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: a depression created by wind erosion typically in either a partially vegetated 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: an endorheic depression generally containing a persistent or intermittent (seasonal) lake, a 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: Relief, Processus, Environnement,'' Vol. 24, No. 2.

Nenets Autonomous Okrug
The Nenets Autonomous Okrug (russian: Не́нецкий автоно́мный о́круг; Nenets: Ненёцие автономной ӈокрук, ''Nenjocije awtonomnoj ŋokruk'') 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 ...

Pay-Khoy Ridge
The Pay-Khoy Range ( rus, хребет Пай-Хой) 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, to the north of the tree line. Geology The Pay-Khoy range forms a curved orogen together with the Ural Mountains, Vaygach Island and the Novaya Zemlya Novaya Zemlya (, also , ; rus, Но́вая Земля́, p=ˈnovəjə zʲɪmˈlʲa, ...

Quaternary
The Quaternary ( ) is the current and most recent of the three period (geology), periods of the Cenozoic era (geology), Era in the geologic time scale of the International Commission on Stratigraphy (ICS). 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, although a third epoch, the Anthropocene, has been proposed but is not yet officially recognised by the ICS). The Quaternary Period is typically defined by 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 (geologist), Giovanni Arduino proposed that the geological strata of northern Italy could be divided into four successive formations or "orders" ( it, quattro ord ...

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. Deposition 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 has 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 n ...
