Kamenitza (Geomorphology)
Kamenitzas or solution pans are closed depressions that develop on rock surfaces in karst regions formed by dissolution weathering. Usually they form on horizontal, or slightly inclined limestone pavements where water does not flow but collects into the small depressions. The presence of static water produces small, round, closed pans that are shallow as compared with their depth. Usually they have a diameter of several decimeters, but kamenitzas with a diameter up to 6 m have been documented. Overflow usually creates a solution runnel (karren). This overflow channel often lowers to the extent that it reaches the kamenitza bottom, where further development stops and the pan does not widen any longer. The name kamenitza is of Slavic origin where ''kamen'' means pebble. It came from the wrong hypothesis that small pebbles rotating in a water flow are forming the kamenitzas.

Kamenitza In Den Karen Totes Gebirge 20221023c
Kamenitza ( bg, Каменица) is one of the top-selling Bulgarian beer companies, alongside Heineken and Astika based in the city of Haskovo. It was established in 1881 and is currently owned by the multinational Molson Coors. The brewery has a wide variety of lager and dark beers. Its slogan is "Mazhete znayat zashto" which translates to "Men know why." Kamenitza had an 18% share of the Bulgarian beer market in 2005 according to data from ACNielsen. The company is a sponsor of the Bulgaria national football team. Kamenitza currently has six brands: Light (4.4% ABV), Dark (6% ABV), non-alcoholic, wheat and Fresh (lemon- and grapefruit-flavoured, 2.1% ABV).Kamenitza brands Kamenitza.bg. Retrieved Mar 2013.

Karst
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German in the late 19th century, which entered German much earlier ...

Weathering
Weathering is the deterioration of rocks, soils and minerals as well as wood and artificial materials through contact with water, atmospheric gases, and biological organisms. Weathering occurs ''in situ'' (on site, with little or no movement), and so is distinct from erosion, which involves the transport of rocks and minerals by agents such as water, ice, snow, wind, waves and gravity. Weathering processes are divided into ''physical'' and ''chemical weathering''. Physical weathering involves the breakdown of rocks and soils through the mechanical effects of heat, water, ice, or other agents. Chemical weathering involves the chemical reaction of water, atmospheric gases, and biologically produced chemicals with rocks and soils. Water is the principal agent behind both physical and chemical weathering, though atmospheric oxygen and carbon dioxide and the activities of biological organisms are also important. Chemical weathering by biological action is also known as biological wea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone Pavement
A limestone pavement is a natural karst landform consisting of a flat, incised surface of exposed limestone that resembles an artificial pavement. The term is mainly used in the UK and Ireland, where many of these landforms have developed distinctive surface patterning resembling paving blocks. Similar landforms in other parts of the world are known as alvars. Formation of a limestone pavement Conditions for limestone pavements are created when an advancing glacier scrapes away overburden and exposes horizontally bedded limestone, with subsequent glacial retreat leaving behind a flat, bare surface. Limestone is slightly soluble in water and especially in acid rain, so corrosive drainage along joints and cracks in the limestone can produce slabs called ''clints'' isolated by deep fissures called ''grikes'' or ''grykes'' (terms derived from a northern English dialect). If the grykes are fairly straight and the clints are uniform in size, the resemblance to man-made paving stone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slavic Languages
The Slavic languages, also known as the Slavonic languages, are Indo-European languages spoken primarily by the Slavic peoples and their descendants. They are thought to descend from a proto-language called Proto-Slavic, spoken during the Early Middle Ages, which in turn is thought to have descended from the earlier Proto-Balto-Slavic language, linking the Slavic languages to the Baltic languages in a Balto-Slavic group within the Indo-European family. The Slavic languages are conventionally (that is, also on the basis of extralinguistic features) divided into three subgroups: East, South, and West, which together constitute more than 20 languages. Of these, 10 have at least one million speakers and official status as the national languages of the countries in which they are predominantly spoken: Russian, Belarusian and Ukrainian (of the East group), Polish, Czech and Slovak (of the West group) and Bulgarian and Macedonian (eastern dialects of the South group), and Serbo-C ...

Panhole
A panhole is a depression or basin eroded into flat or gently sloping cohesive rock.Twidale, C.R., and Bourne, J.A., 2018''Rock basins (gnammas) revisited.
