Riss Glaciation
The Riss glaciation, Riss Glaciation, Riss ice age, Riss Ice Age, Riss glacial or Riss Glacial (german: Riß-Kaltzeit, ', ' or (obsolete) ') is the second youngest glaciation of the Pleistocene epoch in the traditional, quadripartite glacial classification of the Alps. The literature variously dates it to between about 300,000 to 130,000 years ago and 347,000 to 128,000 years ago. It coincides with the glaciation of North Germany. The name goes back to and who named this cold period after the river in Upper Swabia in their three-volume work ' ("The Alps in the Ice Age") published between 1901 and 1909. Boundaries and division The Riss glaciation was defined by Penck and Brückner as the Lower (''Niedere'') or Younger Old Moraines and Old Terminal Moraines High Terraces (''Jüngere Altmoränen und Alt-Endmoränen-Hochterrassen''). The type locality lies near Biberach an der Riß where the end of the northeastern Rhine Glacier stood. Results gained from over a century of res ...

Map Of Alpine Glaciations
A map is a symbolic depiction emphasizing relationships between elements of some space, such as objects, regions, or themes. Many maps are static, fixed to paper or some other durable medium, while others are dynamic or interactive. Although most commonly used to depict geography, maps may represent any space, real or fictional, without regard to context or scale, such as in brain mapping, DNA mapping, or computer network topology mapping. The space being mapped may be two dimensional, such as the surface of the earth, three dimensional, such as the interior of the earth, or even more abstract spaces of any dimension, such as arise in modeling phenomena having many independent variables. Although the earliest maps known are of the heavens, geographic maps of territory have a very long tradition and exist from ancient times. The word "map" comes from the , wherein ''mappa'' meant 'napkin' or 'cloth' and ''mundi'' 'the world'. Thus, "map" became a shortened term referring to ...

Lorraine E
Lorraine , also , , ; Lorrain: ''Louréne''; Lorraine Franconian: ''Lottringe''; german: Lothringen ; lb, Loutrengen; nl, Lotharingen is a cultural and historical region in Northeastern France, now located in the administrative region of Grand Est. Its name stems from the medieval kingdom of Lotharingia, which in turn was named after either Emperor Lothair I or King Lothair II. Lorraine later was ruled as the Duchy of Lorraine before the Kingdom of France annexed it in 1766. From 1982 until January 2016, Lorraine was an administrative region of France. In 2016, under a reorganisation, it became part of the new region Grand Est. As a region in modern France, Lorraine consisted of the four departments Meurthe-et-Moselle, Meuse, Moselle and Vosges (from a historical point of view the Haute-Marne department is located in the region), containing 2,337 communes. Metz is the regional prefecture. The largest metropolitan area of Lorraine is Nancy, which had developed for centuries a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erosion (geology)
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical erosion pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Locality (geology)
Type locality, also called type area, is the locality where a particular rock type, stratigraphic unit or mineral species is first identified. If the stratigraphic unit in a locality is layered, it is called a stratotype, whereas the standard of reference for unlayered rocks is the type locality. The term is similar to the term type site in archaeology or the term type specimen in biology. Examples of geological type localities Rocks and minerals * Aragonite: Molina de Aragón, Guadalajara, Spain * Autunite: Autun, France * Benmoreite: Ben More (Mull), Scotland * Blairmorite: Blairmore, Alberta, Canada * Boninite: Bonin Islands, Japan * Comendite: Comende, San Pietro Island, Sardinia * Cummingtonite: Cummington, Massachusetts * Dunite: Dun Mountain, New Zealand. * Essexite: Essex County, Massachusetts, US * Fayalite: Horta, Fayal Island, Azores, Portugal * Harzburgite: Bad Harzburg, Germany * Icelandite: Thingmuli (Þingmúli), Iceland * Ijolite: Iivaara, ...

