Where are the mountains of Cordillera? Cordillera Mountains: Description

Cordillera – the mountains, a huge system which occupies the western outskirts of the continent of North America. They stretch for about 7 thousand. Km. Cordillera – the mountains, a great variety of natural conditions. A number of features are characterized and it defines their uniqueness among other mountain systems of the planet.

Overview of Cordillera
Where are the mountains of Cordillera? Mostly they learned in submerydyonalnom direction. Within five orotektonycheskyh zones of different ages formed these mountains. Cordillera are composed of a significant share of the Highlands (25-3 thousand. Meters or more above sea level). They have active volcanism and high seismicity. The great length of the mountains from north to south has led to the presence here of many spectra of altitudinal zonation. Cordillera – the mountains, formed at the junction between the lithosphere plates. The boundary between them almost coincides with the line of the coast.

The composition of the Cordilleras
The third part of the entire continent occupies a mountain fold-hlybovaya system. It has a width of 800-1600 km. The structure consists of mountain plateau mizhhirnyh troughs, ridges and volcanic plateaus and mountains. Young deformation, volcanic, denudation experienced Cordillera, which determined their present form and zamaskyrovalo many geological structures that appeared earlier. A heterogeneous mountain system in both cross and longitudinal direction.

Asymmetric structure surface of the continent, where the Cordillera mountains. They occupy the western part, on the east – low mountains and vast plains. The western part is located at an altitude of 1700 meters, and east – 200-300 m. 720 meters is the average height of the continent.

Cordillera – the mountains which are composed of a series of mountain curves, which are extracted mainly in the direction from northwest to southeast. On p. McKenzie, Mts. Brooks, Rocky Mountains is the eastern arc. Intermittent are formed from the inner plateau and plateau located west of these ranges. 1-2 thousand. Meters of their height. Cordillera – the mountains include the following highlands and plateaus, highlands Yukon and Columbia Plateau Plateau of British Columbia, the Great Basin, Colorado Plateau, a volcanic plateau and plateau Mexican highlands (inner part). Most of them are alternating hollows, ridges and flat table surface.
The highest mountain
Where are the mountains of Cordillera? Cordillera Mountains: Description
Cordillera of the western part of the system marked the highest ridges. This Aleutskyy Range, Ridge, Aleutian Islands, Alaska Range. The latter reaches a height of 6193 meters. It McKinley represented in the photo above the highest mountain. Cordillera – a system that includes the western part and the Cascade Mountains, Coast Mountains of Canada, Western Sierra Madre and the Sierra Nevada and Transverse Volcanic Sierra of the located here Pico de Orizaba (5,700 meters), etc.
To the west of their reduced height. Cordillera – the mountains, which smoothly pass in the flat part of the continent. Her take on the event or the Bay (California, Puget Sound, Cook) or plain (California valley, valley. Uyllamett). This coast continent formed ridges St. Elias, Chuhachskym, Kenayskym, island ridge of Canada and the Coast ranges USA. Chains Cordillera south of Mexican Plateau bifurcate. East rejected one of them, forming islands of the West Indies and underwater mountain ranges, then goes into the Venezuelan Andes. The second half extends through the Panama and Teuantepekskyy isthmuses to the Colombian Andes.

Why is the diversity of mountain terrain?
It is associated with various areas under the land and the history of their development. Not immediately formed in its present form the mainland. Cordillera Mountains in the current form emerged through various processes occurring at different times in the continent.

For Lavrentyyskoy high, said the oldest geological structures in the landscape is characterized surface alignment, the formation of which began in the early Paleozoic. Upland modern wavy surface resistance caused different species to denudation and uneven tectonic movement. Lowering the central part of the covering caused Quaternary glaciation, because of which formed the modern Hudson Bay basin. In addition, under his influence the accumulation of water-ice and moraine deposits that formed the type of terrain (moraine-hilly).
Large and central plains are the type of reservoir. Under the influence of denudation processes in different places, depending on the characteristics of occurrence of different rocks formed kuэstovye ridge (Great Lakes), stepped plateau (the Great Plains), middle and lowland erosion (Ouachita Mountains, Ozark).
It is the most difficult terrain and Cordillera. Band compression crust is crossed by numerous faults, starting from the ocean floor and end on land. Not yet completed horoobrazovatelnyy process. These are volcanic eruptions (eg, Popocatepetl and Orizaba) and earthquakes that occur here occasionally.

Minerals
Where are the mountains of Cordillera? Cordillera Mountains: Description
As you know, many different minerals can be found wherever there are mountains. Cordillera – is no exception. This vast reserves of ferrous and nonferrous metals. With non-metallic can identify oil which is in mizhhirnyh troughs. Brown coal reserves are in the region of the Rocky Mountains (their internal basins).
Climate
Characteristic climate continue description of the mountains. Cordillera are on the way oceanic air masses. Because of this, in the east dramatically weakens the influence of the ocean. This climatic feature Cordillera displayed on soil and vegetation, the development of modern glaciation, altitudinal zonation. Elongation north-south mountain ranges causes temperature differences in summer and winter. In winter it is between -24 ° C (near Alaska) to +24 ° C (Mexico, south of the country). In summer the temperature ranges from +4 to +20 ° C.
rainfall
In the north-west falls most rainfall. The fact that this part of the Cordillera is located towards the western winds blowing from the Pacific Ocean. Precipitation here – about 3000 mm. The least is moist tropical latitudes, as the oceanic air masses were not achieved. Low rainfall also explains how cold that runs along the coast. The interior Cordillera highlands also not very moist. Mountains located within the temperate, subarctic, tropical and subtropical climate zones.
The rivers and lakes of the Cordillera
Where are the mountains of Cordillera? Cordillera Mountains: Description
A significant part of the western rivers of the continent it originated in the Cordilleras. Mainly their food is snow and ice, the summer flood accounts. These mountain rivers, steep. The largest of them – the Colorado and Columbia. Or Glacial lakes are of volcanic origin Cordillera. On internal plateaus are shallow saline water bodies. It remains existed here long ago, during the humid climate, large lakes.
plantage

Very diverse flora of the Cordillera. Coniferous forests with a unique view are up to 40 ° C. w. For species composition they are very rich. Spruce, Chamaecyparis, fir, cedar (red cedar) are typical representatives. Pitch pine trees reaching 80 meters. Between them virtually no woody undergrowth. However, various shrubs grow here in abundance. Much ground cover of moss and ferns. In coniferous forests by driving south begin to come across the sugar pine, white fir, yellow pine. Sequoia evergreen appears further south. As increasing dryness, south of 42 ° C. w., bushes changing forests. They juniper, heather, and their height is usually not more than two meters. You can sometimes find different types of evergreen oak. Moisture climate in the interior of the Cordillera decreases. They are characterized by dry forests and areas solyankovyh and wormwood deserts. Prepared rain covered slopes to an altitude of 1200 m evergreen forests.
Animals that live in the mountains of the Cordillera
Where are the mountains of Cordillera? Cordillera Mountains: Description
Where are the Cordillera mountains, you can find grizzly brown bear – a major predator of the continent of North America. Bear baribal has long black fur, resides in the southwest of the system. It destroys the cattle and spoil the crops. There are many lynxes, foxes, wolves. In the southern mountains often are arthropods, lizards, snakes. In addition, there lives otrutozub – the only legless venomous lizard. Large animals in places where people live or destroyed or extremely rare. Bison and pronghorn (antelope rare) saved only thanks to the current national programs in North America. Only in reserves can be seen today rich fauna.
