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 caused by 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 the formation of mountain ranges, which are the form of 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.

Mountains are formed by the movement of the earth's crust.

The earth's crust is made up of six tectonic plates, which collide and squeeze each other in the process of constant motion, forming mountains. Mountains can be slowly eroded by rivers, climatic effects or glaciers. Some mountains form individual peaks, but most of them join together to form mountain ranges.

The highest mountain on Earth is Mount Everest in the Asian Himalayas, with an altitude of meters.

Mountains are formed by volcanism or continental drift (plate collisions), which cause geographical factors such as folding, faulting, uplifting, sedimentation, and erosion. For example, the Himalayas are plate extrusion movements caused by the collision of two continental plates, the Eurasian plate and the Indo-Australian plate. The Appalachian Mountains on the east coast of North America belong to the paleocontinental terrain and were formed by erosion.

Mountains and Humans. Mountains are less suitable for human habitation, so most humans prefer to live on flat ground (unless necessary), because the climate in the mountains is usually harsh, and the terrain is limited by the terrain and cannot develop into large cities, but the gently sloping mountains are still suitable for farming.

At high altitudes, there are fewer people living at higher altitudes due to a greater lack of oxygen and greater vulnerability to UV damage. In addition, 40 to 50 percent of people living at low altitudes who spend more than 3,500 meters above sea level for more than a few hours will develop mountain sickness (a disease in which the body develops due to low oxygen concentrations at high altitudes).

Mountains can be divided into tectonic mountains, erosion mountains, and accumulation mountains according to their genesis

1. Tectonic mountains are formed by tectonic movements in the earth's crust. Because of the movement of the earth's crust, the formation of folded mountains due to a large area of folds in the surface rock layer of the earth's orange fissure, or the formation of fault block mountains due to the rise of crustal faults are all tectonic mountains.

2. Erosion mountains are mountains that were originally plateaus or tectonic mountains, and were later eroded and divided by external forces such as flowing water and wind.

3. A mountain is a mountain formed by the accumulation of certain substances on the surface.

Tectonic mountain

Mountains formed by tectonic movements in the earth's crust are called tectonic mountains. Because of the movement of the earth's crust, the folded mountains are formed due to the folds of a large area of the surface rock layer, or the fault block mountains formed by the crustal faults are all tectonic mountains. For example, the Himalayas and Taihang Mountains in Asia and the Andes Mountains in South America are formed by the movement of crustal plates and the squeezing of silver.

Erosion of mountains

Originally a plateau or tectonic mountain, a mountain that was later eroded and divided by external forces such as flowing water and wind for a long time is called an erosion mountain. The water eroded the mountain into a hollow, and after the cavity collapsed, it was washed into a valley by the current, thus forming a series of mountains.

Stacked mountains

A mountain formed by the accumulation of certain substances on the surface of the earth is called a stacking mountain. The shape of the mountain is symmetrical and it generally stands in isolation above the low plains. Volcanoes, for example, are the most common accumulation mountains.

There are many reasons for the formation of mountains, some mountains are caused by volcanic eruptions, there are magma accumulation, and some mountains are due to the earth squeezing around, over time, some places are convex, others are concave, the convex places form mountains, and those concave places become basins.

Cosmic dust is a fine rock particle floating between the universes, and its size is about millimeters. But don't look down on the dust because of its small size, its microscopic components are composed of elements such as carbon, iron, oxygen, silicon and magnesium.

Mountains are usually created by plate collisions or volcanism.

The Honghao sedan mountain formed by the tectonic movement of the earth's crust is called a tectonic mountain, which was originally a plateau or a tectonic mountain, and was later formed by long-term erosion and division by external forces such as flowing water and wind, which is called an erosion mountain, and a mountain formed by the accumulation of certain substances on the surface is called a stacking mountain. There are four forms of plate drift, and the landform environment formed by different forms is different, and the landform that can form a mountain is called the convergence boundary, which is formed by the collision of two plates of similar density and thickness.

It is worth noting that plate movements only occur at the intersection of plates and plate socks, but in addition to the six major plates we are familiar with, there are also small plates in each large plate, such as the Amur plate.

World-famous mountain ranges

The Andes Mountains are on average 241 kilometers wide from east to west, with the widest being between Arica and San Tacloz at about 750 kilometers. The average elevation of the mountain range is 3,660 meters, with many peaks covered with snow all year round and more than 6,000 meters above sea level. At about 7,500 kilometers long, it is three times the length of the Himalayas and the longest mountain range on land, compared to the ocean floor and the longest mountain range on Earth.

The main mountain range in the eastern part of Australia in the Great Dividing Range, from the Cape York Peninsula in the north to Victoria in the south, is roughly parallel to the coastline, about 3,000 kilometers long and 200 to 300 kilometers wide, and the highest peak, Mount Kosciuszko, is the highest point in mainland Australia, with an altitude of 2,230 meters. The ridge is the watershed of the Indian and Pacific Ocean water systems, hence its name.
