Okhotsk
Okhotsk ( rus, Охотск, p=ɐˈxotsk) is an urban locality (a work settlement) and the administrative center of Okhotsky District of Khabarovsk Krai, Russia, located at the mouth of the Okhota River on the Sea of Okhotsk. Population: Etymology It was named after the Okhota River, whose name is a corrupted Evenk word ''okat'', "river". History Okhotsk was the main Russian base on the Pacific coast from about 1650 to 1860, but lost its importance after the Amur Annexation in 1860. It is located at the east end of the Siberian River Routes on the Sea of Okhotsk where the Okhota and Kukhtuy rivers join to form a poor-but-usable harbor.

Aldan Highlands
The Aldan Highlands, or Aldan Plateau (; ) are a mountainous area in the Sakha Republic, Far Eastern Federal District, Russia. Aldan town and Tommot are located in the northern area of the highlands and Chulman in the south.Google Earth The Olyokma Nature Reserve is a protected area located on the northwestern side, partly within the neighboring Lena Plateau. History The area of the Aldan and the Yudoma-Maya highlands, between the basins of the Aldan River and the Yudoma, was uncharted territory well until the 1930s. It was first surveyed in 1934 by geologist Yuri Bilibin (1901—1952) together with mining engineer Evgeny Bobin (1897—1941) in the course of an expedition sent by the government of the USSR. Bilibin and Bobin made a thorough topographic survey of the mountainous region leading separate research parties.

Lena Plateau
The Lena Plateau, also known as Prilensky Plateau (; ), is one of the great plateaus of Siberia. Administratively it is mostly within the Sakha Republic (Yakutia), with a small sector in the Irkutsk Oblast, Far Eastern Federal District, Russia. The plateau is named after the Lena River, which flows across it.Google Earth Protected areas There are spectacularly eroded rock formations composed of gypsum-bearing and saline limestone, dolomite and, in some places sandstone, in different spots of the plateau. The Lena Pillars, lining the banks of river Lena in the region, are the most well-known of these features. They were declared a UNESCO World Heritage Site in 2012. Other protected areas in the plateau are the Sinyyaya Pillars by river Sinyaya River (Lena), Sinyaya, and the Turuuk Khaya Rocks by the Lyutenge River. The Olyokma Nature Reserve is located on the eastern side, partly within neighboring Aldan Highlands. Geography The Lena Plateau is located in the southern Sakha Republ ...

Evenki Languages
The Tungusic languages (also known as Manchu–Tungus and Tungus) form a language family spoken in Eastern Siberia and Manchuria by Tungusic peoples. Many Tungusic languages are endangered. There are approximately 75,000 native speakers of the dozen living languages of the Tungusic language family. The term "Tungusic" is from an exonym for the Evenk people (Ewenki) used by the Yakuts ("tongus"). Classification Linguists working on Tungusic have proposed a number of different classifications based on different criteria, including morphological, lexical, and phonological characteristics. Some scholars have criticized the tree-based model of Tungusic classification and argue that the long history of contact among the Tungusic languages makes them better treated as a dialect continuum. The main classification is into a northern branch and a southern branch (Georg 2004) although the two branches have no clear division, and the classification of intermediate groups is debatable.

Hydronym
A hydronym (from , , "water" and , , "name") is a type of toponym that designates a proper name of a body of water. Hydronyms include the proper names of rivers and streams, lakes and ponds, swamps and marshes, seas and oceans. As a subset of toponymy, a distinctive discipline of ''hydronymy'' (or ''hydronomastics'') studies the proper names of all bodies of water, the origins and meanings of those names, and their development and transmission through history. Classification by water types Within the onomastic classification, main types of hydronyms are (in alphabetical order): * helonyms: proper names of swamps, marshes and bogs * limnonyms: proper names of lakes and ponds * oceanonyms: proper names of oceans * pelagonyms: proper names of seas and maritime bays * potamonyms: proper names of rivers and streams Linguistic phenomena Often, a given body of water will have several entirely different names given to it by different peoples living along its shores.

Fossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Though the fossil record is incomplete, numerous studies have demonstrated that there is enough information available to give a good understanding of the pattern of diversification of life on Earth. In addition, the record can predict and fill gaps such as the discovery of '' Tiktaalik'' in the arctic of Canada. Paleontology includes the study of fossils: their age, method of formation, and evolutionary significance. Specimens are sometimes considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years to 4.1 billion years old. Early edition, published online before prin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cambrian
The Cambrian ( ) is the first geological period of the Paleozoic Era, and the Phanerozoic Eon. The Cambrian lasted 51.95 million years from the end of the preceding Ediacaran period 538.8 Ma (million years ago) to the beginning of the Ordovician Period 486.85 Ma. Most of the continents lay in the southern hemisphere surrounded by the vast Panthalassa Ocean. The assembly of Gondwana during the Ediacaran and early Cambrian led to the development of new convergent plate boundaries and continental-margin arc magmatism along its margins that helped drive up global temperatures. Laurentia lay across the equator, separated from Gondwana by the opening Iapetus Ocean. The Cambrian marked a profound change in life on Earth; prior to the Period, the majority of living organisms were small, unicellular and poorly preserved. Complex, multicellular organisms gradually became more common during the Ediacaran, but it was not until the Cambrian that fossil diversity seems to rapidly ...

Drainage Basin
A drainage basin is an area of land in which all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the drainage divide, made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, " watershed" is used only in its original sense, that of the drainage divide line. A drainage basin's boundaries are determined by watershed delineation, a common task in environmental engineering and science. In a closed drainage basin, or endorheic basin, rather than flowing to the ocean, water converges toward the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
