2. The highest point on the earth is not Mount Everest
The highest point on earthis not Mount Everest.
Mount Everest is indeed the highest mountain in the world, with an elevation of 29035 feet (about 8849, 87 meters). But because the earth is not round, the peaks near the equator are actually closer to the starry sky, so the highest point of the earth is theoretically Mount Chimborazo in Ecuador. Although its altitude is only 6272 meters, it is 2400 meters above Mount Everest.
3. The distance between the earth and the moon gradually increases
The distance between the earth and the moon gradually increases.
After 25 years of observational research by scientists, it has been found that the moon ’s orbit is gradually expanding, which means that the moon is gradually moving away from us. Scientists have calculated that the radius of the moon's orbit around the earth increases by 4 centimeters every year.
4. Mankind has been extinct and there are only more than 2,000 people left in the world
According to the latest research, only 2,000 people were left in the population of 70,000 years ago. This latest study mainly detected human DNA (through maternally inherited offspring) and found that between 90,000 and 150,000 years ago, the Hoy and Sann people in southern Africa were separated from other humans. This latest study revealed some important events in human history.
5. Some people are "charging" the earth
Some people are "charging" the earth.
In 1917, scientists discovered that the surface of the earth has negative electricity, but why the earth is charged, and what is the "charger" of the earth, but no one can say clearly.
The study found that on sunny days in some areas, an electric current is generated between the earth and the air, with an intensity of 15O0 amps. But because the earth is too huge, the current will soon disappear, but this kind of current must be caused by some role as a "charger". But so far scientists have not yet concluded the identity of this "charger".
6. The gravity on the surface of the earth is not exactly the same
In the coastal areas of India, people will be lighter in weight, but in the southern Pacific Ocean, they will be heavier. The reason for this difference is still under study. The GRACE Gemini satellite launched by NASA in 2002 is now measuring the earth's gravity field in detail, which may help scientists find the cause of this gravitational gap.
7. Earth's atmosphere is "escaping" every day
According to research, some gas molecules on the edge of the Earth's atmosphere will escape from the gravitational force of the Earth and "escape" into the universe beyond the Earth's atmosphere. This process is very slow, but has been in progress.
And the lighter hydrogen molecules are easy to fly to the outside of the atmosphere because of their light weight, so the atmosphere becomes suitable for living creatures. However, no one needs to worry that the hydrogen element will disappear around the earth one day, because hydrogen can combine with oxygen to form H2O molecules, so it becomes very stable and will not easily "escape" out of the atmosphere.
8. The atmosphere of the earth will also fluctuate
As we all know, the effect of the rising tide of the water body on the earth is closely related to the gravity of the moon, but few people know that the gravity of the moon will also have a fluctuation effect on the earth's atmosphere. The theory points out that the influence of the moon's gravity on the Earth's atmosphere is more obvious near the tropics, making the atmosphere here thinner, but the effect of this effect is much smaller than the effect on the earth's water bodies.
9. The magnetic fields of the two poles of the earth are interchanged many times.
In history, the magnetism of the earth's poles has been exchanged more than once. The north magnetic pole was first discovered in 1831, but in 1904, it was discovered that it had moved 50 kilometers. But why the magnetic poles are deflected or interchanged is still a mystery.
10. The speed of the earth is accelerating

According to research by scientists, the speed of the earth's rotation is accelerating unconsciously. The time for the earth to rotate one week has been several milliseconds shorter than in the past. Scientists believe that the angular velocity of the earth is constantly increasing, but the specific reason for the change is unclear. However, observations have shown that the earth moves at its slowest speed between January and February.
11. The earth once produced a free oscillation in the direction of the earth's rotation, known as the Chandler oscillation
In 1891, American astronomers discovered that the Earth's rotation angle was deflected by 1/3600 seconds in 433 days. That is to say, the two poles of the Earth deviated from their original positions by 3-15 meters. In 2006, scientists discovered that the Earth's Chandler shock has ceased, but the reasons for the occurrence and stop of this shock have been unknown.
12. One day is not 24 hours
One day is not 24 hours.
This green home rotates once around the earth axis, and the actual time is 23: 56: 4. This is the so-called "solar day", which is the time between two suns at the same location on the meridian. There is a difference of up to 16 minutes at this time every year.
13. The Earth is the only planet with a plate structure

Scientists generally believe that the earth is composed of 7 important crustal plates, which move about 10 cm in different directions every year to form various landforms such as mountains and valleys. At the same time, it will cause natural phenomena such as volcanoes and earthquakes. Although these activities seem to bring disaster, but also make the element of living organisms-"carbon" is recycled and recycled.
14. The earth once had a sister planet named "Theia"
Some scientists believe that there was once a sister planet named "Theia" in the orbit of the earth. Similar to the size of Mars, it runs at a 60-degree angle in front of or behind us. On the afternoon of one day 4.5 billion years ago, Theia suddenly hit the earth, most of it was absorbed by the earth.
15. More than 90% of the ocean belongs to the unknown world
Although humans have explored space, the moon, and Mars, but for the vast ocean. The area that humans have studied is less than 10%. The ocean includes 97% water and 99% habitat area. Although more than 210,000 marine organisms have been identified, there may be 25 million species to be studied.
16. The earth's lowest temperature reaches minus 128, 6 degrees Fahrenheit (minus 89, 22 degrees Celsius)
The lowest temperature of the earth is minus 128, 6 degrees Fahrenheit (minus 89, 22 degrees Celsius).
On July 21, 1983, the Vosto station in Antarctica Russia recorded the lowest temperature of the earth at minus 89.2 degrees Celsius, and the highest temperature of the earth was recorded on September 13, 1922 in El Azizia, Libya. 57.8 degrees Celsius.
