How many mountain systems are there on the earth and where are the three major mountain systems of t

Two mountain systems. The Cordillera Mountains in North and South America, and the Alps-Himalayas in Eurasia.

It is an exaggeration to say that China's large and small mountain systems alone include the Hengduan Mountains, the Wuyi Mountains, the Himalayas, the Gangdis-Nianqing Tanggula Mountains, the Karakoram Mountains, the Tanggula Mountains, and so on.

There are two famous mountain systems in the world:One is the Alpine Himalayas, which traverse the southern part of the Eurasian continent.

System. The second is the Cordillera Mountains that run from north to south on the east coast of the Pacific Ocean, which refers to the western part of the Americas.

Brief introduction. As the height of the mountains increases, the climate changes and the natural scene changes, which is the vertical natural zone unique to the alpine region. Due to the particularly high mountain, the vertical natural zone of Hima Bab Raya Mountain is very obvious.

For example, below 2000 meters, it is warm and humid, lush, and belongs to the evergreen broad-leaved forest belt.

At 3000 meters, hardy conifers increase and gradually become coniferous belts.

At 4000 meters, due to the lack of heat, it is difficult for trees to grow, and shrubs replace forests and become shrub belts; The higher reaches become alpine meadows.

lichens and other natural belts; Above 5,000 meters is the snow belt, which does not melt all year round.

Answer. The two most famous mountain systems in the world are the Alpine-Himalayan mountain system that runs through the southern part of Eurasia and the Cordillera mountain system that runs through the western part of North and South America

So the answer is: Alps-Himalayas; Cordillera

Analyse. The high mountain ranges on the land are mainly distributed in the two major zones of staring or chaos One is the Pacific coastal mountain range, such as the Cordillera mountain system that runs from north to south on the east coast of the Pacific Ocean from north to south and the western part of North America, which is mainly composed of the Rocky Mountains of North America and the Andes Mountains of South America The second is the mountain range belt that runs through the southern part of the Eurasian continent and the northwest of Africa, which generally extends in an east-west direction, mainly including the Himalayas, the Alps and the Atlas Mountains

All the mountain ranges formed on the Himalayan fold belt are collectively known as the Himalayan mountain system. The mountains formed on the Tianshan and Yinshan tectonic belts are called the Tianshan Mountains and the Yinshan Mountains respectively, and the mountains formed on the Kunlun and Qinling tectonic belts are called the Kunlun Mountains and the Qinling Mountains respectively.

A mountain system refers to a complex of several adjacent mountain ranges belonging to the same system that are closely related in morphology, genesis and structure and developed within the scope of a huge tectonic unit or a large tectonic system.

A complex of enormous mountain ranges that are connected and extended in a certain direction.

It is mostly distributed in tectonic belts, volcanoes, and ** belts, such as the longitudinal mountain system of the Pacific Rim in the Asia-Pacific region, and the transverse mountain system across Asia, Europe, and Africa. They are all controlled by the Earth's internal stress field and are the product of tectonic action.

The mountain range, which is a combination of mountains and valleys in between, stretches over a long stretch of the mountain. The direction in which a mountain range extends is called the direction of a mountain range. The course of the mountain range depends on the direction of action of the stresses that cause tectonic deformation. The larger mountain ranges for tens of kilometers, if not thousands.

For example, the Andes Mountains are 9,000 kilometers long, making them the longest mountain range in the world. Mountains are the backbone of the terrain, affecting the flow of rivers and even the differences in climate. Most of the huge mountain ranges on the surface are located in the folded belts formed by recent orogeny.

Such as the Pacific Rim and along the Mediterranean Belt.

The largest mountain system in the world is the Cordillera Mountains, which run through North and South America. The Cordillera mountain system includes the Rocky Mountains, the Coast Mountains, the Andes Mountains and other mountain ranges, and the Cordillera mountain system is composed of a number of parallel mountain ranges that run through the western part of North and South America, with an average altitude of more than 1000m.

The above content refers to the encyclopedia mountain system.

Alpine-Himalayan belt and Pacific mountain belt.

The Alpine-Himalayan belt is a huge east-west mountain system that spans south-central Eurasia and northern Africa, including the Alps in Europe, the Atlas Mountains in North Africa, and the Hindu Kush, Karakoram and Himalayas in Asia. This mountain range connects eastward through the Indochina Peninsula and Indonesia to the Sunda Islands and the Pacific Rim Mountain Belt.

The Pacific Rim Mountain Belt is mainly a huge mountain system with a north-south trend, including the Cordillera-Andes Mountains in the Americas, the Alaska Mountains, the Pacific Rim Mountains in Asia and Australia, and the island arc mountains such as Japan and the Philippines.

The Cordillera mountain system, which runs through the western part of the American continent, is the longest mountain system in the world. This mountain system stretches from Alaska in the United States in the north to Tierra del Fuego in Argentina along the western border of the North American and South American continents, with a length of 15,000 kilometers from north to south. This mountain system consists of the Coast Mountains, Rocky Mountains, Sierra Nevada, Sierra Madre, and the Andes Mountains of South America.

Between the mountains there are countless intermountain plateaus, intermountain basins, valleys, etc.

