What will happen if you dig up the earth and jump in? It makes me sweat.

In daily life, when describing a person's arrogance and ignorance, we often say, "I really don't know how small it is!" " Then the problem is coming. Do we know how high and thick the sky is? This refers to heaven and earth in the physical sense. Throughout the ages, human beings have an infinite spirit of exploring the unknown. 1On July 20th, 969, Armstrong landed on the moon successfully, leaving human footprints on the moon. Since then, "How high is the sky" has been continuously measured by human beings.

Nowadays, while developing the space industry, mankind has also begun to cast its curious eyes on the interior of the earth. So what is the interior of the earth like? If you dig down from the surface, will the soil be dug through?

One day, looking at the land under my feet, it occurred to me that I wanted to know what else was underground besides soil, so I found a shovel and began to dig down.

It didn't take long to dig a spider's nest. This spider is called the cave tarantula, which is highly toxic and lives in a cave about 0.4 meters underground. If you are accidentally bitten, please seek medical attention immediately.

Keep digging, the depth of the pit is already 1 m. If you want to measure the surface temperature, then this is the standard depth.

After digging for another two hours, I stood at the bottom of the pit with all my strength. At this time, the depth of the pit reached 2 meters, the standard depth of the Olympic swimming pool was 2 meters, and the traditional burial depth was 2 meters. Although cremation is more advocated now, in the saying that burial is safe, the depth of two meters can effectively avoid plague, which is also the wisdom of our ancestors.

I can't dig any more, but in order to satisfy my curiosity, I drove the excavator and continued to explore with the help of the excavator. Before long, a nest of ants appeared in the pit, which turned out to be an ant cave. Ants usually build caves about 3 meters underground.

After enjoying the structure of the ant hole for a while, I continued to dig, and I dug 4 meters underground. I remember that the tomb of Egyptian Pharaoh Tutankhamun was 4 meters underground. It is said that there is a sentence on his epitaph: If anyone dares to disturb the peace of Pharaoh, he will face death. Fortunately, I didn't go to Egypt to dig.

Not much to say, continue to dig down, 5 meters underground, just the depth of the former site of Bohai Banknote Printing Factory. Bohai Banknote Printing Factory affiliated to Beihai Bank was established in the early days of the Anti-Japanese War. It experienced two difficult historical stages: War of Resistance against Japanese Aggression and the War of Liberation. In that war-torn era, it is conceivable to build such a large-scale underground banknote printing factory.

Digging further down, it is 6 meters underground, which is about equal to the burial depth of the Terracotta Warriors and Horses of Qin Shihuang Mausoleum. Terracotta Warriors and Horses are the eighth wonder of the world. 1974 was excavated in Xi 'an, Shaanxi Province, and 1987 was listed in the World Heritage List. More than 200 foreign heads of state and government have visited here successively. Today, the Terracotta Warriors are a historical card, telling the world the glorious history of ancient China.

After lamenting the magic of the Terracotta Warriors, I dug 7 meters underground, and then the excavator could do nothing. At this time, I remembered another tool that appeared in the book "Notes on Grave Robbery", Luoyang shovel. Luoyang shovel was first used to rob tombs, and later it gradually became a common drilling tool in archaeological operations.

With the help of this tool, it was dug to a depth of 8 meters underground. When our ordnance unit detects underground mines, the maximum underground depth that can be detected by the metal detector is 8 meters.

9 meters underground, this is the depth at which Xingyi site was found.

Underground 10 meter is the depth of the Great Wall of Vietnam and the deepest distance that Luoyang shovel can dig. Digging deeper is beyond my ability, so you can see the following scenes from the resources.

15 meters underground, there is a letter from Einstein to mankind after 5000 years. 1938 In August, Einstein received a phone call from then-American President Roosevelt.

After the letter was written, the American government buried it in a "time capsule" with 35 daily necessities such as telephones and razors, at a depth of 15 meters underground.

Because the mine is too deep, if a small plane flies over, it may be sucked in by the powerful airflow generated inside the mine.

700 meters underground is the depth of copper and gold mine in San Jose, Chile. 20 10 On August 5, 33 absenteeism workers were trapped 700 meters underground due to a landslide accident.

My conclusion

So far, people know only 0.2% about the earth under their feet. Some people say that fear comes from the unknown, but at the same time, curiosity also comes from the unknown. Our exploration of this blue planet is not only to satisfy our curiosity, but also to live in harmony with nature. I believe that one day, the earth will unveil the mystery for us.
