Depression (geology)
In geology, a depression is a landform sunken or depressed below the surrounding area. Depressions form by various mechanisms. Types Erosion-related: * Blowout (geomorphology), Blowout: a depression created by Aeolian processes, wind erosion typically in either a partially vegetated Dune, sand dune ecosystem or dry soils (such as a post-glacial loess environment). * Glacial valley: a depression carved by erosion by a glacier. * River valley: a depression carved by fluvial erosion by a river. * Area of subsidence caused by the collapse of an underlying structure, such as sinkholes in karst terrain. * Sink (geography), Sink: an endorheic depression generally containing a wikt:persistent, persistent or intermittent (seasonal) lake, a Salt pan (geology), salt flat (playa) or dry lake, or an ephemeral lake. * Panhole: a shallow depression or basin eroded into flat or gently sloping, cohesive rock.Twidale, C.R., and Bourne, J.A., 2018Rock basins (gnammas) revisited.''Géomorphologie: ...

Nenets Autonomous Okrug
The Nenets Autonomous Okrug (; ) also known as Nenetsia ( ) is a federal subject of Russia and an autonomous okrug of Arkhangelsk Oblast. Its administrative center is the town of Naryan-Mar. It has an area of and a population of 42,090 as of the 2010 Census, making it the least populous federal subject. A plan to merge the autonomous okrug with Arkhangelsk Oblast was presented by the governors of both federal subjects on 13 May 2020, with a referendum planned for September, but was met with opposition by locals, leading to the merger process being scrapped completely. Geography The arctic ecology of this area has a number of unique features derived from the extreme temperatures and unique geologic province. Polar bears are found in this locale; in fact, the sub-population found here is a genetically distinct taxon associated with the Barents Sea region. The autonomous okrug has a size of approximately 177,000 km2, more than four times the size of Switzerland o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Extreme North
The Extreme North or the Far North is a large part of Russia located mainly north of the Arctic Circle and boasting enormous mineral and natural resources. Its total area is about , comprising about one-third of Russia's total area. Formally, the regions of the Extreme North comprise the whole of Chukotka Autonomous Okrug, Kamchatka Krai, Magadan Oblast, Murmansk Oblast and Sakha Republic, Sakha, as well as certain parts and cities of Arkhangelsk Oblast, Irkutsk Oblast, Khabarovsk Krai, Komi Republic, Krasnoyarsk Krai, Republic of Karelia, Sakhalin Oblast, Tuva, Tyumen Oblast, as well as all islands of the Arctic Ocean, its seas, the Bering Sea, and the Sea of Okhotsk. Due to the remoteness and the harsh conditions of the area, since the Soviet times people who work there have traditionally been entitled by the Russian government to higher wages and many other Welfare spending, benefits, including earlier retirement age, than workers of other regions.

European Russia
European Russia is the western and most populated part of the Russia, Russian Federation. It is geographically situated in Europe, as opposed to the country's sparsely populated and vastly larger eastern part, Siberia, which is situated in Asia, encompassing the entire North Asia, northern region of the continent. The two parts of Russia are divided by the Ural Mountains and Ural (river), Ural river, bisecting the Eurasia, Eurasian supercontinent. European Russia covers the vast majority of Eastern Europe, and spans roughly 40% of Europe's total landmass, with over 15% of its total population, making Russia the List of European countries by area, largest and List of European countries by population, most populous country in Europe. The region is divided into five Federal districts of Russia, Federal districts. Area and demographics European Russia accounts for about 80% of Russia's total population.

Kara River
The Kara () is a river draining to the Arctic Kara Sea in Russia. It flows through the Pai-Khoi Range in the Polar Ural region, and forms parts of the borders between the Yamalo-Nenets Autonomous Okrug, the Nenets Autonomous Okrug and the Komi Republic. The length of the river, from the confluence of the Malaya and Bolshaya Kara to the mouth in the Baydaratskaya Bay is . Its drainage basin area is . The settlement of Ust-Kara is near the river mouth. The name of the river is derived from Nenets The Nenets (; ), in the past also called 'Samoyeds' or 'Yuraks', are a Samoyedic ethnic group native to Arctic Russia, Russian Far North.

Pay-Khoy Ridge
The Pay-Khoy Range () is a mountain range at the northern end of the Ural Mountains. It lies within the Nenets Autonomous Okrug. Geography The ridge is extended from northwest to southeast. It is located on the Yugorsky Peninsula, in the eastern part of the Nenets Autonomous Okrug. The ridge continues to Vaygach Island, thus separating the Barents Sea and the Kara Sea. The highest point of Pay-Khoy is the mountain of Moreiz (). The range separates the drainage basins of the (west, Barents Sea) and the Kara River (east, Kara Sea). The areas around Pay-Khoy do not have permanent population. The closest permanent settlements are Amderma and Ust-Kara, Nenets Autonomous Okrug The range is located in the tundra In physical geography, a tundra () is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons.

Quaternary
The Quaternary ( ) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS), as well as the current and most recent of the twelve periods of the Phanerozoic eon. It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today); a proposed third epoch, the Anthropocene, was rejected in 2024 by IUGS, the governing body of the ICS. The Quaternary is typically defined by the Quaternary glaciation, the cyclic growth and decay of continental ice sheets related to the Milankovitch cycles and the associated climate and environmental changes that they caused. Research history In 1759 Giovanni Arduino proposed that the geological strata of northern Italy could be divided into four succ ...

Deposit (geology)
Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment. This occurs when the forces responsible for sediment transportation are no longer sufficient to overcome the forces of gravity and friction, creating a resistance to motion; this is known as the null-point hypothesis. Deposition can also refer to the buildup of sediment from organically derived matter or chemical processes. For example, chalk is made up partly of the microscopic calcium carbonate skeletons of marine plankton, the deposition of which induced chemical processes ( diagenesis) to deposit further calcium carbonate. Similarly, the formation of coal begins with the deposition of organic material, mainly from plants, in anaerobic conditions. Null-point hypothesis The null-point ...

Geography Of Russia
Russia () is the largest country in the world, covering over , and encompassing more than one-eighth of Earth's inhabited land area. Russia extends across eleven time zones, and has the most borders of any country in the world, with sixteen sovereign nations. Russia is a transcontinental country, stretching vastly over two continents, Europe and Asia. It spans the northernmost edge of Eurasia, and has the world's fourth-longest coastline, at . Russia, alongside Canada and the United States, is one of only three countries with a coast along three oceans (however connection to the Atlantic Ocean is extremely remote), due to which it has links with over thirteen marginal seas. It lies between latitudes 41° and 82° N, and longitudes 19° E and 169° W. Russia is larger than three continents of the world and has about the same surface area as Pluto. Russia encompasses, by far, the largest forest area of any country in the world. Global position and boundaries Kalining ...
