A mountain is a large landform that rises above the surrounding land in a limited area in the form of a peak. A mountain is steeper than a hill. Mountains are formed through tectonic forces or volcanism; these forces can locally raise the surface of the earth. Mountains erode through the action of rivers, weather conditions, glaciers. A few mountains are isolated summits. High elevations on mountains produce colder climates than at sea level; these colder climates affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains tend to be used less for agriculture and more for resource extraction and recreation, such as mountain climbing; the highest mountain on Earth is Mount Everest in the Himalayas of Asia, whose summit is 8,850 m above mean sea level. The highest known mountain on any planet in the Solar System is Olympus Mons on Mars at 21,171 m. There is no universally accepted definition of a mountain.
Elevation, relief, steepness and continuity have been used as criteria for defining a mountain. In the Oxford English Dictionary a mountain is defined as "a natural elevation of the earth surface rising more or less abruptly from the surrounding level and attaining an altitude which to the adjacent elevation, is impressive or notable."Whether a landform is called a mountain may depend on local usage. Mount Scott outside Lawton, Oklahoma, USA, is only 251 m from its base to its highest point. Whittow's Dictionary of Physical Geography states "Some authorities regard eminences above 600 metres as mountains, those below being referred to as hills." In the United Kingdom and the Republic of Ireland, a mountain is defined as any summit at least 2,000 feet high, whilst the official UK government's definition of a mountain, for the purposes of access, is a summit of 600 metres or higher. In addition, some definitions include a topographical prominence requirement 100 or 500 feet. At one time the U.
S. Board on Geographic Names defined a mountain as being 1,000 feet or taller, but has abandoned the definition since the 1970s. Any similar landform lower. However, the United States Geological Survey concludes that these terms do not have technical definitions in the US; the UN Environmental Programme's definition of "mountainous environment" includes any of the following: Elevation of at least 2,500 m. Using these definitions, mountains cover 33% of Eurasia, 19% of South America, 24% of North America, 14% of Africa; as a whole, 24% of the Earth's land mass is mountainous. There are three main types of mountains: volcanic and block. All three types are formed from plate tectonics: when portions of the Earth's crust move and dive. Compressional forces, isostatic uplift and intrusion of igneous matter forces surface rock upward, creating a landform higher than the surrounding features; the height of the feature makes it either a hill or, if steeper, a mountain. Major mountains tend to occur in long linear arcs, indicating tectonic plate boundaries and activity.
Volcanoes are formed when a plate is pushed at a mid-ocean ridge or hotspot. At a depth of around 100 km, melting occurs in rock above the slab, forms magma that reaches the surface; when the magma reaches the surface, it builds a volcanic mountain, such as a shield volcano or a stratovolcano. Examples of volcanoes include Mount Pinatubo in the Philippines; the magma does not have to reach the surface in order to create a mountain: magma that solidifies below ground can still form dome mountains, such as Navajo Mountain in the US. Fold mountains occur when two plates collide: shortening occurs along thrust faults and the crust is overthickened. Since the less dense continental crust "floats" on the denser mantle rocks beneath, the weight of any crustal material forced upward to form hills, plateaus or mountains must be balanced by the buoyancy force of a much greater volume forced downward into the mantle, thus the continental crust is much thicker under mountains, compared to lower lying areas.
Rock can fold either asymmetrically. The upfolds are anticlines and the downfolds are synclines: in asymmetric folding there may be recumbent and overturned folds; the Balkan Mountains and the Jura Mountains are examples of fold mountains. Block mountains are caused by faults in the crust: a plane; when rocks on one side of a fault rise relative to the other, it can form a mountain. The uplifted blocks are block horsts; the intervening dropped blocks are termed graben: these can be small or form extensive rift valley systems. This form of landscape can be seen in East Africa, the Vosges, the Basin and Range Province of Western North America and the Rhine valley; these areas occur when the regional stress is extensional and the crust is thinned. During and following uplift, mountains are subjected to the agents of erosion which wear the uplifted area down. Erosion causes the surface of mountains to be younger than the rocks that form the mountains themselves. Glacial processes produce characteristic landforms, such as pyramidal peaks, knife-edge arêtes, bowl-shaped cirques that can contai
The Iberian System, is one of the major systems of mountain ranges in Spain. It consists of a vast and complex area of relatively high and rugged mountain chains and massifs located in the central region of the Iberian Peninsula, but reaching the Mediterranean coast in the Valencian Country in the east. From the hydrographic viewpoint this system is of the highest relevance in the peninsula, for it separates the watersheds of most of the major rivers in Spain and Portugal, including the Ebro basin from the basins of the Douro, Guadiana, Júcar and Turia. There are important mining areas in some of the ranges such as Sierra Menera, Sierra de Arcos and Sierra de San Just, making the system one of the chief mining regions in Spain since ancient times. One of the comarcas of Aragon located in the Iberian System was given the name of Cuencas Mineras since mining is the main activity in the comarca; the Sistema Ibérico mountain range borders the Meseta Central on its western end and separates the Meseta Central from the Ebro valley and from the Mediterranean coast.
