Mount Everest is still growing

The formation and constant growth of Mount Everest are related to the mutual movement of the earth's plates.

​​About 250 million years ago, Africa, India, South America and Australia were not separated. They were on the same continent, called Pangia. In the next few million years, this huge continent shattered and very slowly formed the same continent as today.

​​About 70 million years ago, the Indo-Australian plate began to move on the surface of the earth. It moved very fast, drifting 15 centimeters north every year. The power of

​​to promote plate movement comes from internal heat in the depths of the earth, which can escape effectively only through convection.

​​The Indian plate collided with the Eurasian plate around 55 million years ago. There used to be an ocean called Tethys between them. Due to the rapid movement of the Indian plate, by 25 million years ago, it almost completely closed the middle ocean and squeezed the sediments on the ocean floor.

​​Because the sediments are very light, they did not sink with the plates, but crumpled into mountains- Himalayas mountains.


​​Everest is the highest mountain in the world, but most of the rocks on its ground are limestone, and these rocks are formed on the sea floor. Today, people can still find fossils of ancient animals on the seabed in the Himalayan sedimentary rocks and volcanoes on their edges.

  • The reason why Mount Everest is so long

The world's highest peak, Mount Everest, was formed under the combined action of the natural forces such as mainland shuffling and orogenic mechanics.

​​Until today, the Indian plate and the Asian plate are still squeezing each other at a speed of 5.08 cm every year, which makes the entire Himalayas still rising, and Mount Everest also increases by about 1.27 cm every year.


​​Everest is the highest mountain in the world, so it attracts mountaineers from all over the world who want to climb the challenge.

How dangerous is it?

The first summit of Mount Everest was in 1953. Because of the unpredictable weather and bad weather, by 1987, only about 200 people reached the summit.

​​Since 1990, climbing Everest has gradually formed a commercial operation. As of 2018, the Himalaya database reported that has known that 295 people died while climbing Mount Everest , and 5,294 people have successfully climbed 9159 times. The death rate of

​​climbing Mount Everest is about 1.2%, and means that one out of every 100 climbers will die on the way .

​​According to a climber who has climbed Mount Everest nine times, she saw 7 bodies in the last part of the climb in 2018. One of the corpses is very frightening. "He seems to be alive because the wind moved his hair." Upon closer inspection, she found that his face was frozen and disfigured.

The climber "green boots" who died in the northeast ridge of Mount Everest in 1996.

​​Even though Mount Everest is dangerous, it still attracts people from all over the world to challenge. It is almost overcrowded now, and there are more and more people every year, causing serious traffic jams during the climbing season.

"It's like queuing in a busy weekend in a ski resort." Nepalese climbers posted this photo of the crowd trying to reach the top of the mountain on social networking sites. It spread quickly and citedI posted a discussion among netizens about the problem of overcrowding in the mountains. What does

look like?

The top of Mount Everest is a small snow dome, about the size of a dining table, where six or seven climbers can stand here to enjoy the scenery.

​​However, in the busiest days of Mount Everest, climbers must take turns to stand here to truly stand on top of the world, and they can only stay there for 20 minutes at most.


Summary

In order to reduce the damage to the environment of Mount Everest, my country has greatly reduced the issuance of climbing permits, but on the other side of the mountain, Nepal, climbing Mount Everest has become a big deal. According to the local Ministry of Tourism, they collected a license fee of US$5.2 million in 2018.

​​However, what is worrying is that the local guide service is not professional. Of the 21 climbers who died on the 8,000-meter peak in 2019, 15 were clients of an expedition organized by Nepal.

​​In short, there are still many places worthy of our investigation and research on Mount Everest. I hope that it will not only become a place for wealthy people to show off their online celebrities.
