Belonging to the Cordillera is the mountain range that the Cordillera is made up of

1. The Cordillera is the longest folded mountain system in the world. It runs through the western part of the American continent. It stretches for about 15,000 kilometers from Alaska in the north to Tierra del Fuego in the south.

2. The geomorphological structure of the Cordillera mountain system is self-contained, it is composed of a series of longitudinal mountain ranges, intermountain plateaus, basins and valleys, but its northern and southern sections are slightly different

The northern section (North America) can be roughly divided into three vertical belts: eastern, central and western.

a The Rocky Mountains are the main part to the east, with Mount Brooks to the north and Sierra Madre Oriental to the south on the eastern side of the Mexican Plateau.

b The central part is an intermountain plateau basin. From north to south there are the Yukon Plateau, the British Columbia Plateau, the Columbia Plateau, the Great Basin, the Colorado Plateau, and the Mexican Plateau.

c The western part is mountainous on the edge of the Pacific Ocean. It consists of mountains on the east and west sides and a depression valley in the middle. The eastern mountains are Alaska Mountain, Canadian Coast Range, Cascade Mountain, Sierra Nevada and Sierra Madre West from north to south, generally 2000 3000 meters high, of which Mount McKinley in the Alaska Range is 6193 meters high, which is the highest peak in North America.

The mountains on the west side are bordered by the Aleutian Mountains, Chugachi Mountains, and Ereas Mountains from north to south, the Alexander Islands and Vancouver Island, which are island mountains to the south, and the U.S. Coast Mountains and the California Peninsula to the south.

The southern section (South America) is dominated by the Andes Mountains, with coastal mountains to the west and the front Cordillera Mountains to the east.

Rocky Mountains and Andean Mountains.

The Cordillera mountain system consists of the Rocky Mountains in western North America and the Andes Mountains in western South America. The Cordillera Mountains are the longest folded mountain system in the world, running through the western part of the American continent. The structure is complex, composed of a series of fold faults, and the earth's crustal activity continues to this day.

Cordillera:

The Cordillera belongs to the Mesozoic fold belt. Its structure is complex, consisting of a series of folds and faults. Mainly formed in the second half of the Mesozoic and the Tertiary Period, the fold fault structure is complex, the crustal activity is still continuing, and it is an important part of the Pacific Rim volcanic belt.

Mountains generally run north-south or northwest-southeast. It consists of a series of parallel mountain ranges, intermountain plateaus, and basins. The North American Cordillera is wide and low at an altitude of about 800 1600 km wide and 1500 4000 m above sea level.

The topographic structure consists of two mountain belts in the east and west and a wide intermountain plateau basin. From Mexico to the south, the mountain system narrows and divides into two branches: one extends south through the Isthmus of Central America into the South American continent, and is mostly volcanic, rugged mountainous terrain.

1. The Cordillera mountain system in North America is dominated by the Rocky Mountains, with Mount Brooks to the north and Sierra Madre East on the east side of the Mexican plateau to the south. The Rocky Mountains stretch 5,000 kilometers from north to south, generally 2,000 meters high, and the southern peak can reach more than 4,000 meters.

2. The Rocky Mountains, also translated as the Rocky Mountains, are the backbone of the American Cordillera Mountains in North America, composed of many small mountain ranges, known as those of North America"Spine"The main mountain range, which stretches from British Columbia, Canada to New Mexico in the southwestern United States, stretches for more than 4,800 kilometers from north to south, and is vast and lacks vegetation.

The Cordillera mountain system is made up of the Rocky Mountains of North America and the Andes Mountains of Latin America.

The Cordillera is the longest mountain system in the world, located on the American continent and consisting of the Rocky Mountains and the Andes.

The Cordillera is the longest folded mountain system in the world. It runs through the western part of the American continent. It stretches for about 15,000 kilometers from Alaska in the north to Tierra del Fuego in the south.

It belongs to the Mesozoic fold belt. The structure is complex, composed of a series of fold faults, and the earth's crustal activity continues to this day. Mountains generally run north-south or northwest-southeast.

It consists of a series of parallel mountain ranges, intermountain plateaus, and basins. The rise of tall mountain systems and their barrier role have had a great impact on the climate of the South American continent, the distribution of hydrological networks, the regional differentiation of geographical environment, the cultural landscape and the layout of communication routes. There are copper, lead, zinc, tin, gold, silver, petroleum, coal, sulfur, saltpeter and other mineral resources.

The Cordillera mountain system consists of the Rocky Mountains of North America and the Andes Mountains of South America, with the Andes being the longest mountain range in the world.

The Cordillera Mountains run through the north and south of the American continent and the west. From Alaska in the north to Tierra del Fuego in the south, it stretches for about 10,000 kilometers and belongs to the Mesozoic fold belt. The structure is complex and consists of a series of folded faults.

It was mainly formed in the second half of the Mesozoic and the Tertiary Period, with complex fold fault structure, crustal activity continuing, and many volcanoes, which is an important part of the Pacific Rim Volcanic Belt. Mountains generally run north-south or northwest-southeast. It consists of a series of parallel mountain ranges, intermountain plateaus, and basins.

The Cordillera Mountains in North America are wide and low at altitudes, about 800 1600 km above sea level, with an altitude of 1500 3000 m above sea level.

Formation and evolution

The genesis of the Cordillera is mainly the result of the interaction between the oceanic and continental plates. This activity is closely linked to the opening of the Atlantic Ocean and the separation of the southern Gondwana continent, especially from Africa. The Cordillera was mainly formed during the Mesozoic-Cenozoic.

In the first half of the Mesozoic, the Cordillera trough was in the subsidence and accumulation stage, and at the end of the Jurassic, there were several orogenies at the trough, accompanied by extensive magmatic intrusions. At the end of the Cretaceous period, the Laramie movement set off a large-scale orogeny, which affected from Alaska in the north to the Greater and Lesser Antilles in the south, and caused a strong orogenic movement in the Andean trough in South America, creating the fold structure of the entire Andes.

At this point, the area of the American continent expanded westward by a big step. This movement continued into the Tertiary period. After the Cenozoic, the Cordillera entered a period of predominantly erosion, resulting in a large number of continental sediments in the intermontane basins, piedmont depressions and lowlands, and a huge upward movement in the Pliocene, which continued until the Quaternary and beyond, which caused the Cordillera to re-uplift, fold, fracture and be accompanied by magmatic intrusion, lava eruptions and volcanic activity.

As a result of this movement, the Cordillera not only has the characteristics of a young modern tectonic landform, but also connects North and South America through the Isthmus of Central America and makes it the longest mountain in the world. The early Quaternary period had a certain influence on the Cordillera mountain system, and the northern section (North America) was earlier than the southern section (South America), and the glacier coverage was larger than that of the southern section.

The British Columbia Highlands is the glacial center of the northern part of the Cordillera, and the southern part is dominated by alpine glaciers. Intense glacial erosion has reshaped the face of the Cordillera.
