Salpausselkä Medal
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 for t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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. Accessed 25 Jan. 2025. and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continen ...

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.

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.

Saimaa Canal
The Saimaa Canal (; ; ) is a transportation canal that connects lake Saimaa with the Gulf of Finland near Vyborg, Russia. The canal was built from 1845 to 1856 and opened on 7 September 1856 (Old Style: 26 August 1856). It was overhauled and widened in 1963–1968. A system of inland waterways and canals in the 120 interconnected lakes of the south-central and south-east part of Finland (Finnish Lakeland) are reached through the canal. The network of deep channels in Lake Saimaa with at least a draught of covers . The deep channels extend all the way to Kuopio in Central Finland. The canal is closed in the winter.

Kymi River
The Kymi (, ) is a river in Finland. It begins at Lake Päijänne, flows through the provinces of Päijänne Tavastia, Uusimaa and Kymenlaakso, and discharges into the Gulf of Finland. The river passes the towns of Heinola and Kouvola. The town of Kotka is located on the river delta.

Being one of the largest rivers in Southern Finland, the Kymi is a major source of hydroelectricity. The towns of Kotka, Kuusankoski, Myllykoski and Inkeroinen along the river are major centres of the pulp and paper industry. Formerly the river was extensively used for timber rafting. The Kymi has five mouths. It divides into two main branches near the Kultaankosk ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.
