Plateau
Plateau (also plateau , high plateau or plateau , in the Spanish-speaking area Meseta , in the Portuguese area Planalto ) describes a flat or slightly hilly landscape or region that is significantly higher than the surrounding area or parts of it.
In the mountains, however , a high plateau can also have height differences of several hundred meters, such as B. in limestone mountains that are undercut by karst processes. Special forms can be found in the highlands of Tibet and in the Andes , where they have altitudes of 4000 or 5000 m.
Meanings of terms
In regions close to the coast , one speaks of a plateau at heights of around 200 m above sea level , if the relief energy on the plateau remains low, so the height differences are insignificant.
In mountainous countries far from the coast , however, plateaus can also be several kilometers above sea level. Such plateaus can extend over several hundred kilometers (such as the highlands of Tibet ) and with a suitable climate can be densely populated up to an altitude of over 3000 m.
In the north German lowlands , the name plate has become established for plateaus that are only a few to a few tens of meters higher than the surrounding area .
Often a plateau is bounded by mountain ranges - see Central Asia and South America - or interrupted by central subsidence areas or sedimentary basins .
The summit region of a ridge can also be referred to as a plateau or high plateau if the term table mountain is not appropriate because of the moderate slope of the slopes .
