When we talk about the highest peak on Earth, it's easy to think of Mount Everest . It's a place that serves not only as a reference point for the highest point on Earth, but also as a meeting place and adventure destination for climbers and nature lovers alike. The entire mountain range where Everest is located is known as the Himalayas . It has different names depending on the region. For the Nepalese, it's called Sagarmāthā, the Chinese know it as Zhūmùlǎngmǎ Fēng, and the Tibetans call it Chomolungma.
In this article we will tell you all about the characteristics of Mount Everest , its origin and importance.
Key features
Although figures are given, there is some confusion regarding the actual height of this peak. What is certain and known for sure is that it is the highest point on our planet. However, it is not the largest or tallest mountain of all, since we can consider seamounts based on their altitude. For example, Mauna Kea is a volcanic mountain that measures over 10000 meters high from its base and is located on the ocean floor.
As we mentioned before, Mount Everest is part of the Himalayan mountain range and is located in Southeast Asia, between the Indian subcontinent and the rest of Asia. It reaches an altitude of 8.850 meters above sea level and covers an area of approximately 594,400 square kilometers. Some people liken this mountain range to a pyramid with three faces. The air at the highest points of this range is oxygen-depleted because it lies at the edge of the troposphere. Furthermore, it presents a significant challenge for all climbers, as the area is frequently battered by strong winds and freezing temperatures.
The summit is nothing more than a rocky peak surrounded by very hard snow that was surrounded by another layer of snow that can be reduced or increased over the years. It all depends on the temperatures and the glacial cycle. If the rate of snow accumulation is greater than that of abrasion, the glacier will continue to grow. We know that in the month of September the peak is somewhat higher than during the month of May. This corresponds to what we have mentioned about the glacial cycle.
Everest weather
The temperature is also not constant. It tends to vary with the seasons. At the beginning of the year, temperatures can reach -36 degrees Celsius, while in summer they reach -19 degrees Celsius.
During the monsoon season, which runs from June to September, intense storms occur with winds of up to 285 km/h . It's also worth noting that at these altitudes, atmospheric pressure is 30% lower than at sea level. This is one of the atmospheric variables that affects all climbers as they approach the summit.
A few meters below this summit lies the area known as the "death zone." This name is due to the lack of oxygen and extremely low temperatures found there that have caused several mountaineer deaths.
If we analyze the tropospheric profile at higher altitudes, we see that the temperature decreases as we gain altitude. The same occurs with atmospheric pressure. Thus, when we reach the highest layers of the Himalayas, we experience very low temperatures and very low pressures. These environmental conditions cause the snow and ice cover to increase. On the other hand, as we descend, both the temperature and pressure increase, and the amount of snow decreases. This allows us to better see the rock from which the mountain range is formed.
Everest formation
Mount Everest is composed of several folded layers of sedimentary and metamorphic rocks that are almost permanently covered by ice and snow, especially in the upper layers. These rocks have been deposited over many years. Discussing the formation of this peak requires discussing the entire formation of the Himalayan mountain range. We go back to the late Paleozoic and early Mesozoic eras , when the supercontinent known as Pangaea was the only landmass on the planet.
Approximately 180 million years ago, the surface of this continent began to fragment as a result of the planet's internal movements . Two large landmasses emerged, known as Laurasia and Gondwana. From this perspective, we see how the Indian subcontinent was separated from Asia. It began to move northward until it collided with Asia, an event that caused the subduction of the Indian subcontinent. The sinking of one subcontinent beneath the other was primarily due to differences in pressure and temperature, which caused the Earth's crust to fold and form the Himalayan mountain range. We know that Mount Everest is approximately 60 million years old.
Flora and fauna
It's not only an attraction for climbers and adventurers, but also a cradle of great biodiversity. Because of the reduction in temperature and atmospheric pressure at the summit of Everest, many animal and plant species cannot survive there. Only a few animals are able to remain on the surface, and even then, with significant limitations. Yaks are one example. They have large lungs that allow them to survive at altitudes of up to 6.000 meters. On the other hand, there are some bird species, such as the yellow-billed chough, that can fly up to 8.000 meters.
Some of the animals that can survive in these places are the red pandas, the Himalayan black bears, the snow leopard, some species of spiders, vultures and some pikas. The latter only go to take refuge in the mountains at certain times of the year.
As for the flora, it is less diverse to a point on some rocks we can see mosses, although from 4876 meters in height, you can only find some lichens and plants that form cushions. Above 5600 meters of altitude there is no vegetation at all.
I hope that with this information you can learn more about Everest and its characteristics.
