As a two -thousand (also written shortly as: 2000s) are called mountains, having a height of at least 2000 meters but less than 3000 meters above sea level.

Deposits in Central Europe

Central Mountains are ( for Central Europe) defined to about 1500 to 1800 m, so that they are there not present in the rule. In the foothills of the high mountains in Europe appreciable 2000s have mostly the character of rocky, geographically dominant mountains. In the high mountains themselves form allfällig only Graterhebungen and streamers, just as hills they can emerge when high levels are below the 2000 mark.

Climatic aspects

Climatically the difference to upland areas is striking, if the 2000 has a wind-exposed location. The temperatures are still around but mostly in the same range, while three thousand meters in the temperate latitudes, even in midsummer, the zero -degree limit can be exceeded.

Bio - geographical aspects and settlement

Considered biogeographically the 2000 Central Europe already are deep in the alpine level (or counterparts in other parts of the world ) and are all above the tree line, settlement geographically in temperate latitudes to the Anökumene: This is not a permanent settlement, and no agriculture possible ( the highest permanent settlements in the Alps to be about 2100 meters), but still in the middle of the alpine region (up to about 2500 m turf and mats, about Subnival cushion plants ). In the Mediterranean area here already is the arid thorn cushion stage (starts in Crete in 1500, in the atlas at 2400 m), the two peaks are of largely wüstenkahlem appearance. In the Andes as it is called in the tropical part of the level from 2000 m ( 3500 m) Tierra Fria ( " cold land"), here are the 2000, which primarily form the coastal and Amazonian damp upstream processes, completely below the tree line ( Nebelwäder in East: Yungas, in the west of Lomas ). In the Hindu Kush, they form the typical coniferous forest stage as foothills and Talumrahmung.

Mountaineering and sporting aspects

Alpininistisch 2000s are generally considered mild to moderately challenging tours of the center and submontane, but then mostly as an attractive prospect mountains. The thinning mountain air begins at 2000 to play a role, at 2500 meters above sea level the air pressure is about only 560 mmHg/750 mbar ( compared with about 760 mmHg/1013 mbar at sea level, or about ¾; Barometric height formula ). This provides for the amount not familiar mountain visitors already a significant burden, on the other hand the positive effect has been demonstrated on the metabolism even at this altitude: 2500 meters, the increase in respiratory ventilation is at the beginning of the acclimatization period, 65% of the body processes are compared with normal increased to three to seven times. Therefore 2000s tours are (avoid overloading provided of course ) already quite favorable to health, and at this altitude - of course not only related to mountain peaks - is also recommended for hypoxia ( altitude training ). Direct ascent aids ( cable car or truck) provides for a healthy body in general is no abnormal load, Acute Mountain Sickness (AMS ) occurs normally until the 3000m mark one, little problems from 2500 m.
