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.

Hindens Rev
Hindens Rev is a long, narrow, straight peninsula that projects westwards from Kålland into Dalbosjön, the western part of lake Vänern. Hindens rev is a terminal moraine and is part of what is known as the central Swedish terminal moraine zone. The latter is in turn part of a series of terminal moraines that runs from southern Norway through Dalsland, Västra Götaland County, Skaraborg and Östergötland, continuing under the Baltic Sea into southern Finland and Russia as the Salpausselkä moraine which separates lakes Lake Ladoga, Ladoga and Saimaa. These moraines were formed during the Younger Dryas period, about 11,000 years ago, when the ice cap from the last ice age temporarily ceased withdrawing and rocks and other glacial materials emerged from the melting ice were deposited in front of the glacier terminus. The narrow peninsula is about five kilometers long and never wider than 100 meters, usually significantly narrower. Its highest elevation over the level of lake Vän ...

Ice Sheet
In glaciology, an ice sheet, also known as a continental glacier, is a mass of glacier, glacial ice that covers surrounding terrain and is greater than . The only current ice sheets are the Antarctic ice sheet and the Greenland ice sheet. Ice sheets are bigger than ice shelf, ice shelves or alpine glaciers. Masses of ice covering less than 50,000 km2 are termed an ice cap. An ice cap will typically feed a series of glaciers around its periphery. Although the surface is cold, the base of an ice sheet is generally warmer due to Geothermal activity, geothermal heat. In places, melting occurs and the melt-water lubricates the ice sheet so that it flows more rapidly. This process produces fast-flowing channels in the ice sheet — these are ice streams. Even stable ice sheets are continually in motion as the ice gradually flows outward from the central plateau, which is the tallest point of the ice sheet, and towards the margins. The ice sheet slope is low around the plate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Younger Dryas
The Younger Dryas (YD, Greenland Stadial GS-1) was a period in Earth's geologic history that occurred circa 12,900 to 11,700 years Before Present (BP). It is primarily known for the sudden or "abrupt" cooling in the Northern Hemisphere, when the North Atlantic Ocean cooled and annual air temperatures decreased by ~ over North America, in Europe and up to in Greenland, in a few decades. Cooling in Greenland was particularly rapid, taking place over just 3 years or less. At the same time, the Southern Hemisphere experienced warming. This period ended as rapidly as it began, with dramatic warming over ~50 years, the transition from the glacial Pleistocene epoch into the current Holocene. The Younger Dryas onset was not fully synchronized; in the tropics, the cooling was spread out over several centuries, and the same was true of the early-Holocene warming. Even in the Northern Hemisphere, temperature change was highly seasonal, with much colder winters, cooler springs, yet no cha ...

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 ...

Västergötland
Västergötland (), also known as West Gothland or the Latinized version Westrogothia in older literature, is one of the 25 traditional non-administrative provinces of Sweden (''landskap'' in Swedish), situated in the southwest of Sweden. Västergötland is home to Gothenburg, the second largest city in Sweden, which is situated along a short stretch of the Kattegat strait. The province is bordered by Bohuslän, Dalsland, Värmland, Närke, Östergötland, Småland and Halland, as well as the two largest Swedish lakes Vänern and Vättern. Victoria, Crown Princess of Sweden is Duchess of Västergötland. Administration The provinces of Sweden serve no administrative function. Instead, that function is served by counties of Sweden. From the 17th century up until 31 December 1997, Västergötland was divided into Skaraborg County, Älvsborg County and a minor part of Gothenburg and Bohus County. From 1 January 1998 nearly all of the province is in the newly created Väs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Östergötland
Östergötland (; English exonym: East Gothland) is one of the traditional provinces of Sweden (''landskap'' in Swedish) in the south of Sweden. It borders Småland, Västergötland, Närke, Södermanland and the Baltic Sea. In older English literature, the Latinized version ''Ostrogothia'' is also used. The corresponding administrative county, Östergötland County, covers the entire province and parts of neighbouring provinces. Heraldry From 1560, Östergötland was represented with two separate coats-of-arms seals until 1884, when the current one was granted. The coat of arms is represented with a ducal coronet. Blazon: " gules a griffin with dragon wings, tail and tongue rampant or armed, beaked, langued and membered azure between four roses argent." Geography From west to east, in the middle parts, extends the Östgöta Plain (''Östgötaslätten''). It is largely agricultural. In the southern part of the province, the terrain becomes marked by the south Swedish hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stockholm Archipelago
The Stockholm Archipelago () is the largest archipelago in Sweden, and the second-largest archipelago in the Baltic Sea (the largest being the Archipelago Sea across the Baltic in Finland). Part of the archipelago has been designated as a Ramsar site since 1989. Stockholm Archipelago has been found to have slightly over 24,000 islands, islets and skerries and covers approximately 1,700 km² of which approximately 530 km² is land. There are around 10,000 permanent residences and 50,000 holiday homes in the archipelago. Residents are found on all the larger islands closest to the coast that have fixed bridges or ferry connections with road ferries, such as Vaxholm, Ingarö, Värmdö, Yxlan, Blidö, Ljusterö and Väddö, but also on many of the larger islands farther out from the coast, as Ingmarsö, Möja, Runmarö, Nämdö, Ornö and Utö, which are served by passenger ships with fixed itineraries.

Central Swedish Lowland
The Central Swedish lowland () 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. The Central Swedish lowland forms a broad east-west trending belt north of the South Swedish highlands and south of the Norrland terrain. Traditionally the heartland of Sweden due to its large population and agricultural resources the region benefits additionally from the proximity of hydropower, forest and mineral resources. The lowland is also at a good position for trade with the Baltic region. These advantages are reflected in the location of Sweden's capital, Stockholm, at the eastern end of the lowlands. Most of Sweden's manufacturing industries lies in this region. Relief, soil and vegetation The reason on how the lowlands reached its sunken position relative to other parts of Sweden is not clear. Possibly its boundaries are flexures in Earth's crust rather, the possibility of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology Of Sweden
The geology of Sweden is the regional study of rocks, minerals, tectonics, natural resources and groundwater in the country. The oldest rocks in Sweden date to more than 2.5 billion years ago in the Precambrian. Complex orogeny mountain building events and other tectonic occurrences built up extensive metamorphic crystalline basement rock that often contains valuable metal deposits throughout much of the country. Metamorphism continued into the Paleozoic after the Snowball Earth glaciation as the continent Baltica collided with an island arc and then the continent Laurentia. Sedimentary rocks are most common in southern Sweden with thick sequences from the last 250 million years underlying Malmö and older marine sedimentary rocks forming the surface of Gotland. Stratigraphy, Tectonics & Geologic History The oldest rocks in Sweden date to the Archean, more than 2.5 billion years ago. Archean crystalline basement rocks are restricted to a few areas in the far north and are mainly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Glacial Deposits Of Sweden
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 ...
