Kisten Ridge
Kisten Ridge — one of the mountain ranges of the Greater Caucasus (separated from the main ridge at Mount Barbalo), located in the northeastern part of it, along the left bank of the Andy Koisu River. It forms the watershed of the basin of this river with the rivers of the Sunzha River basin (generally speaking, the Terek-Sulak watershed). From the slopes of the river flow Aksay, Aktash. The length of the ridge is approximately 60 km, the maximum height is 2736 m. It is composed mainly of limestone of the Cretaceous period. Mountain meadow landscapes are widespread on tops, mountain-forest landscapes on northern slopes, and bush-steppe shrubs on southern ones (much steeper). Along the ridge passes the border between Chechnya and Dagestan in their mountainous part. References External links * Андийский хребет // Большая советская энциклопедия : 30 т.nbsp;/ гл. ред. А. М.

Greater Caucasus
The Greater Caucasus ( az, Böyük Qafqaz, Бөјүк Гафгаз, بيوک قافقاز; ka, დიდი კავკასიონი, ''Didi K’avk’asioni''; russian: Большой Кавказ, ''Bolshoy Kavkaz'', sometimes translated as "''Caucasus Major''", "''Big Caucasus''" or "''Large Caucasus''") is the major mountain range of the Caucasus Mountains. The range stretches for about from west-northwest to east-southeast, between the Taman Peninsula of the Black Sea to the Absheron Peninsula of the Caspian Sea: from the Western Caucasus in the vicinity of Sochi on the northeastern shore of the Black Sea and reaching nearly to Baku on the Caspian. Geography The range is traditionally separated into three parts: * The Western Caucasus, between the Black Sea and Mount Elbrus * The Central Caucasus, between Mount Elbrus and Mount Kazbek * The Eastern Caucasus, between Mount Kazbek and the Caspian Sea In the wetter Western Caucasus, the mountains are heavily forest ...

Sunzha River
The Sunzha ( rus, Су́нжа, p=ˈsunʐə, inh, Шолжа, Sholʒə, ce, Соьлжа, Sölƶa, p=sɥølʒə) is a river in North Ossetia, Ingushetia and Chechnya, Russia, a tributary of the Terek. It flows northeast inside the great northwest bend of the Terek River and catches most of the rivers that flow north from the mountains before they reach the Terek. It is long, and has a drainage basin of . The Sunzha rises on the Northern slope of the Caucasus Major. Its major tributaries are the Assa and Argun. With a turbidity of , it carries 12.2 million tons of alluvium per year. It is used for irrigation. Cities that lie on the Sunzha include Nazran, Karabulak, Grozny (the capital of Chechnya), and Gudermes. During the First and Second Chechen Wars, the destruction of petroleum reservoirs caused the Sunzha to become polluted with petroleum. Nomenclature The origin of the name of the river is disputed. The most probable of versions name Sunzha has come from Mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals 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, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now- extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth b ...

Mountain Ranges Of Russia
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...
