How Mountains Are Formed Origin and characteristics of mountain ranges

The Earth's tectonic plates move, squeezing and uplifting, forming mountain folds.

Geologists believe that the main driving force for the formation of mountains is the horizontal extrusion of the earth's crust. One is the horizontal extrusion in the east-west direction due to the change in the speed of the earth's rotation;The other is the compression of the earth's crust towards the equator due to the different linear velocities of the earth's rotation at different latitudes. These two extrusions, combined with the distortion caused by uneven forces in the earth's crust, form mountains of various directions.

Generally speaking, the more solid and rigid parts of the earth's crust tend to break when the earth's crust moves, rising or falling relative to each other on both sides of the fracture, and sometimes protruding from the ground to become a high mountain.

Some of the weaker areas of the earth's crust tend to be more susceptible to the violent movement of the earth's crust and produce folds and uplifts, resulting in mountains such as many mountain ranges around the world.

After the earth's crust caused the unevenness of the ground, and then through the erosion of climate, flowing water and glaciers, it has the image of the mountains and mountains that it has today.

However, due to the crustal movement of the earth, some Cenozoic mountain ranges are still rising until now, such as the Himalayas in China.

The Earth's tall mountain ranges are folded mountains that are formed by the squeezing of continental margins or the collision of continental plates. The world's fault block mountains are less noticeable, they are caused by fault activity. Volcanoes can form in folded or faulted mountains.

1. When two continental plates collide with each other, the edge of the plate chain folds under the action of pressure, and the folded mountain range is formed.

2. The dome mountain range is formed due to the continuous erosion of the surrounding terrain by a large amount of lava pouring into the surface of the ground.

3. When cracks appear in the crust, the pressure from the ground forces some rock layers to rise and some rock layers to fall, and the rock layers are stacked on top of each other to form a fault-block mountain range.

4. Volcanic mountains are formed by magma erupting from the surface of the earth's crust.

5. The plateau mountain range is a flat land with a higher altitude than the shed, and the canyons in it are formed by erosion.

1. When two continental plates collide with each other, the edge of the plate produces folds under the action of pressure, and folded mountains are formed.

2. The dome mountain range is formed by the continuous erosion of the surrounding terrain by a large amount of lava underground rushing to the surface. Trillion noise.

3. When cracks appear in the crust, the pressure from the underground forces some rock layers to rise and some rock layers to fall, and the rock layers are stacked on top of each other to form a mountain range.

4. Volcanic mountains are formed by magma ejecting out of the surface of the earth's crust.

5. Plateau mountains are flat lands with high altitudes, and the canyons in them are formed by erosion.

Reason: Mountains are mainly formed by the action of internal forces. When the surface rock layer is subjected to forces from the earth's interior, a fold fault occurs, causing some places to bulge into mountains.

Mountains can be divided into the following four types according to the way they are formed.

The two plates of the folded mountain push against each other, and the earth's crust bends and deforms, forming mountains.

Volcanic mountain magma erupts from deep in the earth to form volcanoes, spewing lava, ash, and rock blocks to form tall volcanic cones.

Fault Mountains: The earth's tectonic plates collide with each other, causing faults or cracks in the earth's crust and huge rock blocks being squeezed up.

The magma beneath the crust of the crown mountain rises upward, causing the rocks on the earth's surface to bulge upwards to form the crown mountain.

A mountain range is a mountain body that extends in a certain direction and includes several mountains and valleys, which is called a mountain range because it resembles a vein. Mainly due to the action of internal forces in the movement of the earth's crust, there are obvious folds, which are different from mountains, while mountains are under the action of a certain force, and the fold phenomenon is not obvious.

There are four types of mountain ranges: folded mountains, broken block mountains, volcanic mountains, and crown mountains. Fold mountains are formed by the folds of the edge of the plate under the action of pressure when two continental plates collide with each other, such as the Himalayas and the Alps.

Most of the mountains on Earth are mainly caused by tectonic plate movements, extrusions, collisions, etc.

The role of volcanoes.

Summary. Hello Hello and happy to answer for you Major Mountains are the skeleton that makes up the terrain, also known as the skeleton of the landscape, and often become the boundaries of the terrain area. The direction in which the mountain range extends is called the strike.

China's mountain ranges are mostly northeast--- southwest and east-west. 1. There are three main columns and five mountains in the east-west direction: the northern column is the Tianshan Mountain and the Yin Mountain; The middle column is the Kunlun Mountains and the Qinling Mountains; The southern column is the South Ridge.

2. There are three main columns --- seven mountains in the northeast and southwest: the west column is the Daxing'an Mountains, Taihang Mountain, Wushan Mountain and Xuefeng Mountain; The middle column is Changbai Mountain and Wuyi Mountain; The eastern column is the Taiwan Mountains. 3. There are two main mountains in the northwest --- southeast:

Altai Mountains and Qilian Mountains. 4. There are two main mountain ranges running north-south: Helan Mountain and Hengduan Mountain.

5. Arc-shaped mountain system The Himalayas are a huge arc-shaped mountain range, which stretches on the southwest border of China and is connected with the Hengduan Mountains to form a huge arc-shaped mountain system. <>

Ok thanks.

What are the main topographical areas of our country?

The main topographic areas of China are mountains, plateaus and hills. China's mountainous erections, Gaoyin Shenyuan and hills account for about 67% of the land area, and basins and plains account for about 33% of the land area. The mountain ranges are mostly east-west and northeast-southwest, mainly including Afeng'er Mountain, Tianshan, Kunlun Mountain, Karakoram Mountain, Himalayas, Yinshan Mountain, Qinling Mountains, Nanling Mountains, Daxing'an Mountains, Changbai Mountains, Taihang Mountains, Wuyi Mountains, Taiwan Mountains, Wushan Mountains and Hengduan Mountains.
