Ostrobothnian Plain
The Ostrobothnian Plain or Pohjanmaa is a large lowland in Finland along the Bothnian Sea being arguably the largest plain in the Nordic countries. The plain is made up smaller individual sand and clay plains alternated with rivers and peat bogs. It extends as a 100 km wide and 257 km long belt along the northwestern coast of Finland. The plain is extremely flat with height differences never exceeding 50 m. Geologically the plain is a continuation of the Sub-Cambrian peneplain found across much of Fennoscandia.

Finland
Finland, officially the Republic of Finland, is a Nordic country in Northern Europe. It borders Sweden to the northwest, Norway to the north, and Russia to the east, with the Gulf of Bothnia to the west and the Gulf of Finland to the south, opposite Estonia. Finland has a population of 5.6 million. Its capital and largest city is Helsinki. The majority of the population are Finns, ethnic Finns. The official languages are Finnish language, Finnish and Swedish language, Swedish; 84.1 percent of the population speak the first as their mother tongue and 5.1 percent the latter. Finland's climate varies from humid continental climate, humid continental in the south to boreal climate, boreal in the north. The land cover is predominantly boreal forest biome, with List of lakes of Finland, more than 180,000 recorded lakes. Finland was first settled around 9000 BC after the Last Glacial Period, last Ice Age. During the Stone Age, various cultures emerged, distinguished by differen ...

Bothnian Sea
The Bothnian Sea (; ) links the Bothnian Bay (also called the Bay of Bothnia) with the Baltic Sea, Baltic proper. Kvarken is situated between the two. Together, the Bothnian Sea and Bay make up a larger geographical entity, the Gulf of Bothnia, where the Bothnian Sea is the southern part. The whole Gulf of Bothnia is situated between Sweden, to the west, Finland, to the east, and the Sea of Åland and Archipelago Sea to the south. The surface area of the Bothnian Sea is approximately . The largest coastal towns, from south to north, are Rauma, Finland, Rauma and Pori in Finland, and Gävle and Sundsvall in Sweden. Umeå (Sweden) and Vaasa (Finland) lie in the extreme north, near Bothnian Bay.

Nordic Countries
The Nordic countries (also known as the Nordics or ''Norden''; ) are a geographical and cultural region in Northern Europe, as well as the Arctic Ocean, Arctic and Atlantic Ocean, North Atlantic oceans. It includes the sovereign states of Denmark, Finland, Iceland, Norway and Sweden; the autonomous administrative division, autonomous territories of the Faroe Islands and Greenland; and the autonomous region of Åland. The Nordic countries have much in common in their way of life, History of Scandinavia, history, religion and Nordic model, social and economic model. They have a long history of political unions and other close relations but do not form a singular state or federation today. The Scandinavism, Scandinavist movement sought to unite Denmark, Norway and Sweden into one country in the 19th century. With the dissolution of the union between Norway and Sweden (Norwegian independence), the independence of Finland in the early 20th century and the 1944 Icelandic constitution ...

Sand
Sand is a granular material composed of finely divided mineral particles. Sand has various compositions but is usually defined by its grain size. Sand grains are smaller than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass. The composition of sand varies, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non-tropical coastal settings is silica (silicon dioxide, or SiO2), usually in the form of quartz. Calcium carbonate is the second most common type of sand. One such example of this is aragonite, which has been created over the past 500million years by various forms of life, such as coral and shellfish. It is the primary form of sand apparent in areas where reefs have dominated the ecosystem for millions of years, as in the Caribbean. Somewhat more rarely, sand may be composed ...

Clay
Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolinite, ). Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide. Clays develop plasticity (physics), plasticity when wet but can be hardened through Pottery#Firing, firing. Clay is the longest-known ceramic material. Prehistoric humans discovered the useful properties of clay and used it for making pottery. Some of the earliest pottery shards have been radiocarbon dating, dated to around 14,000 BCE, and Clay tablet, clay tablets were the first known writing medium. Clay is used in many modern industrial processes, such as paper making, cement production, and chemical filtration, filtering. Between one-half and two-thirds of the world's population live or work in buildings made with clay, often baked into brick, as an essenti ...