This system runs northwest-southeast between the Ebro plain and the Meseta Central for over 500 km, from the La Bureba corridor in Burgos Province close to the Cordillera Cantábrica to the Mediterranean sea close to Valencia in the south and close to Tortosa and the Ebro Delta in the east. The bulk of the Sistema Ibérico is located in the southern half of Aragon; the Prebaetic System rises south of the southernmost end of the Iberian System. The geology of the Iberian System is complex, it is composed of a haphazard and motley series of mountain ranges, massifs and depressions without a definite common petrologic composition and overall structure. Nummulite limestone and sandstone are common throughout the area; some of the parts of the system stand geologically isolated, interrupting the continuity of the whole, linked to the other parts through high plateaus of varying altitudes. Large zones of the mountainous Iberian System have undergone heavy depopulation since the early 20th century. There are many ghost towns and abandoned villages scattered across different parts of the Iberian System in Teruel Province.
A great number of surviving towns have only a residual population. In some cases many of the inhabitants are not natives anymore, but immigrants from Romania or the Maghreb working as contract laborers in agricultural activities; the exodus from the rural mountainous areas in Spain rose after General Franco's Plan de Estabilización in 1959. The population declined steeply as people emigrated towards the industrial areas of the large cities and the coastal towns where the tourism industry was growing. Other causes of high emigration have been the abandonment by the local youth of traditional agricultural practices that were the mainstay of the village economy, such as sheep and goat rearing, as well as the lifestyle changes that swept over rural Spain during the second half of the 20th century; the heavy depopulation has favored wildlife, so that one of the last colonies of griffon vultures in Europe is in the Iberian System. Wolves and eagles are relatively common in the lonely heights. Among the mammals, the Spanish ibex, roe deer, wild boar, European badgers, common genets, among others, have their habitat in many of these desolate mountain ranges.
The most common reptiles in the Iberian System are Lacerta lepida, Psammodromus algirus, Psammodromus hispanicus, Podarcis muralis and Podarcis hispanicus. Chalcides chalcides, Chalcides bedriagai and Anguis fragilis, are rarer; the snakes present in these mountains are Natrix maura, Natrix natrix, Malpolon monspessulanus, Elaphe scalaris, Coronella girondica, Coronella austriaca and Vipera latastei. Some amphibians are abundant in or near ponds and rivulets throughout the whole system, such as Rana perezi, Bufo bufo, Bufo calamita, Alytes obstetricans, Triturus marmoratus and Lissotriton helveticus, the latter at high altitude, whether in intermittent or permanent bodies of water. Hyla arborea and Salamandra salamandra are somewhat rarer, but still having a wide distribution in humid forested zones; the Iberian ribbed newt, however, is found in the mountainous areas. Aquatic invertebrates, including the Austropotamobius pallipes crayfish, certain fishes, such as Salaria fluviatilis and Cobitis paludica are common in the upper course of the Sistema Ibérico rivers.
Some mountain streams have been stocked with trout. Traditional cattle rearing activities so important in central Iberia, still survive on dry grasslands in certain villages around the system. There are a number of hunters visiting some of the ranges those that are closer to the urban areas and on weekends; some ranges have forested patches, consisting of Pinus pinaster, Pinus sylvestris and Pinus uncinata pines and Quercus rotundifolia, Quercus pyrenaica and Quercus faginea oaks Fagus sylvatica beeches and Betula pendula birches grow in some humid slopes, where Pteridium aquilinum, Polypodium vulgare ferns may be found. Other ranges are rocky and quite bare with heath, broom as well as thyme and Festuca and Nardus stricta grasslands. Thin forest or shrubland may include Juniperus communis, Juniperus thurifera, Cytisus purgans, Erinacea anthyllis and Calluna vulgaris shrub; the southern slopes are drier than the northern ones and may be subject to wildfires in periods of prolonged drought in the summer.
Bogs are not common in the Iberian Peninsula, but high altitu
La Jacetania is a comarca in northern Aragon, Spain. It is located in the northwestern corner of the Zaragoza provinces; the administrative capital is Jaca, with 13,374 inhabitants the largest town of the comarca. The area is famous for its ski resorts. Jacetania borders with Navarre in the west. Most of its territory is mountainous, with the ranges of the Pyrenees and Pre-Pyrenees covering most of its area; the name of the comarca originates in the ancient Iberian tribe of the Iacetani. This comarca was the birthplace of the historic County of Aragon; the traditional names of the towns, when different from the official name, are in brackets.
