France–Italy Border
The France–Italy border is 515 km (320 mi) long. It runs from the Alps in the north, a region in which it passes over Mont Blanc, down to the Mediterranean coast in the south. Three national parks are located along the border: Vanoise National Park and Mercantour National Park on the French side and Gran Paradiso National Park on the Italian side. Features The France–Italy border is mainly mountainous. It is long, in southeast France and northwest Italy. It begins at the west tripoint of France–Italy–Switzerland () near the top of Mont Dolent ( m), in the French commune of Chamonix (department of Haute-Savoie), the Italian city of Courmayeur (Aosta Valley) and the Swiss commune of Orsières (canton of Valais). The boundary then follows a general direction towards south, to the Mediterranean, it reaches the sea at Menton in France and Ventimiglia in Italy. The border separates three regions (Aosta Valley, Piedmont and Liguria) and four provinces of Italy (Aosta, Turin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpine Three-thousanders
Three-thousanders are mountains with a height of between , but less than above sea level. Similar terms are commonly used for mountains of other height brackets e. g. four-thousanders or eight-thousanders. In Britain, the term refers to mountains above . Climatological significance In temperate latitudes three-thousanders play an important role, because even in summer they lie below the zero degree line for weeks. Thus the chains of three-thousanders always form important climatic divides and support glaciation - in the Alps the contour is roughly the general limit of the "nival step"; only a few glaciated mountains are under (the Dachstein, the easternmost glaciated mountain in the Alps, is, at , not a three-thousander). In the Mediterranean, however, the three-thousanders remain free of ice and, in the tropics, they are almost insignificant from a climatic perspective; here the snow line lies at around to , and in the dry continental areas (Trans-Himalayas, Andes) it ...

Mountains Of Piedmont
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least above the surrounding land. A few mountains are inselberg, isolated summits, but most occur in mountain ranges. mountain formation, Mountains are formed through tectonic plate, tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosystems of mountains: different elevations hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gneiss
Gneiss (pronounced ) is a common and widely distributed type of metamorphic rock. It is formed by high-temperature and high-pressure metamorphic processes acting on formations composed of igneous or sedimentary rocks. This rock is formed under pressures ranging from 2 to 15 kbar, sometimes even more, and temperatures over 300 °C (572 °F). Gneiss nearly always shows a banded texture characterized by alternating darker and lighter colored bands and without a distinct Cleavage (geology), cleavage. Gneisses are common in the ancient crust of Continental Shield, continental shields. Some of the oldest rocks on Earth are gneisses, such as the Acasta Gneiss. Description image:Orthogneiss Geopark.jpg, Orthogneiss from the Czech Republic In traditional English and North American usage, a gneiss is a coarse-grained metamorphic rock showing compositional banding (gneissic banding) but poorly developed schistosity and indistinct Cleavage (geology), cleavage.

Quartz
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The Atom, atoms are linked in a continuous framework of SiO4 silicon–oxygen Tetrahedral molecular geometry, tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of Silicon dioxide, SiO2. Quartz is, therefore, classified structurally as a Silicate mineral#Tectosilicates, framework silicate mineral and compositionally as an oxide mineral. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar. Quartz exists in two forms, the normal α-quartz and the high-temperature β-quartz, both of which are chiral. The transformation from α-quartz to β-quartz takes place abruptly at . Since the transformation is accompanied by a significant change in volume, it can easily induce microfracturing of ceramics or rocks passing through this temperature threshold. There are many different varieties of quartz, several of which are classifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arc (Savoie)
The Arc () is a river in the Savoie département of south-eastern France. It is a left tributary of the Isère, which it joins at Chamousset, approximately downstream from Albertville. Its source is near the border with Italy, in the Graian Alps, northeast of Bonneval-sur-Arc. The valley of the Arc, the Maurienne, is an important transport artery between France and Italy.

Maurienne
Maurienne (; ; ) is one of the provinces of Savoy, corresponding to the arrondissement of Saint-Jean-de-Maurienne in France. It is also the original name of the capital of the province, now Saint-Jean-de-Maurienne. Location The Maurienne valley is one of the great transverse valleys of the Alps. The river which has shaped the valley since the last glaciation is the Arc. The valley begins at the village of Écot (in the '' commune'' of Bonneval-sur-Arc), at the foot of the Col de l'Iseran, and ends at the confluence of the Arc and the Isère in the ''commune'' of Aiton. The mountains on the southern side are the Dauphiné Alps and the Cottian Alps. On the northern side are the part of the Graian Alps known as the Vanoise. The capital, Saint-Jean-de-Maurienne, lies at the confluence of the Arc and the Arvan. Roads and railways Part of the main road and rail route between Lyon and Turin runs through the valley.

Susa Valley
The Susa Valley (; ; ; ; ) is a valley in the Metropolitan City of Turin, Piedmont region of northern Italy, located between the Graian Alps in the north and the Cottian Alps in the south. It is one of the longest valleys of the Italian Alps. It extends over in an east-west direction from the French border to the outskirts of Turin. The valley takes its name from the city of Susa which lies in the valley. The Dora Riparia river, a tributary of the Po, flows through the valley. A motorway runs through the valley from Turin to Chambéry in France through the Fréjus tunnel or by crossing the Col du Mont Cenis (2083m), and to Briançon, also in France, over the Col de Montgenèvre.

Cottian Alps
The Cottian Alps (; ; ) are a mountain range in the southwestern part of the Alps. They form the border between France (Hautes-Alpes and Savoie) and Italy (Piedmont). The Fréjus Road Tunnel and Fréjus Rail Tunnel between Modane and Susa, Italy, Susa are important transportation arteries between France (Lyon, Grenoble) and Italy (Turin). Etymology The name ''Cottian'' comes from ''Cottius, Marcus Julius Cottius'', a king of the tribes inhabiting that mountainous region in the 1st century BC. Under his father Donnus, these tribes had previously opposed but later made peace with Julius Caesar. Cottius was succeeded by his son Gaius Julius Donnus II (reigned 3 BC-4 AD), and his grandson Marcus Julius Cottius II (reigned 5-63 AD), who was granted the title of king by the emperor Claudius. On his death, Nero annexed his kingdom as the Roman province, province of Alpes Cottiae. History For a long part of the Middle Ages the Cottian Alps were divided between the Duchy of Savoy, ...