Peat Bog
A bog or bogland is a wetland that accumulates peat as a deposit of dead plant materials often mosses, typically sphagnum moss. It is one of the four main types of wetlands. Other names for bogs include mire, mosses, quagmire, and muskeg; alkaline mires are called fens. A bayhead is another type of bog found in the forest of the Gulf Coast states in the United States.Watson, Geraldine Ellis (2000) ''Big Thicket Plant Ecology: An Introduction'', Third Edition (Temple Big Thicket Series #5).

Sub-Cambrian Peneplain
The sub-Cambrian peneplain is an ancient, extremely flat, erosion surface (peneplain) that has been exhumed and exposed by erosion from under Cambrian strata over large swathes of Fennoscandia. Eastward, where this peneplain dips below Cambrian and other Lower Paleozoic cover rocks. The outcrop, exposed parts of this peneplain are extraordinarily flat with relief of less than 20 m. The overlying cover rocks demonstrate that the peneplain was flooded by epicontinental sea, shallow seas during the Early Paleozoic. Being the oldest identifiable peneplain in its area the Sub-Cambrian peneplain qualifies as a primary peneplain. The surface was first identified by Arvid Högbom in a 1910 publication, with Sten Rudberg publishing the first extensive map in 1954. This mapping has been improved upon by Karna Lidmar-Bergström since the 1980s. Extent The Sub-Cambrian peneplain extends as an almost continuous belt along the eastern coast of Sweden for some 700 km from north to south. Near St ...

Fennoscandia
__NOTOC__ Fennoscandia (Finnish language, Finnish, Swedish language, Swedish and ; ), or the Fennoscandian Peninsula, is a peninsula in Europe which includes the Scandinavian Peninsula, Scandinavian and Kola Peninsula, Kola peninsulas, mainland Finland, and Karelia. Administratively, this roughly encompasses the mainlands of Finland, Norway and Sweden, as well as Murmansk Oblast, much of the Republic of Karelia, and parts of northern Leningrad Oblast in Russia. Its name comes from the Latin words ''Fennia'' (Finland) and ''Scandia'' (Scandinavia). The term was first used by the Finnish geologist Wilhelm Ramsay in 1898. Geologically, the area is distinct because its bedrock is Archean granite and gneiss with very little limestone, in contrast to adjacent areas in Europe. The similar term Fenno-Scandinavia is sometimes used for Fennoscandia. Both terms are sometimes used in English to refer to a cultural or political grouping of Finland with Sweden, Norway and Denmark (the latter ...

Nationalencyklopedin
(; "The National Encyclopedia" in English), abbreviated NE, is a comprehensive contemporary Swedish-language encyclopedia with several hundred thousand articles. It is available both online and via a printed version. History The project was initiated in 1980 when a government committee suggested that negotiations be initiated with various publishers. A loan from the Government of Sweden of 17 million Swedish krona, which was repaid by December 1990, provided funding. In August 1985, in Höganäs became the publisher responsible for the project. The project specifications were for a modern reference work based on a scientific paradigm incorporating gender and environmental issues. Pre-orders for the work were unprecedented; before the first volume was published in December 1989, 54,000 customers had ordered the encyclopedia. The last volume came out in 1996, with three supplemental volumes in 2000. 160,000 copies had been sold as of 2004. Associated with the project ...

Landforms Of Ostrobothnia (administrative Region)
A landform is a land feature on the solid surface of the Earth or other planetary body. They may be natural or may be anthropogenic (caused or influenced by human activity). Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great oceanic basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type. Gross physical features or landforms include intuitive elements such as berms, cliffs, hills, mounds, peninsulas, ridges, rivers, valleys, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodi ...
