Salpausselkä
Salpausselkä (; "Bar Ridge") is an extensive ridge system left by the ice age in Southern Finland. It is a large terminal moraine formation that formed in front of the Baltic ice lake during the Younger Dryas period about 12,250–10,400 years ago. All together the formation is close to from end to end, and the ridges can be as tall as in some places. It runs from Hanko hundreds of kilometers to the east. It traps the extensive river and lake systems of Central Finland known as Finnish Lakeland (, "Lake Finland") and forces the water to flow through few breaches in the ridge. The Vuoksi River flows from lake Saimaa into Lake Ladoga () in Russia. From there the water subsequently flows through river Neva into the Gulf of Finland, bypassing the Salpausselkä. The Kymi River flows from Päijänne into the Gulf of Finland. An artificial breach from the Lakeland is the Saimaa Canal, from Saimaa at Lappeenranta into the Gulf of Finland at Vyborg. Salpausselkä has been used fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Finnish Lakeland
Finnish Lakeland or the Finnish lake district ( , "Lake Finland", ) is a large landscape region in central eastern Finland. The hilly, forest-covered landscape of Lakeland Finland's lake plateau is dominated by drumlins and by long sinuous eskers. Both are glacial remnants deposited after the continental glaciers that scoured and gouged the country's surface receded about 10,000 years ago. The lake basins of the lakeland originate from the joint work of weathering and erosion of fractures in the bedrock. The erosion that made the depressions occurred before and during the Quaternary ice ages. Erosion along fractures has produced linear inlets among the lakes. Demarcation The district occupies most of the central and East Finland and is bounded to the south by the Salpausselkä Ridges. These ridges are terminal moraines, which trap networks of thousands of lakes separated by hilly forested countryside. The lake district turns into the Coastal Finland district to th ...

Lake Ladoga
Lake Ladoga is a freshwater lake located in the Republic of Karelia and Leningrad Oblast in northwestern Russia, in the vicinity of Saint Petersburg. It is the largest lake located entirely in Europe, the second largest lake in Russia after Lake Baikal, and the List of lakes by area, 14th largest freshwater lake by area in the world. It is comparable in size to Lake Ontario. ''Ladoga Lacus'', a methane lake on Saturn's moon Titan (moon), Titan, is named after the lake. Etymology In one of Nestor the Chronicler, Nestor's chronicles from the 12th century a lake called "the Great Nevo" is mentioned, a clear link to the Neva River and possibly further to Finnish language, Finnish ''nevo'' 'sea' or ''neva'' 'bog, quagmire'.:ru:Поспелов, Евгений Михайлович, Evgeny Pospelov: ''Geographical names of the world.

Terminal Moraine
A terminal moraine, also called an end moraine, is a type of moraine that forms at the terminal (edge) of a glacier, marking its maximum advance. At this point, debris that has accumulated by plucking and abrasion, has been pushed by the front edge of the ice, is driven no further and instead is deposited in an unsorted pile of sediment. Because the glacier acts very much like a conveyor belt, the longer it stays in one place, the greater the amount of material that will be deposited. The moraine is left as the marking point of the terminal extent of the ice. Formation As a glacier moves along its path, the surrounding area is continuously eroding. Loose rock and pieces of bedrock are constantly being picked up and transported with the glacier. Fine sediment and particles are also incorporated into the glacial ice. The accumulation of these rocks and sediment together form what is called glacial till when deposited. Push moraines are formed when a glacier retreats from ...

Vuoksi River
The Vuoksi (, historically: "Uzerva"; ; ; ) is a river running through the northernmost part of the Karelian Isthmus from Lake Saimaa in southeastern Finland to Lake Ladoga in northwestern Russia. The river enters Lake Ladoga in three branches, an older main northern branch at Priozersk (Käkisalmi), a smaller branch a few kilometers to the north of it, and a new southern branch entering further southeast as Burnaya River (Finnish: Taipaleenjoki), which has become the main stream in terms of water discharge. Since 1857, the old northern distributaries drain only the lower reaches of the Vuoksi basin and are not fed by Lake Saimaa. The northern and southern branches actually belong to two separate river systems, which at times get isolated from each other in dry seasons. The descent between Lake Saimaa and Lake Ladoga is . The entire run of the river is via the Priozersk branch, or via the Taipale (Burnaya) branch. It has a drainage basin of . For most of its length, the ri ...

Gulf Of Finland
The Gulf of Finland (; ; ; ) is the easternmost arm of the Baltic Sea. It extends between Finland to the north and Estonia to the south, to Saint Petersburg—the second largest city of Russia—to the east, where the river Neva drains into it. Other major cities around the gulf include Helsinki and Tallinn. The eastern parts of the gulf belong to Russia, and some of Russia's most important oil harbors are located there, including Primorsk, Leningrad Oblast, Primorsk. As the seaway to Saint Petersburg, the gulf is of considerable strategic importance to Russia. Some of the Baltic Sea#Environmental status, environmental problems affecting the Baltic Sea are at their most pronounced in the shallow gulf.

Landforms Of Finland
A landform is a land feature on the solid surface of the Earth or other planetary body. They may be natural or may be anthropogenic (caused or influenced by human activity). Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great oceanic basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type. Gross physical features or landforms include intuitive elements such as berms, cliffs, hills, mounds, peninsulas, ridges, rivers, valleys, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodi ...

Glacial Deposits Of Finland
A glacier (; or ) is a persistent body of dense ice, a form of rock, that is constantly moving downhill under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land“Glacier, N., Pronunciation.” Oxford English Dictionary, Oxford UP, June 2024, https://doi.org/10.1093/OED/7553486115.

Central Swedish Ice-edge Zone
The central Swedish ice-edge zone was formed when the melting of ice sheet, inland ice slowed during a cold period approximately 12,000 years ago and the ice edge stood relatively still for around 800 years. This occurred during the Younger Dryas period. The two main terminal moraines of this zone are the Skövde and Billigen ones. These two terminal moraines form parallel and semicontinuous ridges spanning from the Västergötland, Västgöta plains though the Östergötland, Östgöta plains to the Stockholm archipelago.

Groundwater
Groundwater is the water present beneath Earth's surface in rock and Pore space in soil, soil pore spaces and in the fractures of stratum, rock formations. About 30 percent of all readily available fresh water in the world is groundwater. A unit of rock or an unconsolidated deposit is called an ''aquifer'' when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the ''water table''. Groundwater is Groundwater recharge, recharged from the surface; it may discharge from the surface naturally at spring (hydrosphere), springs and Seep (hydrology), seeps, and can form oasis, oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction water well, wells. The study of the distribution and movement of groundwater is ''hydrogeology'', also called groundwater hydrology. Typically, groundwater is thought o ...

Vyborg
Vyborg (; , ; , ; , ) is a town and the administrative center of Vyborgsky District in Leningrad Oblast, Russia. It lies on the Karelian Isthmus near the head of Vyborg Bay, northwest of St. Petersburg, east of the Finnish capital Helsinki, and south of Russia's border with Finland, where the Saimaa Canal enters the Gulf of Finland. The most recent census population of Vyborg is Vyborg was founded as a medieval fortress in Finland under Swedish rule during the Third Swedish Crusade. After numerous wars between the Russians and Swedes, the Treaty of Nöteborg in 1323 defined the border of eastern Finland, and would separate the two cultures. Vyborg remained under Swedish rule until it was captured by the Russians during the Great Northern War. Under Russian rule, Vyborg was the seat of Vyborg Governorate until it was incorporated into the newly established Grand Duchy of Finland, an autonomous part of the Russian Empire. Finland declared its independence from R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
