Rock Carvings At Alta
The Rock art of Alta (''Helleristningene i Alta'') are located in and around the municipality of Alta in the county of Finnmark in northern Norway. Since the first carvings were discovered in 1973, more than 6000 carvings have been found on several sites around Alta. The largest locality, at Jiepmaluokta about 5 kilometres from Alta, contains thousands of individual carvings and has been turned into an open-air museum. The site, along with the sites Storsteinen, Kåfjord, Amtmannsnes and Transfarelv, was placed on the UNESCO list of World Heritage Sites on 3 December 1985. It is Norway's only prehistoric World Heritage Site. The carvings were divided into five separate groups by Professor Knut Helskog, of the Department of Cultural Sciences at the University of Tromsø. Using shoreline dating, the earliest carvings were dated to around 4200 BC; the most recent carvings were dated to around 500 BC. In 2010 researcher Jan Magne Gjerde pushed the dates for the oldest phases bac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alta, Norway
( se, Áltá ; fkv, Alattio; fi, Alattio) is the most populated municipality in Finnmark in Troms og Finnmark county, Norway. The administrative centre of the municipality is the town of Alta. Some of the main villages in the municipality include Kåfjord, Komagfjord, Kvenvik, Langfjordbotn, Leirbotn, Rafsbotn, Talvik, and Tverrelvdalen. Downtown Alta is located just below the 70th latitude and is closer to the North Pole than it is to much of Central Europe and the British Isles. The town is the northernmost settlement of urban significance in the European Economic Area, with municipalities north of it being sparsely populated. In spite of its high latitude the local climate is seldom severy cold thanks to Gulf Stream moderation in the prevailing wind. As a result of its shielded position leading to mild summers, the coastal areas of the municipality are warm enough to enable forestation. Due to Norway curving above its Nordic neighbours, Alta is located further e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shamanism
Shamanism is a religious practice that involves a practitioner (shaman) interacting with what they believe to be a spirit world through altered states of consciousness, such as trance. The goal of this is usually to direct spirits or spiritual energies into the physical world for the purpose of healing, divination, or to aid human beings in some other way. Beliefs and practices categorized as "shamanic" have attracted the interest of scholars from a variety of disciplines, including anthropologists, archeologists, historians, religious studies scholars, philosophers and psychologists. Hundreds of books and academic papers on the subject have been produced, with a peer-reviewed academic journal being devoted to the study of shamanism. In the 20th century, non- Indigenous Westerners involved in countercultural movements, such as hippies and the New Age created modern magicoreligious practices influenced by their ideas of various Indigenous religions, creating what has been ...

Scandinavia
Scandinavia; Sámi languages: /. ( ) is a subregion in Northern Europe, with strong historical, cultural, and linguistic ties between its constituent peoples. In English usage, ''Scandinavia'' most commonly refers to Denmark, Norway, and Sweden. It can sometimes also refer more narrowly to the Scandinavian Peninsula (which excludes Denmark but includes part of Finland), or more broadly to include all of Finland, Iceland, and the Faroe Islands. The geography of the region is varied, from the Norwegian fjords in the west and Scandinavian mountains covering parts of Norway and Sweden, to the low and flat areas of Denmark in the south, as well as archipelagos and lakes in the east. Most of the population in the region live in the more temperate southern regions, with the northern parts having long, cold, winters. The region became notable during the Viking Age, when Scandinavian peoples participated in large scale raiding, conquest, colonization and trading mostly throughout ...

Post-glacial Rebound
Post-glacial rebound (also called isostatic rebound or crustal rebound) is the rise of land masses after the removal of the huge weight of ice sheets during the last glacial period, which had caused isostatic depression. Post-glacial rebound and isostatic depression are phases of glacial isostasy (glacial isostatic adjustment, glacioisostasy), the deformation of the Earth's crust in response to changes in ice mass distribution. The direct raising effects of post-glacial rebound are readily apparent in parts of Northern Eurasia, Northern America, Patagonia, and Antarctica. However, through the processes of ''ocean siphoning'' and ''continental levering'', the effects of post-glacial rebound on sea level are felt globally far from the locations of current and former ice sheets.Milne, G.A., and J.X. Mitrovica (2008) ''Searching for eustasy in deglacial sea-level histories.'' Quaternary Science Reviews. 27:2292–2302. Overview During the last glacial period, much of northern E ...

Alta Museum
The World Heritage Rock Art Centre - Alta Museum (''Verdensarvsenter for bergkunst – Alta Museum'') is located at Alta in Troms og Finnmark, Norway. World Heritage Rock Art - Alta Museum is situated in Hjemmeluft, a small bay in the Altafjord at a site of early settlement of Finnmark dating from around 11,000 years ago. In 1973, the first rock carvings in Hjemmeluft were found. To date over 3,000 figures have been registered here. In the municipality as a whole over 6000 figures have been registered. The museum opened in June 1991 and won the European Museum of the Year Award in 1993. Alta Museum is northern Norway's most-visited summer museum, with more than 1,000 visitors each day. It is the second most visited attraction in Finnmark County. It presents exhibitions on local culture and historic industries including the nearby prehistoric rock carvings that form a UNESCO World Heritage Site A World Heritage Site is a landmark or area with legal protection by an intern ...

