Slovak Karst
The Slovak Karst () is one of the mountain ranges of the Slovenské Rudohorie mountains in the Carpathian Mountains, Carpathians in southern Slovakia. It consists of a complex of huge karst plains and plateaus. Since 1973 it has been a protected landscape area. On 1 March 2002 Slovak Karst National Park was declared. It is also a UNESCO Biosphere Reserve and part of it forms UNESCO World Heritage Site Caves of Aggtelek Karst and Slovak Karst. Characteristics The highest peak is Jelení vrch at 947 m AMSL. Important rivers are the Sajó, Slaná (Sajó), the Štítnik and the Turňa (river), Turňa. The Slovak Karst lies in the north temperate zone and has a continental climate with four distinct seasons. The area is composed of several layers of Mesozoic limestone and Dolomite (rock), dolomite, beneath which there is non-permeable sandstone, limestone and slate. The plains are covered by oak-hornbeam forests, the hills by oak forests and the karst pits by spruce forests. Beech for ... [...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 ...

Gombasek Cave
Gombasek Cave or Gombasecká jaskyňa (in Slovak) and Gombaszögi-barlang (in Hungarian) is a karst cave in the Slovak Karst, Slovakia. It is named after the settlement of ''Gombasek'', which belongs to the village of Slavec. It is located in the Slovak Karst National Park, in the Slaná river valley, approximately 15 km south of Rožňava. The cave was discovered on 21 November 1951 by volunteer cavers. In 1955, 285 m out of 1 525 m were opened to the public. Currently, the route for visitors is 530 m long and takes about 30 minutes. The cave was also used for "speleotherapy" as a sanatorium, focused on airway diseases. Since 1995, the Gombasek Cave is included in the UNESCO World Heritage List as a part of the Caves of Aggtelek Karst and Slovak Karst site because of its exemplary speleothems and its record of karst formation under varying conditions, including periods of glaciation and temperate, and tropical climatic conditions.

Ochtinská Aragonite Cave
Ochtinská Aragonite Cave (, the Magyar Wikipedia article uses a different title) is a unique aragonite cave situated in southern Slovakia, near Rožňava. Although only 300 m long, it is famous for its rare aragonite formations. Along with other caves of the Slovak Karst, it is included in the UNESCO World Heritage list as a component of Caves of Aggtelek Karst and Slovak Karst site, because of its diversity of aragonite formations and testimony to the cave-forming geologic processes. Description The Ochtinská Aragonite Cave is one of only three aragonite caves discovered in the world so far. The cave is located at 642 meters above sea level, with an temperature between 7.2 and 7.8°C. This stable microclimate, along with dissolved iron, manganese, and magnesium ion is the slowly dripping water, allows for the formation of the ornate aragonite formations. The oldest of these formations are between 120,000 and 130,000 years old, with younger formations being about 14,000 year ...

Domica
The Domica cave is a karst cave situated on the south-western border of the ''Silicka planina Plateau'' south-east of Plesivec in the Rožňava District of the Košice Region in southern Slovakia. In combination with the Baradla cave, it makes up the most significant section of the ''Aggtelek Karst and Slovak Karst'' cross-border cave network that continues into the Aggtelek National Park in Hungary. The cave is well-known for its complex structure and high density of speleothems. These vast limestone passages, that had formed during the Middle Triassic and are rich in speleothems were discovered in 1926 by Ján Majko. A section of its total length of has been publicly accessible since 1932. As an element of the ''Caves of Aggtelek Karst and Slovak Karst'' the site was listed as a UNESCO World Heritage Site list in 1995 because of the diversity of cave features found within it and its record of both tropical and temperate effects on karst cave formation.

Cave
Caves or caverns are natural voids under the Earth's Planetary surface, surface. Caves often form by the weathering of rock and often extend deep underground. Exogene caves are smaller openings that extend a relatively short distance underground (such as rock shelters). Caves which extend further underground than the opening is wide are called endogene caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called Caving, ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorganisms, pressure, and atmospheric influences. Isotopic dating techniques can be applied to cave sedime ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Beech
Beech (genus ''Fagus'') is a genus of deciduous trees in the family Fagaceae, native to subtropical (accessory forest element) and temperate (as dominant element of Mesophyte, mesophytic forests) Eurasia and North America. There are 14 accepted species in two distinct subgenera, ''Englerianae'' and ''Fagus''. The subgenus ''Englerianae'' is found only in East Asia, distinctive for its low branches, often made up of several major trunks with yellowish bark. The better known species of subgenus ''Fagus'' are native to Europe, western and eastern Asia and eastern North America. They are high-branching trees with tall, stout trunks and smooth silver-grey bark. The European beech ''Fagus sylvatica'' is the most commonly cultivated species, yielding a utility timber used for furniture construction, flooring and engineering purposes, in plywood, and household items. The timber can be used to build homes. Beechwood makes excellent firewood. Slats of washed beech wood are spread around ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spruce
A spruce is a tree of the genus ''Picea'' ( ), a genus of about 40 species of coniferous evergreen trees in the family Pinaceae, found in the northern temperate and boreal ecosystem, boreal (taiga) regions of the Northern hemisphere. ''Picea'' is the sole genus in the subfamily Piceoideae. Spruces are large trees, from about 20 to 60 m (about 60–200 ft) tall when mature, and have Whorl (botany), whorled branches and cone (geometry), conical form. Spruces can be distinguished from other Genus, genera of the family Pinaceae by their pine needle, needles (leaves), which are four-sided and attached singly to small persistent peg-like structures (pulvini or sterigmata) on the branches, and by their seed cone, cones (without any protruding bracts), which hang downwards after they are pollinated. The needles are shed when 4–10 years old, leaving the branches rough with the retained pegs. In other similar genera, the branches are fairly smooth. Spruce are used as food pla ...

Hornbeam
Hornbeams are hardwood trees in the plant genus ''Carpinus'' in the family Betulaceae. Its species occur across much of the temperateness, temperate regions of the Northern Hemisphere. Common names The common English name ''hornbeam'' derives from the hardness of the woods (likened to Horn (anatomy), horn) and the Old English ''beam'', "tree" (cognate with Dutch ''Boom'' and German ''Baum''). The American hornbeam is also occasionally known as blue-beech, ironwood, or musclewood, the first from the resemblance of the bark to that of the American beech ''Fagus grandifolia'', the other two from the hardness of the wood and the muscled appearance of the trunk and limbs. The botanical name for the genus, ''Carpinus'', is the original Latin name for the European species, although some etymologists derive it from the Celtic for a yoke. Description Hornbeams are small, slow-growing, understory trees with a natural, rounded form growing tall and wide; the exemplar species—the ...
