Lena (river)
The Lena (russian: Ле́на, ; evn, Елюенэ, ''Eljune''; sah, Өлүөнэ, ''Ölüöne''; bua, Зүлхэ, ''Zülkhe''; mn, Зүлгэ, ''Zülge'') is the easternmost of the three great Siberian rivers that flow into the Arctic Ocean (the other two being the Ob and the Yenisey). Permafrost underlies most of the catchment, 77% of which is continuous. It is long, and has a drainage basin of . The Lena is the eleventh-longest river in the world, and the longest river entirely within Russia. Course Originating at an elevation of at its source in the Baikal Mountains south of the Central Siberian Plateau, west of Lake Baikal, the Lena flows northeast across the Lena-Angara Plateau, being joined by the Kirenga, Vitim and Olyokma. From Yakutsk it enters the Central Yakutian Lowland and flows north until joined by its right-hand tributary the Aldan and its most important left-hand tributary, the Vilyuy. After that, it bends westward and northward, flowing between the K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Rivers Of Russia
Russia can be divided into a European and an Asian part. The dividing line is generally considered to be the Ural Mountains. The European part is drained into the Arctic Ocean, Baltic Sea, Black Sea, and Caspian Sea. The Asian part is drained into the Arctic Ocean and the Pacific Ocean. Notable rivers of Russia in Europe are Volga (which is the longest river in Europe), Pechora, Don, Kama, Oka and the Northern Dvina, while several other rivers originate in Russia but flow into other countries, such as the Dnieper and the Western Dvina. In Asia, important rivers are the Ob, the Irtysh, the Yenisei, the Angara, the Lena, the Amur, the Yana, the Indigirka, and the Kolyma. In the list below, the rivers are grouped by the seas or oceans into which they flow. Rivers that flow into other rivers are ordered by the proximity of their point of confluence to the mouth of the main river, i.e., the lower in the list, the more upstream. There is an alphabetical list of rivers at the end of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Verkhoyansk Range
The Verkhoyansk Range (russian: Верхоянский хребет, ''Verkhojanskiy Khrebet''; sah, Үөһээ Дьааҥы сис хайата, ''Üöhee Chaangy sis khaĭata'') is a mountain range in the Sakha Republic, Russia near the settlement of Verkhoyansk, well-known for its frigid climate. It is part of the East Siberian Mountains. The range lies just west of the boundary of the Eurasian and the North American tectonic plates. The mountains were formed by folding, and represent an anticline. The Verkhoyansk Range was covered by glaciers during the Last Glacial Period and the mountains in the northern section, such as the Orulgan Range, display a typical Alpine relief. There are coal, silver, lead, tin and zinc deposits in the mountains. Geography Rising from the shores of the Buor-Khaya Gulf in the north, it runs southwards spanning roughly 1000 km (600 mi.) across Yakutia, east of the Central Yakutian Lowland, and west of the Chersky Range, reaching the ...

Ice Field
An ice field (also spelled icefield) is a mass of interconnected valley glaciers (also called mountain glaciers or alpine glaciers) on a mountain mass with protruding rock ridges or summits. They are often found in the colder climates and higher altitudes of the world where there is sufficient precipitation for them to form. The higher peaks of the underlying mountain rock that protrude through the icefields are known as nunataks. Ice fields are larger than alpine glaciers, but smaller than ice caps and ice sheets. The topography of ice fields is determined by the shape of the surrounding landforms, while ice caps have their own forms overriding underlying shapes. Formation Ice fields are formed by a large accumulation of snow which, through years of compression and freezing, turns into ice. Due to ice's susceptibility to gravity, ice fields usually form over large areas that are basins or atop plateaus, thus allowing a continuum of ice to form over the landscape uninterrupted b ...

Larix Gmelinii
''Larix gmelinii'', the Dahurian larch or Gmelin larch, is a species of larch native to eastern Siberia and adjacent northeastern Mongolia, northeastern China (Heilongjiang), South Korea and North Korea. Description ''Larix gmelinii'' is a medium-sized deciduous Pinophyta, coniferous tree reaching 10–30 m tall, rarely 40 m, with a trunk up to 1 m diameter. The crown is broad conic; both the main branches and the side branches are level, the side branches only rarely drooping. The shoots are dimorphic, with growth divided into long shoots (typically 5–30 cm long) and bearing several buds, and short shoots only 1–2 mm long with only a single bud. The leaf, leaves are needle-like, light green, 2–3 cm long; they turn bright yellow to orange before they fall in the autumn, leaving the variably downy reddish-brown shoots bare until the next spring. The conifer cone, cones are erect, ovoid, 1–2 cm (rarely 2.5 cm) long, with 15–25 moderately reflex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subalpine
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in ...

Mountain Tundra
Alpine tundra is a type of natural region or biome that does not contain trees because it is at high elevation, with an associated harsh climate. As the latitude of a location approaches the poles, the threshold elevation for alpine tundra gets lower until it reaches sea level, and alpine tundra merges with polar tundra. The high elevation causes an adverse climate, which is too cold and windy to support tree growth. Alpine tundra transitions to sub-alpine forests below the tree line; stunted forests occurring at the forest-tundra ecotone are known as ''Krummholz''. With increasing elevation it ends at the snow line where snow and ice persist through summer. Alpine tundra occurs in mountains worldwide. The flora of the alpine tundra is characterized by dwarf shrubs close to the ground. The cold climate of the alpine tundra is caused by adiabatic cooling of air, and is similar to polar climate. Geography Alpine tundra occurs at high enough altitude at any latitude. Portions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Yakutian Lowland
The Central Yakutian LowlandJohn Kimble (ed.), ''Cryosols: Permafrost-Affected Soils'' or Central Yakutian Lowlands (russian: Центральноякутская равнина; sah, Саха сирин ортоку намтала), also known as Central Yakut Plain or Vilyuy Lowland, is a low alluvial plain in Siberia, Russia. Administratively the territory of the lowland is part of the Sakha Republic (Yakutia). It is an extensive plain located in the transition zone between Central and Eastern Siberia and is one of the Great Russian Regions. The main city is Yakutsk, with a number of settlements near it, but the area of the lowland is largely uninhabited elsewhere. Google Earth Geography The Central Yakutian Lowlands extend along the middle basin of the Lena River and partly further downstream and are about in length and wide. They drop gradually from the Central Siberian Plateau to the west and the Lena Plateau to the south and southwest. To the northwest the lowland me ...

Rapids
Rapids are sections of a river where the river bed has a relatively steep gradient, causing an increase in water velocity and turbulence. Rapids are hydrological features between a ''run'' (a smoothly flowing part of a stream) and a ''cascade''. Rapids are characterized by the river becoming shallower with some rocks exposed above the flow surface. As flowing water splashes over and around the rocks, air bubbles become mixed in with it and portions of the surface acquire a white color, forming what is called "whitewater". Rapids occur where the bed material is highly resistant to the erosive power of the stream in comparison with the bed downstream of the rapids. Very young streams flowing across solid rock may be rapids for much of their length. Rapids cause water aeration of the stream or river, resulting in better water quality. Rapids are categorized in classes, generally running from I to VI. A Class 5 rapid may be categorized as Class 5.1-5.9. While Class I rapids are eas ...