Iller Glacier
The Iller (; ancient name Ilargus) is a river of Bavaria and Baden-Württemberg in Germany. It is a right tributary of the Danube, long. It is formed at the confluence of the rivers Breitach, Stillach and Trettach near Oberstdorf in the Allgäu region of the Alps, close to the Austrian border. From there it runs northwards, passing the towns of Sonthofen, Immenstadt, and Kempten. Between Lautrach near Memmingen and Ulm it forms the border between the two German States Bavaria and Baden-Württemberg for about . The river flows into the Danube in the city centre of Ulm. The Iller has a catchment area of . It ranks as the seventh of Bavaria's rivers by water flow, with an average throughput of at Senden, a short distance upstream from the Danube. The power of the river is used for the production of hydroelectricity via eight power stations with a total net capacity of 51 MW (1998). A bicycle route follows the Iller, which is also a popular location for rafting and trekkin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inn Glacier
The Inn Glacier (german: Inn-Gletscher), also called the Inn Valley Glacier (''Inntal-Gletscher''). was the ice age glacier of the Alpine river, the Inn. Originating in the Swiss Upper and Lower Engadine (in the present canton of Graubünden), it flowed through the state of Tyrol in Austria (occupying the present day Inn Valley). On German territory it pushed its ice front far into the Bavarian Alpine Foreland. The Inn Glacier attained its greatest thickness and extent during the Riss glaciation ( Old moraines). The overwhelming part of the landforms seen today in the valley carved by the Inn Glacier date, however, to the last ice age, the Würm glaciation ( Young moraines).

Terminal Moraine
A terminal moraine, also called 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 a previo ...

Glacial Lake
A glacial lake is a body of water with origins from glacier activity. They are formed when a glacier erodes the land and then melts, filling the depression created by the glacier. Formation Near the end of the last glacial period, roughly 10,000 years ago, glaciers began to retreat. A retreating glacier often left behind large deposits of ice in hollows between drumlins or hills. As the ice age ended, these melted to create lakes. This is apparent in the Lake District in Northwestern England where post-glacial sediments are normally between 4 and 6 metres deep. These lakes are often surrounded by drumlins, along with other evidence of the glacier such as moraines, eskers and erosional features such as striations and chatter marks. These lakes are clearly visible in aerial photos of landforms in regions that were glaciated during the last ice age. The formation and characteristics of glacial lakes vary between location and can be classified into glacial erosion lake, i ...

European Early Modern Humans
Early European modern humans (EEMH), or Cro-Magnons, were the first early modern humans (''Homo sapiens'') to settle in Europe, migrating from Western Asia, continuously occupying the continent possibly from as early as 56,800 years ago. They interacted and interbred with the indigenous Neanderthals (''H. neanderthalensis'') of Europe and Western Asia, who went extinct 40,000 to 35,000 years ago; and from 37,000 years ago onwards all EEMH descended from a single founder population which contributes ancestry to present-day Europeans. Early European modern humans (EEMH) produced Upper Palaeolithic cultures, the first major one being the Aurignacian, which was succeeded by the Gravettian by 30,000 years ago. The Gravettian split into the Epi-Gravettian in the east and Solutrean in the west, due to major climate degradation during the Last Glacial Maximum (LGM), peaking 21,000 years ago. As Europe warmed, the Solutrean evolved into the Magdalenian by 20,000 years ago, and these peopl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neanderthal
Neanderthals (, also ''Homo neanderthalensis'' and erroneously ''Homo sapiens neanderthalensis''), also written as Neandertals, are an extinct species or subspecies of archaic humans who lived in Eurasia until about 40,000 years ago. While the "causes of Neanderthal disappearance about 40,000 years ago remain highly contested," demographic factors such as small population size, inbreeding and genetic drift, are considered probable factors. Other scholars have proposed competitive replacement, assimilation into the modern human genome (bred into extinction), great climatic change, disease, or a combination of these factors. It is unclear when the line of Neanderthals split from that of modern humans; studies have produced various intervals ranging from 315,000 to more than 800,000 years ago. The date of divergence of Neanderthals from their ancestor '' H. heidelbergensis'' is also unclear. The oldest potential Neanderthal bones date to 430,000 years ago, but the classification ...
