When the comet collided with the Earth, it caused a big explosion. The entire Earth Star immediately turned into a sea of fire. The fire burned violently for about hundreds of thousands of years. It wasn't until about 4.6 billion years ago that the fire was finally extinguished as the combustible material burned out.

From this, it can be deduced that the predecessor of the earth may have been a star like the sun. During the Big Bang, the earth produced much more energy than the sun does today. (The Earth during the Big Bang, just like the Sun now.) It's just that the mass of the Earth is much smaller than the mass of the Sun. The energy emitted by it may also be much smaller than that of the sun. It can be inferred from this that perhaps in billions of years, after the solar energy is burned out, it may also become a planet. Moreover, if it undergoes some evolution, it is likely to become a planet suitable for life. (When the sun burns out, it most likely turns into a water ball.) Water is the origin of life. Thus it is possible to give rise to life. )

As the fire gradually extinguished, the primordial ocean, the product of the combustion, gradually covered the entire planet, and the primordial ocean gradually formed.

Since then, the Earth Star, which has undergone a drastic change, has taken on a new name and has become the planet on which the entire life world depends - the Earth.

After about a billion years, due to the movement of the earth and the fact that it was the beginning of the formation of the earth, the earth's crust was very unstable, so part of the land collapsed.

As the subsidence area continued to expand, the overwhelming water rushed to the subsidence area like a stormy wave, and the prototype of the four oceans gradually took shape.

With the further expansion of the subsidence area, and the fact that the water is permeable, a larger subsidence area has been formed. The raging waters of Pengbai rushed into the collapsed area even more like a stormy wave.

As the waters gradually returned to the sea, some of the original towering mountainous areas on the earth were first revealed, and the mountains were formed.

With the repeated retreat of the great waters. Some of the original plateau areas have also gradually been revealed. The plateau area was also gradually formed.

With the gradual receding of the flood water and the different soft nature of the geology, some originally flat areas were washed away into gully areas due to the erosion of large waters. (This is the true origin of Longevity.) )

As the flood waters dried up, the riverbed, where the flood had receded, formed the plains it is today. (For example, the Weihe Plain in Shaanxi Province and the Fenhe Plain in Shanxi Province were both riverbed areas in those years.) )

As the flood dried up further, only some remnants were left in the river area of that year, such as the Yellow River, the Wei River, and the Wei River, which eventually came into being.

Because the earth is originally a high and uneven ball, the floods in some low-lying areas have not receded due to the obstruction of the surrounding high mountains, and as a result, they have been retained and become some saltwater lakes. (Qinghai Lake in China, for example, may be a remnant of the waters that receded.) (The reason why Qinghai Lake is a saltwater lake may have something to do with this.) )

Through the above facts, it is clear that all the mountains and rivers in the world were formed in the same era and have a glorious history of more than 4 billion years.

Most of all the earth's landforms come from the great retreat of this flood. The subsequent changes, except for some man-made changes, are almost very small for the whole earth.

Flood shocks are the main cause of changes in the entire landscape. All other changes are insignificant compared to the planet as a whole.

I have seen many versions of the origin of the longevity plateau, and I have heard many beautiful legends about the origin of the longevity plateau. However, through my observation and evaluation of the article, I believe that none of these sources are feasible and reliable.

I believe that the longevity plateau should have been formed at the beginning of the earth more than 4 billion years ago, and it was by no means formed in the early stage of primitive society 3,400,000 years ago.

Anyone who has studied geography has been given the idea that the earth was once a water balloon. With this point of view, I believe that the main source of shaping longevity is formed by seawater erosion after the water recedes this time. (I once was on the edge of the ditch and carefully observed the trend and behavior of the ditch.) It is completely in line with the form of large water washing. Based on this, it is speculated that the cause of longevity was caused by heavy flooding. )

About four billion years ago, the whole earth was a world of water. As for how the earth's water comes from, there are different opinions at present, and no one can come up with specific evidence. However, according to my own speculation, the water on the earth should have been created from the beginning of the earth. The reason why the Earth is the only planet in the entire solar system with life. The reason for this is that it is different from other planets.

Water is the source of all life, and it is precisely because of the water on the earth that life is formed. Scientists have studied many options for human survival. But in the end, these plans are not realistic, and can only be laughed off.

