There is a proverb in southern China that says, "The sea becomes a mulberry field", which is used as a metaphor for the earth-shaking changes in the scenery.
In the Himalayas, it is embodied and witnessed by people: from a blue sea to a towering mountain.
The world's tallest mountain, Mount Everest, with an altitude of 8,843.43 meters, can be called "heaven above the head", and it is also the abyss of the flying eagle that people yearn for.
It is unbelievable that such a short history of hundreds of millions of years can give birth to such a majestic mountain range.
So what is its life like compared to the tall Mount Everest in people's hearts?
1. Mount Everest: A giant from the ocean.
Although it was said that he was listening to the waves and hurrying, he didn't expect that listening to the waves would really grow into such an unattainable "strong man".
There is a proverb that reveals the history of Mount Everest: "A drop in the ocean", that is, Mount Everest is gradually raised on the basis of sediments submerged by the sea.
However, this proverb is somewhat inaccurate, Mount Everest is not accumulated from the bottom of the sea, but is a mountain squeezed out of the ocean.
The ocean, the earliest representative of the earth, can be traced back to the beginning of the heavens and the earth.
When liquid water first appeared on the earth, large seas and lakes were born, and later the atmosphere gradually stabilized, giving rise to oceans.
In this ocean of the Earth, a huge system of ocean currents has been formed - the Guttpana Ocean.
To the east of it, it is also home to the most powerful plate on Earth, the Indian Ocean Plate.
The eastern edge of the plate, with its solid material, is formed by the condensation of the ocean, so that when it cuts a path to the northwest, it will change dramatically in the course of its path.
Subsequently, the oceanic detrital material that has accumulated into the outer side of the Indian Ocean plate moves westward.
Over time, however, the Indian Ocean plate has moved northward, and the collision to the edge of the Indian Ocean is often formed by sediment accumulation.
When it collides with the Eurasian plate and pushes these sediments upwards, it naturally creates a majestic mountain.
Where this ocean meets the Indian Ocean plate is the Himalayas in the Tibet Autonomous Region on the mainland.
The area, known as the "Funeral of the Sea", has a complex geological structure, with mostly rocky surfaces and mountains of all sizes.
The Himalayas, on the other hand, are a large mountain range located on the southern edge of the Tibetan Plateau and are also known as the youngest mountain ranges in the world.
Originally, it was not a young mountain, but was formed 65 million years ago as a sea.
After that, the Indian Ocean plate began to squeeze towards the Eurasian plate, and as a result, the Himalayas slowly rose.
35 million years ago, the Himalayas continued to rise due to the movement of the Earth's tectonic plates, and at the same time, the temperature of the atmosphere also decreased by 12 degrees Celsius, resulting in today's severe cold weather in the second zero.
The cold combined with the impact of the Himalayas gradually reveals its smooth ridges, and when you walk above them, you can clearly feel the cold wind, as if you are standing on an iceberg.
And for such an ever-changing Himalaya, nature will give birth to all kinds of rare treasures, and even creatures connected to the afterlife.
2. Contains a biological mystery: ichthyosaur fossils.
After that, a new creature was formed on Earth: the ichthyosaur of the sea.
In the Himalayas, geologists have found fossils of this creature, so it is clear that the Himalayas were once conclusive evidence of the sea.
Although some mysteries about this creature have previously been discovered from ichthyosaur fossils: they feed on aquatic creatures and have terminal fins tens of meters long, until now the understanding of its ecosystem has not been perfect.
Even its names, "fish" and "dragon", are not the names of any creatures on Earth, so it is assumed that this creature was once a species that was born after a long period of evolution in nature.
However, they are affected by changes in the environment and are gradually swallowed up by the best period when the earth puts it in the refrigerator.
Despite this, people still found some clues from the fossils, and the dissection of the ichthyosaur fossil found that it contained many pathogenic bacteria in its body.
After a detailed description of these bacteria, it was found that they may be able to survive in water, including Salmonella adenosis and malodorous bacilli.
Comparing the previously extracted living environment with the pathogenic bacteria contained therein, it was found that they lived in a similar environment to pythons, and perhaps ichthyosaurs fed and stored from these bacteria.
On the other hand, geologists extracted nitrogen, carbon and other elements from ichthyosaur fossils, and the results showed that the existence of these elements is not in line with the current ecological environment, and follow-up research is needed.
Third, the years are long, and Everest is also changing.
Although the Himalayas have been formed for 65 million years, they are still changing, as the ancients said: "A mountain is still a mountain high", the so-called "fortunately the mountain, otherwise it is high, and it is unfortunate to be high in the mountain".
The changes in the Himalayas, like a great river going eastward, day and night, continue to carry away the river water, and eventually it will become unshapely.
Geologists have studied the changes in the Himalayas, and there is a view that the orogeny is not over.
20 million years ago, when the Himalayan peaks were raised, they reached a height of more than 9,000 meters.
Since then, after another 65 million years, today's Mount Everest is only 8,843.43 meters.
On average, Mount Everest grows 7 centimeters in height every 100 years, and at this rate, it will reach 7,500 meters in 65 million years.
However, in the opinion of geologists, the height of Mount Everest will not eventually exceed 15,000 meters, because after reaching this height, the mountain will gradually begin to collapse and can no longer bear its weight.
So what will happen to Mount Everest after this time?
This needs to look at the changes in the movement of the earth's plates, the movement of the earth's plates is constantly changing, only 2 centimeters per year, so the future of Mount Everest still needs to be speculated by scientists.
Still, geologists have not been unfounded, and they have shown that the future of Mount Everest may disappear into the sea, and most of the Earth's oceans are located in the Southern Hemisphere, so it can be inferred that Mount Everest sank into the sea of the Southern Hemisphere.
epilogue
Just like Mount Everest, majestic peaks are only a blink of an eye for the earth.
However, the ever-changing earth is pregnant with endless wonders, but also contains countless unknowns that need to be set aside one by one.
The changes of the earth are still continuing, and behind these changes is nothing more than the history of the evolution of the earth.
