The height of Mount Everest often changes. What is the reason for the height change? The highest mountains (such as Himalayas or Andes Dance) are all folded mountains, which are formed by the collision of inland edges and along the boundary of the fusion plate. The height of mountains is mainly determined by the construction process inside the earth or the erosion process that shapes the earth's surface, which has always been a difficult problem in earth science demonstration. A new study by Amin Dielforder, a German geographical research center, shows that the erosion of rivers and glaciers has no significant effect on the height of mountains. Researchers have solved the long-standing debate by analyzing the strength and calculation of various plate boundaries on one side of the plate boundary.

By calculating the forces on the boundaries of different plates on the earth, the researchers came to this surprising result, and the data they used provided information on the boundary strength of this plate. The researchers collected global data of mountain ranges with different heights (Himalayas, Andes, Sumatra and Japan) and calculated the obtained data to calculate the force generated by the ridge of each mountain range. In this way, they found that in the active mountains, the height and height of the dynamic and fan-shaped boundary mountains are balanced.

Although mountain areas have been studied in different climatic zones, the erosion change rate is large, but this force exists in all mountain areas. The results show that mountains can react in the process of surface and grow under rapid erosion, thus maintaining the balance of power and the height of mountains. This new discovery provides more opportunities for long-term development and the growth of mountains. Judging from the rock structure of Mount Everest, it is mainly composed of three parts: the northern layer, the adhesive tape layer and the beads. So, when did the height of Mount Everest change? How long has this change gone through? In short, geologists say that the historical height of Mount Qomolangma Maka has exceeded 65,438+02,000 meters. Of course, this figure is not obtained by patting the head, but by analyzing and calculating the rocks that have happened.

Geologists have observed the north, and found that this area has experienced great rock deformation reaction, and the rocks in these areas have reached about 150% stretching, which should have happened 1300 years ago. At the same time, the deformed rocks found on Mount Everest directly confirm that the geographical location of Mount Everest is actually located in the fault zone of Himalayan hills.
