What is the highest mountain in the world? Which country does it belong to and where is it?

Mount Everest is the main peak of the Himalayas, located at 86.9 degrees east longitude and 27.9 degrees north latitude. Located in the eastern section of the China-Nepal border, the northern slope is in Dingri County, Tibet, China, and the southern slope is in the Kingdom of Nepal. "Everest" means "the third goddess" in Tibetan. As early as 172 1 year, the Imperial Panorama compiled by the Qing government in China accurately marked the geographical location of Mount Everest, and named it "Mount Everest Alin" according to Tibetan (Alin is Manchu, meaning "peak"). 177 1 year, the map of Gan Long Neifu replaced "Qomolangma" with "Qomolangma", which has been used ever since.

Mount Everest has four peaks over 8000 meters and 38 peaks over 7000 meters, so it is also called the roof of the world. There are many large modern glaciers at the foot of Mount Everest, and glacier landforms such as knife ridges, tinder and ice buckets are widely distributed.

Of course, the first peak in the world is also the place that the world mountaineering attracts attention and yearns for. However, the terrain of Mount Everest is extremely steep and the environment is extremely complicated. Snow line height: 5800 ~ 6200m on the north slope and 5500 ~ 6 100m on the south slope. There are three steep walls (north wall, east wall and southwest wall) between the northeast ridge, southeast ridge and west ridge, and 548 continental glaciers are distributed between these ridges and west ridge, with a total area of 1457.07 square kilometers. The climate of Mount Everest is complex and changeable, even in a day, it is often unpredictable. Generally speaking, the rainy season is from the beginning of June to the middle of September every year, and the strong southeast monsoon leads to frequent rainstorms, misty clouds and unpredictable ice and snow. 1/kloc-0 from mid-October to mid-February of the following year, controlled by a strong northwest cold current, the temperature can reach -60℃, the average temperature is between -40℃ and -50℃, and the maximum wind speed can reach 90 meters per second. Only two periods in a year are the best seasons for mountain climbing. One is from the beginning of March to the end of May and the other is from the beginning of September to the end of 10. However, considering various uncertainties, the actual good weather always adds up to only 20 days. During these two periods, the wind speed was low and there was little rain and snow above 8000 meters above sea level.

Seen from China, Mount Qomolangma is steep and steep. The top of Mount Qomolangma is covered with ice and snow all year round, showing a shocking pyramid shape. But the scenery in Nepal is very broken, so it's a pity that I didn't see Mount Everest when I went to Tibet.

There are 15 alpine glaciers with an area exceeding 10 square kilometers on Mount Everest. The largest flannel glacier is 26 kilometers long, with an average thickness of 120 meters, and the thickest part is over 300 meters. These glaciers are of various types, and their upper limit is generally 7260 meters. The replenishment of glaciers is mainly formed by the snow metamorphism in the two major precipitation zones of the Indian Ocean monsoon belt. One of the largest and most famous is the complex valley glacier-Rongbu Glacier. The average width of flannel glacier ice tongue is14km, with an area of 86.89 km2.

There are all kinds of magnificent and rare ice towers, ice floss, ice bridges and ice towers on the glacier. There are ice cliffs as high as tens of meters, light and dark ice cracks with traps step by step, and dangerous ice collapse areas.
