Alps
Template:Geobox The Alps (German: Alpen; Italian: Alpi; French: Alpes; Slovene: Alpe) is the name for one of the great mountain range systems of Europe, stretching from Austria and Slovenia in the east, through Italy, Switzerland, Liechtenstein and Germany to France in the west. The word "Alps" was taken via French from Latin Alpes (meaning "the Alps"), which may be influenced by the Latin words albus (white) or altus (high) or more likely a Latin rendering of a Celtic or Ligurian original.
The highest mountain in the Alps is Mont Blanc, at 4,808 metres (15,774 ft), on the French-Italian border. All the main peaks of the Alps can be found in the list of mountains of the Alps and list of Alpine peaks by prominence.
The Alps r kinda funny
Climate
The Alps are a classic example of what happens when a temperate area at lower altitude gives way to higher elevation terrain. Elevations around the world which have cold climates similar to those found in polar areas have been called alpine. A rise from sea level into the upper regions of the atmosphere causes the temperature to decrease. The effect of mountain chains on prevailing winds is to carry warm air belonging to the lower region into an upper zone, where it expands in volume at the cost of a proportionate loss of heat, often accompanied by the precipitation of moisture in the form of snow or rain.
Geology
The Alps arose as a result of the pressure exerted on sediments of the Tethys Ocean basin as its Mesozoic and early Cenozoic strata were pushed against the stable Eurasian landmass by the northward-moving African landmass. Most of this occurred during the Oligocene and Miocene epochs. The pressure formed great recumbent folds, or nappes, that rose out of what had become the Tethys Sea and pushed northward, often breaking and sliding one over the other to form gigantic thrust faults. Crystalline rocks, which are exposed in the higher central regions, are the rocks forming Mont Blanc, the Matterhorn, and high peaks in the Pennine Alps and Hohe Tauern.
The landscape seen today is mostly formed by glaciation during the past two million years. At least five ice ages have done much to change the region, scooping out the lakes and rounding off the limestone hills along the northern border. Glaciers have been retreating during the past 10,000 years, leaving large granite erratics scattered in the forests in the region. As the last ice age ended, it is believed that the climate changed so rapidly that the glaciers retreated back into the mountains in a span of about 200 to 300 years.
Political and cultural history
Little is known of the early dwellers in the Alps, save from the scanty accounts preserved by Roman and Greek historians and geographers. A few details have come down to us of the conquest of many of the Alpine tribes by Augustus.
The successive emigration and occupation of the Alpine region by various Teutonic tribes from the 5th to the 6th centuries are known only in outline, because to them, as to the Frankish kings and emperors, the Alps offered a route to other places rather than a permanent residence.
It is not until the final breakup of the Carolingian Empire in the 10th and 11th centuries that it becomes possible to trace out the local history of the Alps.
Exploration
The higher regions of the Alps were long left to the exclusive attention of the people of the adjoining valleys, even when Alpine travellers (as distinguished from Alpine climbers) began to visit these valleys. The two men who first explored the regions of ice and snow were H.B. de Saussure (1740-1799) in the Pennine Alps, and the Benedictine monk of Disentis, Placidus a Spescha (1752-1833), most of whose ascents were made before 1806, in the valleys at the sources of the Rhine.
Flora
A natural vegetation limit with altitude is given by the presence of the chief deciduous trees — oak, beech, ash and sycamore maple. These do not reach exactly to the same elevation, nor are they often found growing together; but their upper limit corresponds accurately enough to the change from a temperate to a colder climate that is further proved by a change in the wild herbaceous vegetation. This limit usually lies about 1,200 metres (3,940 ft) above the sea on the north side of the Alps, but on the southern slopes it often rises to 1,500 metres (4,920 ft), sometimes even to 1,700 metres (5,580 ft).
This region is not always marked by the presence of the characteristic trees. Human interference has nearly exterminated them in many areas, and, except for the beech forests of the Austrian Alps, forests of deciduous trees are rarely found. In many districts where such woods once existed, they have been replaced by the Scots pine and Norway spruce, which are less sensitive to the ravages of goats, who are the worst enemies of such trees. The mean annual temperature of this region differs little from that of the British Islands; but climatic conditions are widely different. In the Alps, snow usually stays for several months, until spring and summer, which are considerably warmer on average than those seasons in Britain.
Above the forestry, there is often a band of short pine trees (Pinus mugo), which is in turn superseded by dwarf shrubs, typically Rhododendron ferrugineum (on acid soils) or Rhododendron hirsutum (on basic soils). Above this is the alpine meadow, and even higher, the vegetation becomes more and more sparse. At these higher altitudes, the plants tend to form isolated cushions. In the Alps, several species of flowering plants have been recorded above 4,000 metres (13,120 ft), including Ranunculus glacialis, Androsace alpina and Saxifraga biflora.48+3
