Why are there so many pits lately, and what are pits?

In the first half of this year, the drought in the south and the excessive use of groundwater led to the relaxation and subsidence of the surface soil layer, and the appearance of pits in Guangxi is related to its soil quality.

The people upstairs are all joking about it, there are many unsolved mysteries of nature, and the crop circle is one of them.

This kind of thing should be investigated by the relevant authorities, not just unfounded speculation like yours, and it may just be a geological problem.

As for 2012, even the Mayan descendants say that it is nonsense from Westerners, and the so-called 2012 refers to the evolution of the human mind, which has improved a lot in all aspects.

The people I hate the most are.

Quite simply, because earthlings overexploit the resources on the planet. 2012 is here. The retribution of humanity has come. 2012 The whole earth is perished. After that, the rats kept going in... Multiply.

The earth is constantly moving in most areas for mining, oil.

Water resources are dwindling.

The earth is about to be "hollowed out".

So it needs to be made up.

I'm telling you, that's how the end of the world came by.

Recently, it is the rainy season, and the rainwater seeps into the soil layer and loosens the soil.

The Earth's internal rock formations are cold and shrinking, causing eureal air bubbles to appear in the rock formations. The movement of the earth's crust causes the bubbles to burst, causing the ground to collapse in a circle. The pits are mostly circular and have neat edges, so that the various formations can be clearly distinguished.

Therefore, it cannot be caused by rainwater erosion or imperfect drainage facilities. It should be a series of results caused by changes in the interior of the earth's crust.

If it goes on like this, even if 2012 doesn't come, I guess 2022 or 2032 will be dead.

In this way, humanity destroyed our mother (the earth). I'm 25 years old now, if I could live again.

10 years, 20 years, that's pretty much it.

The small ones are usually mine collapses, or they are washed away by rain, and the large ones are generally karst.

You can't see it, everyone who watched 2012 knows it. That's the precursor. The earth's oil is drained.

It's like human blood is drained, oil is the blood of the earth, and the earth is a living organism, so aside, there are many, many strange things going on. If you don't believe me, just look at it.

What the Mayans described as a 3,600-year cycle of planet X, which gradually approaches the Sun and the Earth, gradually changes the Earth's gravitational and magnetic fields, is difficult to predict

Because people are pumping too much groundwater.

Oil extraction, coal mining, groundwater extraction, the ground is empty, can it not collapse.

2012 Earth Destruction Prepare to die.

Please don't think anything of 2012 is just a movie.

I don't know all at once I know about Lazar!

I don't know, I'm about this, thank you.

The pits are as follows:When I entered the village, I didn't see a house, and I couldn't hear a sound. "The pit, also known as the "Tianjing kiln", is an underground kiln. The cave courtyards are connected together, which is a pit courtyard.

Introduction:

The pit courtyard is also called the Tianjing Courtyard, the Dikeng Courtyard, the local people call it "Tianjing Courtyard", "Diyin Pit", "Diyao", it is the remnant of the ancient people's cave dwelling method, known as the "underground courtyard" in northern China, and it is said to have a history of about 4,000 years.

2007 Shaanxi County, Henan.

It was named China Pit Kiln Institute by the Chinese People's Association.

Home of culture. In 2011, the "pit courtyard construction technique" was selected into the third batch of national intangible cultural heritage list.

The pit is also known as the sinkhole, which refers to the extraordinary spatial and morphological characteristics such as huge volume, steep and encircled rock wall, deep well-shaped or barrel-shaped contour, etc., developed in the soluble rock layer with particularly huge thickness and deep groundwater level, from the underground to the ground, the average width and depth are greater than 100 meters, and the bottom is connected with the underground river A kind of extra-large karst negative terrain.

The causes of sinkholes are mostly divided into two kinds, most of them are collapse types such as Guangxi Leye sinkhole group, etc., and rare are erosion types such as Chongqing Wulong Houping erosion sinkhole group.

Pit refers to excavation with a bottom area of 20m2 (excluding widening of the working face). If the area at the bottom of the pit is more than 20m2 (excluding widening the working face), it shall be calculated according to the flat foundation.

There are multiple factors in the formation of giant craters, which can be broadly summarized as human activities (underground mining, etc.) and natural movements (crustal movements, etc.).

Many of the huge craters in various parts of China are individual phenomena, and they cannot be summarized according to the size, distribution, layer characteristics, etc., and have no reference value.

Guatemala's kind of crater is the kind that needs to be analyzed by geologists. In China, Shanxi and other coal-intensive areas and areas with very different changes in groundwater levels, as well as highways (often overloaded) and underground foundation changes, are the most likely to produce the so-called "giant pits". Mostly the effects of human activities, which lead to a drop in the water table combined with geological changes to produce a special form of damage to the surface!