The mountain systems in North America are generally 1,500 to 3,000 meters above sea level, with the highest peak McKinley reaching 6,193 meters; Most of the mountain systems in South America are above 3,000 meters above sea level, among which Mount Aconcagua is 6,964 meters above sea level, which is the highest peak in South and North America.

The Cordillera Mountains were formed relatively late and were formed by the collision, extrusion and uplift of the American continental plate and the Pacific plate. It is one of the youngest mountain systems in the world, and volcanoes are active and frequent to this day.

The two most famous mountain systems in the world are:

The Alps-Himalayan mountain system that traverses the southern part of the Eurasian continent.

The Cordillera Mountains that run through North and South America.

There are two famous mountain systems in the world:The first is the Alps that traverse the southern part of the Eurasian continent.

Himalayas; Which before.

The second is the Cordillera mountain system on the east coast of the Pacific Ocean that runs from north to south in the western part of the Americas, consisting of the Rocky Mountains and the Andean Liquid Slow Vein.

Himalayas:The Tibetan word for the Himalayas means "home of snow". It is located on the Tibetan Plateau.

On the southern edge of the summit is the highest mountain range in the world. It is the natural boundary mountain of the East Asian continent and the South Asian subcontinent, as well as China, India and Nepal.

Bhutan, Pakistan and other countries are natural national borders.

From Kashmir in the west.

The Nanga Parbat Peak (8,125 meters above sea level) and the Nanga Bhava Peak (7,782 meters above sea level) at the great bend of the Brahmaputra River in the east, with a total length of 2,450 kilometers and a width of 200,350 kilometers.

There are two famous mountain systems in the world:

The first is to judge the Alpine-Himalayan system that crosses the source of the southern Eurasian continent;

The second is the Cordillera mountain system that runs from north to south on the east coast of the Pacific Ocean and runs through the western part of the Americas, consisting of the Rocky Mountains and the Andes.

The longest mountain system is the Cordillera mountain system. The Cordillera mountain system runs through North and South America.

The western part of the continent, located in North America called the Rocky Mountains, is located in South America.

The part is called the Andes. The entire mountain system stretches from Alaska in the north.

To the south of Tierra del Fuego, it stretches for about 10,000 kilometers and generally runs north-south, consisting of a series of parallel mountain ranges, intermountain plateaus and basins.

The Cordillera mountain system is an annual folded mountain system, and the tectonic activity has been very strong since the Cenozoic, and it has become an important part of the Pacific Rim volcanic belt, and volcanoes are very frequent. At the same time, as the geological forces continue, its height is still rising, which brings obvious vertical differentiation to the area.

The existence of the Cordillera mountain system has had a great impact on the climate of North and South America. The tall Cordillera mountain system is a natural barrier to water vapor in the Pacific Ocean, with precipitation of about 500 mm on the Pacific coast and a rainy zone north of 40°N, with a maximum of more than 2,000 mm.

However, after entering the intermountain plateau and basin area, due to the leeward position and the closed terrain, the annual precipitation is less than 500 mm, and the large basin and the Colorado Plateau are even less than 50 mm, indicating that it is decreasing from west to east. Book stuffiness.

Cordillera Mountains.

The longest mountain system in the world is the Cordillera mountain system. It runs through the western part of the American continent, borders the Taiqi Imperial Ocean in the west, connects the Central Plains of America in the east, starts from Alaska in the north, reaches Tierra del Fuego in the south, stretches for more than 15,000 kilometers, and is the longest mountain system in the world: the Cordillera mountain system is wide in the north and narrow in the south, and its northern section is dominated by the Rocky Mountains, with an altitude of about 2000-3000 meters, and the southern section is dominated by the Andes Mountains, with an average sea dust of 3000 meters.

There are two famous mountain systems in the world:

The first is the Mediterranean-Himalayan mountain system that traverses the southern part of the Eurasian continent and northwest Africa, consisting of the Himalayas and the Alps;

The second is the Cordillera mountain system on the east coast of the Pacific Ocean that runs from north to south across the North American continent and the western part of the South American continent, consisting of the Rocky Mountains and the Andes Mountains.

Introduction]: The Himalayas, also known as Mount Everest or Mount Everest, are the tallest and most majestic mountain systems in the world. It stands on the southern edge of the Tibetan Plateau, between China and India, Bhutan, Nepal and Sikkim.

From the Pamir in the west to the big bend of the Brahmaputra River in the east, it is more than 2,500 kilometers long. The average altitude is more than 6,000 meters, which is unmatched by any mountain system in the world. It has 14 peaks above 8,000 meters and more than 40 peaks above 7,000 meters.

Among them, Mount Everest, located on the border between China and Nepal, is the highest peak in the world.

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 extremely complex, composed of a series of fold faults, and the earth's crustal activity continues to this day. The mountain range is generally north-south or west-closed, north-southeast.

It consists of a series of parallel mountain ranges, intermountain plateaus, and basins. The rise of this tall mountain system and its barrier role have had a great impact on the climate of the South American continent, the distribution of hydrological networks, the geographical environment and regional differentiation, the cultural landscape and the layout of transportation routes. There are copper, lead, zinc, tin, gold, silver, petroleum, coal, sulfur, saltpeter and other mineral resources, which can be called "mineral treasure house".
