How many mysteries are there in the history of the world? What are the events of the world s unsolve

American scientists have recently released 10 unsolved mysteries about the Earth.

1. How did the Earth and other planets form?

Scientists still don't know how and why planets form such unique shapes, and why only our rocky Earth has life.

2. What happened to the Earth during its "dark ages", the first 500 million years after its formation?

Understanding the early evolution of the Earth will explain the evolution of the atmosphere and oceans. But here's the difficulty: very few rocks from that time have been preserved, which means there is very little concrete evidence.

3. How does life originate?

In addition to rocks and ores, scientists are also exploring Mars, which has an earlier sedimentary record older than the oldest rocks on Earth.

4. How does the inner workings of the Earth? And how does it affect the Earth's surface?

5. Why does the earth have plate structures and continents?

Scientists want to know why the Earth has plates and continues to move, and how plate theory connects the vast amounts of water, continents, oceans, and life.

6. How does the Earth respond to the control exerted by the properties of materials?

7. What causes climate change? How is the climate changing?

An in-depth study of the history of the Earth's climate will help** the intensity and consequences of climate change today.

8. How did life form on Earth? How did life form on Earth?

The interaction of geology and biology is key to understanding the processes by which life injected oxygen into the atmosphere, mass extinctions, and biological evolution.

9. Can volcanic eruptions and their aftermath be possible?

Scientists don't yet know how **** and volcanic eruptions begin and end, or how magma moves beneath the surface.

10. How does magma flow and transport affect the human environment?

These questions were asked by experts from the U.S. Department of Energy, the American Academy of Sciences, the U.S. Geological Survey, and NASA.

Loch Ness Monster.

The Loch Ness Monster is one of the most mysterious and fascinating mysteries on Earth.

Loch Ness is located in the Grand Canyon in the northern part of the Scottish Plateau in the United Kingdom, with a length of 39 kilometers and a width of kilometers. The area is not large, but it is deep. The average depth is 200 meters, with the deepest being 293 meters.

The lake does not freeze all year round, with steep banks and dense woods. There is a river at the northern end of the lake that communicates with the North Sea.

The earliest records of water monsters date back to 565 AD, when the Irish missionary St. Columber and his servants were swimming in a lake, and the water monster suddenly attacked the servants, but thanks to the timely rescue of the priests, the servants swam back to shore and saved their lives, and since then, there have been more than 10,000 reports of the appearance of water monsters in more than ten centuries. But at the time, people did not believe it, thinking that it was nothing more than an ancient legend or nonsense.

It wasn't until April 1934 that Wilson, a London doctor, passed by Loch Ness and spotted a water monster swimming in the lake. Wilson hurriedly took a picture of the water monster with his camera, although it was not very clear, but it still clearly showed the characteristics of the water monster: the long neck and flat head did not look like any kind of aquatic animal at all, but very much like the huge reptile plesiosaur that went extinct more than 70 million years ago.

Plesiosaurus is a huge aquatic reptile that lived from more than 100 million years ago to more than 70 million years ago, and is also a distant relative of dinosaurs. With an elongated neck, oval body, and long tail, and sharp teeth in its mouth, it fed on fish and was the overlord of the Mesozoic seas.

If the Loch Ness Monster is indeed a plesiosaur, it is undoubtedly an extremely valuable surviving prehistoric animal, and this discovery will also have an important place in zoology.

Pyramids of Egypt The pyramids of Egypt are known as the "Seven Wonders" of the world, the most spectacular of which is the Pyramid of Khufu, built more than 2700 BC. The tower is high meters, the bottom edge is long meters, covers an area of about 52,900 square meters, the total weight is about tons, the tower body is made of 2.3 million boulders with an average weight of 10 tons each, and there is no paste between the stone and the use.

Mystery 1: How can it be so accurate? The pyramids of Egypt were built on the meridian line, dividing the earth's land and sea into equal parts.

There is no adhesive between each stone of about ten tons, but the dust cannot be inserted into the stone cracks with a thin blade. The four base edges of the pyramids differ in length by less than one thousandth (20 cm). Each cone angle is the most stable 52°.

How did the ancient Egyptians do it 4,500 years ago?

<> "Stonehenge. Located in London, England, Stonehenge is one of the most famous and mysterious prehistoric sites in the British Isles. The scale and difficulty of Stonehenge's construction was unbelievable to the people of the time, so there are many theories about its builder to this day.

In addition, the role of Stonehenge has also been asked very much.

Antarctic ice-free lake.

Antarctica, known as the "White Continent", is almost entirely covered by ice, with temperatures ranging from minus 50 to 60. According to common sense, the water freezes into thick ice at this temperature, but strangely enough there is a freezing-free lake. Although there are many conjectures put forward by Nano scientists, there is still no convincing explanation.

Uluru Boulder.

Uluru, located in Australia, is an absolute wonder of the world, some say it fell from space hundreds of millions of years ago, others say it is a deep-sea sediment ......It is beautiful and mysterious, taking on different colors in different seasons and even at different times of the day.

Pyramid. There are so many mysteries surrounding the pyramid that remain unsolved, because the structure condenses too much of the wisdom of the ancient Egyptians. According to relevant research, the pyramid contains many mathematical principles, which has led to the mystery of its builder.

In addition, there are many mysteries about the structure and function of the pyramids.
