erosion surface of gentle slopes that exist in South Norway. Parts of it are a continuation of the Sub-Cambrian peneplain and Muddus Plains found further east or equivalent to the strandflat coastal plains of Norway. Hardangervidda, a particularly flat and elevated part of the Paleic surface formed in the Miocene at sea level. Although the tilted plateau-like topography of south Norway had been noted since the early 1800s, the first formal description was by Hans Reusch in 1901, using a denudation chronology approach invoking several of W.M. Davis’ ideas of a cycle of erosion. Reusch also coined the name ''Paleic surface''. The Paleic surface is sometimes erroneously considered equal to Norway's "pre-glacial surface" – the surface that existed in Norway just before the Quaternary glaciations.

Erosion
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical erosion procee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
