Salpausselkä Ridges
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 f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Landforms Of Finland
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. 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 ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glacial Deposits Of Finland
A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances. Interglacials, on the other hand, are periods of warmer climate between glacial periods. The Last Glacial Period ended about 15,000 years ago. The Holocene is the current interglacial. A time with no glaciers on Earth is considered a greenhouse climate state. Quaternary Period Within the Quaternary, which started about 2.6 million years before present, there have been a number of glacials and interglacials. At least eight glacial cycles have occurred in the last 740,000 years alone. Penultimate Glacial Period The Penultimate Glacial Period (PGP) is the glacial period that occurred before the Last Glacial Period. It began about 194,000 years ago and ended 135,000 years ago, with the beginning of the Eemian interglacial. Last Glacial Period The last glacial period was the most recent glacial period ...

Central Swedish Ice-edge Zone
The central Swedish ice-edge zone was formed when the melting of 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 Västgöta plains though the Östgöta plains to the Stockholm archipelago. See also *Central Swedish lowland The Central Swedish lowland ( sv, Mellansvenska sänkan, Mellansvenska låglandet) is a large region of low relief and altitude in Sweden spanning from the Swedish West Coast at Bohuslän to Stockholm archipelago and Roslagen at the Baltic Sea.

Groundwater
Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations. About 30 percent of all readily available freshwater 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 recharged from the surface; it may discharge from the surface naturally at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology. Typically, groundwater is thought of as water flowing through shallow aquifers, but, in the technical sense, it can also contain soil moisture, perma ...

Saimaa Canal
The Saimaa Canal ( fi, Saimaan kanava; sv, Saima kanal; russian: Сайменский канал) 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.

Kymi River
The Kymi ( fi, Kymijoki, sv, Kymmene älv) 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. The length of the river is , but its drainage basin of extends to almost inside the Tavastia, Central Finland, Savonia and Ostrobothnia. The furthest source of the river is Lake Pielavesi, its furthest point being some from the sea measured by flow route. The name of the river, itself, ''kymi'', means "large river", in Old Finnish. 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 Kymijoki river has five mouths. It divides in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Of Finland
The Gulf of Finland ( fi, Suomenlahti; et, Soome laht; rus, Фи́нский зали́в, r=Finskiy zaliv, p=ˈfʲinskʲɪj zɐˈlʲif; sv, Finska viken) is the easternmost arm of the Baltic Sea. It extends between Finland to the north and Estonia to the south, to Saint Petersburg in 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 of Finland belong to Russia, and some of Russia's most important oil harbors are located farthest in, near Saint Petersburg (including Primorsk). As the seaway to Saint Petersburg, the Gulf of Finland has been and continues to be of considerable strategic importance to Russia. Some of the environmental problems affecting the Baltic Sea are at their most pronounced in the shallow gulf. Proposals for a tunnel through the gulf have been made. Geography The gulf has an area of . The length (from the Hanko Peninsula to Saint Petersburg) is and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