Hardness
In materials science, hardness (antonym: softness) is a measure of the resistance to localized plastic deformation induced by either mechanical indentation or abrasion. In general, different materials differ in their hardness; for example hard metals such as titanium and beryllium are harder than soft metals such as sodium and metallic tin, or wood and common plastics. Macroscopic hardness is generally characterized by strong intermolecular bonds, but the behavior of solid materials under force is complex; therefore, hardness can be measured in different ways, such as scratch hardness, indentation hardness, and rebound hardness. Hardness is dependent on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity. Common examples of hard matter are ceramics, concrete, certain metals, and superhard materials, which can be contrasted with soft matter. Measuring hardness There are three main types of hardness measurements: ''s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hammer
A hammer is a tool, most often a hand tool, consisting of a weighted "head" fixed to a long handle that is swung to deliver an impact to a small area of an object. This can be, for example, to drive nails into wood, to shape metal (as with a forge), or to crush rock. Hammers are used for a wide range of driving, shaping, breaking and non-destructive striking applications. Traditional disciplines include carpentry, blacksmithing, warfare, and percussive musicianship (as with a gong). Hammering is use of a hammer in its strike capacity, as opposed to prying with a secondary claw or grappling with a secondary hook. Carpentry and blacksmithing hammers are generally wielded from a stationary stance against a stationary target as gripped and propelled with one arm, in a lengthy downward planar arc—downward to add kinetic energy to the impact—pivoting mainly around the shoulder and elbow, with a small but brisk wrist rotation shortly before impact; for extreme impact ...

Chisel
A chisel is a tool with a characteristically shaped cutting edge (such that wood chisels have lent part of their name to a particular grind) of blade on its end, for carving or cutting a hard material such as wood, stone, or metal by hand, struck with a mallet, or mechanical power. The handle and blade of some types of chisel are made of metal or of wood with a sharp edge in it. Chiselling use involves forcing the blade into some material to cut it. The driving force may be applied by pushing by hand, or by using a mallet or hammer. In industrial use, a hydraulic ram or falling weight (' trip hammer') may be used to drive a chisel into the material. A gouge (one type of chisel) serves to carve small pieces from the material, particularly in woodworking, woodturning and sculpture. Gouges most frequently produce concave surfaces. A gouge typically has a 'U'-shaped cross-section. Etymology ''Chisel'' comes from the Old French ''cisel'', modern ''ciseau'', Late Latin ' ...

Quartzite
Quartzite is a hard, non- foliated metamorphic rock which 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. 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 resistant hilltops. The nearly pure silica co ...

Russia
Russia (, , ), or the Russian Federation, is a transcontinental country spanning Eastern Europe and Northern Asia. It is the largest country in the world, with its internationally recognised territory covering , and encompassing one-eighth of Earth's inhabitable landmass. Russia extends across eleven time zones and shares land boundaries with fourteen countries, more than any other country but China. It is the world's ninth-most populous country and Europe's most populous country, with a population of 146 million people. The country's capital and largest city is Moscow, the largest city entirely within Europe. Saint Petersburg is Russia's cultural centre and second-largest city. Other major urban areas include Novosibirsk, Yekaterinburg, Nizhny Novgorod, and Kazan. The East Slavs emerged as a recognisable group in Europe between the 3rd and 8th centuries CE.

Tool
A tool is an object that can extend an individual's ability to modify features of the surrounding environment or help them accomplish a particular task. Although many animals use simple tools, only human beings, whose use of stone tools dates back hundreds of millennia, have been observed using tools to make other tools. Early human tools, made of such materials as stone, bone, and wood, were used for preparation of food, hunting, manufacture of weapons, and working of materials to produce clothing and useful artifacts. The development of metalworking made additional types of tools possible. Harnessing energy sources, such as animal power, wind, or steam, allowed increasingly complex tools to produce an even larger range of items, with the Industrial Revolution marking an inflection point in the use of tools. The introduction of widespread automation in the 19th and 20th centuries allowed tools to operate with minimal human supervision, further increasing the productivity ...

Metal
A metal (from Greek μέταλλον ''métallon'', "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically ductile (can be drawn into wires) and malleable (they can be hammered into thin sheets). These properties are the result of the ''metallic bond'' between the atoms or molecules of the metal. A metal may be a chemical element such as iron; an alloy such as stainless steel; or a molecular compound such as polymeric sulfur nitride. In physics, a metal is generally regarded as any substance capable of conducting electricity at a temperature of absolute zero. Many elements and compounds that are not normally classified as metals become metallic under high pressures. For example, the nonmetal iodine gradually becomes a metal at a pressure of between 40 and 170 thousand times atmospheric pressure. Equally, some materials regarded as metals c ...