About 4 billion years ago, the entire earth was a vast world covered by primeval oceans. Due to the movement of the earth and the fact that it was the beginning of the formation of the earth, the structure of the earth's crust was very unstable.

As a result, a series of changes in the earth's crust have been caused, and subsidence has been formed in some places. Add to that the reason why water is permeable. As a result, the overwhelming water rushed to the collapsed area like a stormy wave, and the rudiments of the ocean were formed.

As the flood waters receded, the mountainous areas that had been hidden in the floodwaters were first exposed to the ground, forming the current mountainous area.

As the flood waters receded repeatedly, some of the original high-altitude areas were gradually revealed. Due to the different softness of the geology, and the fact that these places may have been low in the first place, many gullies were formed after the flood washed away. (This is where the ditch comes from)

Most of all the earth's landforms come from the great retreat of this flood. The subsequent changes, apart from some man-made changes, were almost minimal.

As the flood waters gradually receded, the former river areas (such as the Weihe Plain) became the plains of today.

As the flood gradually dried up, some rivers such as the Yellow River, the Wei River, and the Wei River became the last remnants of the receding waters.

All of the above signs show that although the mountains and rivers formed at a slightly different time. But they were all born in the same era.

Things in the world are not mysterious, but some people make a mystery out of their own goals to show their abilities.

Everything in the world has a cause and an effect. One day, the mystery of the earth will be revealed. I sincerely beg for the early arrival of this day.

I was born in a small mountain village where my parents and fellow villagers lived. The beard is full of stories...... Singing this beautiful song reminds me of my own childhood.

My family lives in a village on the longevity plateau in Weinan, Shaanxi. Although the area of this village is not very large, it is also well-developed, rich in products, and has very advantageous geographical conditions.

The watered fields of Weibei Erhua are not as good as the longevity plateau of Weinan. When it comes to the name of Longevity, it is indeed well-known.

The plateau is located in the southeast of the bank of the Wei River in Linwei District, Weinan City, Shaanxi Province. The plateau area is located south of the Longhai Railway to the foothills of the Qinling Mountains. It is a loess plateau area cut by the middle and lower reaches of the Luhe River, the Linghe River and the Chishui River, with an altitude of 600-800 meters and a relative height of 150-330 meters, covering an area of 261.8 square kilometers, accounting for 20.9% of the total area of the whole area.

The longevity plateau area is high in the southeast and low in the northwest. In the southeast direction, Cheng terraced field, the top of the slope is relatively flat, the territory is vast, the products are abundant, and the harvest is guaranteed by drought and flood. There is a folk proverb that says: The crops of the longevity plateau are half harvested when the seedlings are harvested. Therefore, it is called the long harvest (longevity) plateau, and after a long time, it was changed to the longevity plateau.

Friends who have been to the longevity plateau probably know very well that there are some earthen ditches around the plateau, and these earthen ditches and ravines crisscross the entire plateau, washing the entire plateau to pieces.

Although my family does not live on the slope, because of one of my aunts, my family lives on the slope. Therefore, whenever it is the beginning of the year, when relatives and families greet each other, going to the ditch to play has become my first hobby.

I remember when I was a child, I often liked to read a novel called "100,000 Whys". I am particularly interested in the questions raised in the novel. In my spare time, I especially like to read science fiction novels. He has a strong interest in the things and natural scenes that happen around him. Therefore, whenever my cousin and I went to play by the ditch, we saw the scene in the slope, and driven by curiosity, I repeatedly pestered my cousin and asked how these ravines came to be.

In the face of my inquiry, my cousin could not tell the specific origin. It was just that it was dug by the hands of the ancestors, and a while it was said that it was caused by an earthquake.

As I get older, some ignorant words in the past have gradually turned into memories.

As I get older, I become more and more interested in these things. With these questions, plus what I have learned about geography. I boldly imagined the origin of a longevity plateau as a science fiction novel for everyone to enjoy. As for the truth of the matter, it is not known. Maybe in a few years, maybe it can be verified, the truth is often in the hands of a few.

The following is a fantasy novel that I envisioned. This novel only represents the author's own point of view, as for the real situation of the matter, it needs to be further investigated:

The Origin of Longevity (Science Fiction)

About 5 billion years ago, the entire solar system of the universe was not only orbiting the sun with nine planets, but also many asteroids, comets, and meteors revolving around the sun.
