Which is the highest mountain in the world? I believe many friends think of Mount Everest first.
Indeed, Mount Everest is the highest mountain in the world. To be exact, Mount Everest is the highest mountain in the world. The altitude of a mountain is calculated from the sea level. The altitude of Mount Everest is 8844.43 meters. This is the height of rock surface at the top of Mount Everest measured by our National Bureau of Surveying and mapping in 2005, which is the authoritative data. Mount Qomolangma is 233.43 meters higher than the second highest peak in the world. From the altitude, it is the highest peak in the world.
What you may not know is that the altitude of our country is calculated from the Yellow Sea near Qingdao. This is because the sea level is different in different parts of the earth. For example, in Central America, the sea level of the Pacific Ocean to the west of Panama is 20 cm higher than that of the Atlantic Ocean to the East. Therefore, our country adopts the Yellow Sea near Qingdao as the standard sea level when measuring the altitude.
The altitude of Mount Everest is 8844.43 meters. However, when we came to the Base Camp No. 2 at the foot of Mount Everest, we saw that Mount Everest was far less than 8800 meters. This is because the No. 2 base camp at the foot of Mount Everest has an altitude of more than 5200 meters. From here, the height of Mount Everest is only 3600 meters. The height of Mount Everest is called relative height. This is the part of Mt. Everest that really rises.
Due to the difference of sea level in different parts of the world, the height data of peaks in different parts of the world are also different. In recent years, some scientists have put forward another method to measure the height of mountain peaks, which is very interesting. This method no longer uses the sea level as the standard, but uses the earth's center as the starting point for measuring mountains.
The center of the earth is the most central point of the earth. Taking it as the starting point for measuring mountains is the same standard for mountains anywhere on the earth. If the earth's mountains are measured from the center of the earth, is Everest still the "highest" mountain in the world? The result is beyond our expectation. From the center of the earth, Mount Everest is no longer the highest peak on earth.
