Taiga
Taiga or tayga ( ; , ), also known as boreal forest or snow forest, is a biome characterized by coniferous forests consisting mostly of pines, spruces, and larches. The taiga, or boreal forest, is the world's largest land biome. In North America, it covers most of inland Canada, Alaska, and parts of the northern contiguous United States. In Eurasia, it covers most of Sweden, Finland, much of Russia from Karelia in the west to the Pacific Ocean (including much of Siberia), much of Norway and Estonia, some of the Scottish Highlands, some lowland/coastal areas of Iceland, and areas of northern Kazakhstan, northern Mongolia, and northern Japan (on the island of Hokkaido). The principal tree species, depending on the length of the growing season and summer temperatures, vary across the world. The taiga of North America is mostly spruce; Scandinavian and Finnish taiga consists of a mix of spruce, pines and birch; Russian taiga has spruces, pines and larches depending on the reg ...

Larch
Larches are deciduous conifers in the genus ''Larix'', of the family Pinaceae (subfamily Laricoideae). Growing from tall, they are native to the cooler regions of the northern hemisphere, where they are found in lowland forests in the high latitudes, and high in mountains further south. Larches are among the dominant plants in the boreal forests of Siberia and Canada. Although they are conifers, larches are deciduous trees that lose their needles in the autumn. Description and distribution The tallest species, '' Larix occidentalis'', can reach . Larch tree crowns are sparse, with the major branches horizontal; the second and third order branchlets are also ± horizontal in some species (e.g. '' L. gmelinii'', '' L. kaempferi''), or characteristically pendulous in some other species (e.g. '' L. decidua'', '' L. griffithii''). Larch shoots are dimorphic, with leaves borne singly on long shoots typically long and bearing several buds, and in dense clusters of 20–50 need ...

Ecoregion
An ecoregion (ecological region) is an ecological and geographic area that exists on multiple different levels, defined by type, quality, and quantity of environmental resources. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Ecoregions are also known as "ecozones" ("ecological zones"), although that term may also refer to biogeographic realms. Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic fram ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Siberian Taiga
The East Siberian taiga ecoregion, in the taiga and boreal forests biome, is a very large biogeographic region in eastern Russia. Setting This vast ecoregion is located in the heart of Siberia, stretching over 20° of latitude and 50° of longitude (52° to 72° N, and 80° to 130° E). The climate in the East Siberian taiga is subarctic (the trees growing there are coniferous and deciduous) and displays high continentality, with extremes ranging from to and possibly lower. Winters are long and very cold, but dry, with little snowfall due to the effects of the Siberian anticyclone. Summers are short, but can be quite warm for the northerly location. Precipitation is low, ranging from , decreasing from east to west. The topography of this ecoregion is varied, consisting of wide, flat plains and areas of karst topography. In contrast to the neighbouring West Siberian taiga, large bogs and wetlands are conspicuously absent. Some trees also shed their leaves annually, a characteri ...

Trap Rock
Trap rock, also known as either trapp or trap, is any dark-colored, fine-grained, non-granitic intrusive or extrusive igneous rock. Types of trap rock include basalt, peridotite, diabase, and gabbro.Neuendorf, K.K.E., J.P. Mehl, Jr., and J.A. Jackson, J.A., eds. (2005) ''Glossary of Geology'' (5th ed.) American Geological Institute, Alexandria, Virginia. 779 pp. Trap is also used to refer to flood (plateau) basalts, such as the Deccan Traps and Siberian Traps.Le Maitre, R. W., ed. (2002) ''Igneous Rocks: A Classification and Glossary of Terminology''. Cambridge University Press, New York. 236 pp. The erosion of trap rock created by the stacking of successive lava flows often creates a distinct stairstep landscape from which the term ''trap'' was derived from the Swedish word , which means "stairs". The slow cooling of magma either as a sill or as a thick lava flow sometimes creates systematic vertical fractures within the resulting layer of trap rock. These fractures of ...

Volcanic Rock
Volcanic rocks (often shortened to volcanics in scientific contexts) are rocks formed from lava erupted from a volcano. Like all rock types, the concept of volcanic rock is artificial, and in nature volcanic rocks grade into hypabyssal and metamorphic rocks and constitute an important element of some sediments and sedimentary rocks. For these reasons, in geology, volcanics and shallow hypabyssal rocks are not always treated as distinct. In the context of Precambrian shield geology, the term "volcanic" is often applied to what are strictly metavolcanic rocks. Volcanic rocks and sediment that form from magma erupted into the air are called "pyroclastics," and these are also technically sedimentary rocks. Volcanic rocks are among the most common rock types on Earth's surface, particularly in the oceans. On land, they are very common at plate boundaries and in flood basalt provinces. It has been estimated that volcanic rocks cover about 8% of the Earth's current land surface. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sedimentary Rock
Sedimentary rocks are types of rock (geology), rock formed by the cementation (geology), cementation of sediments—i.e. particles made of minerals (geological detritus) or organic matter (biological detritus)—that have been accumulated or deposited at Earth's surface. Sedimentation is any process that causes these particles to settle in place. Geological detritus originates from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or Mass wasting, mass movement, which are called agents of denudation. Biological detritus is formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies (marine snow). Sedimentation may also occur when dissolved minerals precipitate from aqueous solution, water solution. The sedimentary rock cover of ...

Lower Tunguska River
The Nizhnyaya Tunguska ( rus, Ни́жняя Тунгу́ска, p=ˈnʲiʐnʲɪjə tʊnˈɡuskə, meaning "Lower Tunguska") is a river in Siberia, Russia, that flows through the Irkutsk Oblast and the Krasnoyarsk Krai. The river is a right tributary of the Yenisey joining it at Turukhansk (see Siberian River Routes). The ice-free period on the Nizhnyaya Tunguska starts in mid-June and ends in the first half of October. The river forms the western limit of the Lena Plateau. Hydrography The Nizhnyaya Tunguska is the second largest right tributary of the Yenisey, and joins it near the town of Turukhansk. It is long, and has a drainage basin of . According to the character of the stream, constitution of the river's valley and its shores, it can be divided into two parts: the first one starts at the source of the river and continues down to the village (formerly Preobrazhenskoye) and the second section of the river lies downstream of this village in a canyon-like relief.

Bakhta River
The Bakhta () is a river in Krasnoyarsk Krai, Russia. It is a right hand tributary of the Yenisey. The Bakhta is long, and the area of its basin is . The lower reaches of the river are navigable. Course The Bakhta has its source in the Tunguska Plateau, part of the western side of the Central Siberian Plateau. It begins flowing northwestwards, then it bends about midway through its course and flows roughly southwestwards.Бахта, Great Soviet Encyclopedia in 30 vols. / Ch. ed. A.M. Prokhorov . - 3rd ed. - M, 1969-1978. The Bakhta flows in a remote mountainous area through a narrow valley surrounded by taiga until it leaves the plateau area and flows across the Yenisei plain. The Bakhta joins the right bank of the Yenisey at Bakhta village. The confluence is located roughly halfway between the mouths of the Podkamennaya Tunguska and Nizhnyaya Tunguska.Google Earth The river freezes in mid-October and stays frozen until mid-May.
