You know how the Earth came out

I don't know how it came out, but I want to know how he came to be and when he was going to be ???

About 4.5 billion years ago, some gases, dust, ice particles and other materials gathered together to gradually form the prototype of the earth, which is only 1,000 meters in size, which is very small compared to the vast universe.

But it was this "little earth" that kept rotating, absorbing and gathering other materials around it, and after tens of millions of years of accumulation, it gradually formed the size of the current earth, but the earth at that time was completely different from the earth now.

It is said that the universe collapsed greatly

Yes, the Earth is basically a planet that is approximately spherical in shape. But it is not a fully spherical body, but slightly flattened, which is due to the centrifugal force generated by the rotation of the Earth. The diameter of the Earth is about 12,700 kilometers, the circumference of the equator is about 40,000 kilometers, and the circumference of the polar axis is about 39,480 kilometers.

Because its size and mass have an effect on its gravitational field and rotation period, the shape of the Earth is crucial, and it is also an important factor that astronomers must consider when studying the universe and geophysics.

The Earth is an elliptical sphere, and by fitting calibrated charts and projection data, a globe can be drawn with the center as the origin. The Earth can be divided into three layers from the inside out, which are the crust, mantle, and core. The earth's crust is the thinnest layer of the Earth's surface and is made up of various types of rocks, mainly of elements such as iron and manganese.

The mantle is located beneath the earth's crust and is made up of various types of rocks and minerals, with an average temperature of about 4,000 degrees Celsius. The Earth's core, the innermost layer of the Earth, is made up of heavy elements such as iron and nickel, and the internal pressure is very high, reaching millions of atmospheres. The surface area of the earth is about 100 million square kilometers, of which about the land is water, and the ocean occupies about 71% of the earth's surface.

The inner circle of the earth is composed of the core, outer core, mantle and crust, of which the core is the innermost layer. The age of the earth is about 4.6 billion years, and it is still rotating and revolutionizing, while also shaping and reinventing itself. The earth is a planet for human survival and development, and its unique characteristics and evolutionary process have made it a stage for the birth and evolution of life.

Earth is a planet, the third closest planet in the solar system to the Sun and the only planet known to have life. The earth has a terrain and climate rich in species and diversity, and humans rely on the earth for survival necessities such as food, water, and oxygen.

The Earth is not completely round, but slightly ellipsoidal. This is because the rotation of the Earth causes centrifugal forces, i.e., the Earth's equator is more convex outwards than the poles. At the same time, there are some mountains and depressions on the earth, and these irregular terrain can also have a small impact on the shape of the earth.

The diameter of the Earth is about 12,742 kilometers, and the circumference of the equator is about 40,075 kilometers. The time it takes for the Earth to make one revolution is about 23 hours, 56 minutes and 4 seconds, and the time for one revolution is about days. The Earth's surface is covered by 70% of the oceans, with a land area of about 148,940,000 square kilometers.

Yes, the Earth is approximately spherical. Although there are many rolling mountains, rivers and oceans on the surface of the earth, the shape of the entire earth is an approximate sphere shaped by gravity and rotation. As early as the 4th century B.C., the ancient Greek scholar Aristotle had already put forward this conclusion.

Later, Copernicus, Galileo, Newton and others proved the approximate spherical shape of the earth through different methods and evidence.

Earth is the planet we live in, and it is the third closest planet in the solar system. Here are some common characteristics about the Earth:

1.Shape and size: The Earth is roughly oblate spherical and slightly oblate. It has an average diameter of about 12,742 kilometers and an equatorial circumference of about 40,075 kilometers.

2.Geographical features: The Earth's surface is covered by land and water.

Land includes continents and islands, which make up about 29% of the Earth's surface area and are mainly found in the Northern Hemisphere. The water area is mainly made up of oceans and oceans, which make up about 71% of the Earth's surface area. The earth also possesses many geographical features such as mountains, plains, rivers, and lakes.

3.Atmosphere: The Earth is surrounded by a layer of gas called the atmosphere, which is a mixture of nitrogen, oxygen, argon, carbon dioxide, etc. The atmosphere is essential to maintain the Earth's climate and the existence of life.

4.Rotation and Rotation of the Earth**Earth rotation refers to the rotation of the Earth around its own axis, and it takes about 24 hours to make one rotation, which is also the reason for our daily day-night cycle. The revolution of the earth refers to the movement of the earth around the sun, and the time of the year is the day.

5.Life exists: Earth is the only planet in the known universe where life has been found. Life forms on Earth include a wide variety of organisms such as animals, plants, and microorganisms.

These are just some of the basic features of the Earth, which has many other complex features such as geology, climate, and ecosystem that make up the Earth as we know it.

How much do you know about the Earth? Although humans have lived on this beautiful blue planet for more than 7 million years, the earth is like a mysterious gauze that makes it impossible to see what it really is. According to the results of geologists' study of strata, the earth has gone through 4.5 billion years since its birth, and what strange things have happened in this long time?

When the Mayan civilization is mentioned, the 2012 end of the world must come to mind. Although this was eventually confirmed as a rumor, it was surprising that the Maya were able to calculate what would happen thousands of years later.

Unfortunately, there are not many records of the Mayan civilization in ancient books, and before Columbus released the New World, this mysterious national civilization disappeared and disappeared.

In fact, in addition to being able to predict the time of the end of the world, the Mayans were also proficient in astronomy and geography, and made some speculations about what happened on the earth in the past, creating the Mayan calendar. Modern historians have examined the Mayan calendar and discovered an astonishing fact: the Earth has experienced five mass extinctions, and the creatures in the biosphere are now the sixth generation of the Earth's successors.

According to the Mayan calendar, the first five generations of "descendants" of the earth were: giants, dwarves, humans, elves, and dinosaurs. However, this human being is not the other human being, and they are very different from modern human civilization, and according to historians' speculation, human beings at that time were far superior to the present in terms of brain intelligence and social civilization.

To confirm this idea, historians put the moon on the ground. It is not an exaggeration to say that the moon is the most familiar planet to us, ancient people had emotional concerns about it, and modern astronauts have realized their dream of landing on the moon, but for this planet, we are also not clear, and even have doubts about its true identity. But if you think about the development of the earth, maybe everything becomes clear.

According to historians' speculation, the predecessor of the moon was just a hollow sphere, and the main constituent materials are not clear, and it was sent into space by the third generation of earth creatures, humans, and acted as a satellite. Later, with the advent of the third mass extinction crisis, advanced human civilization fell, and the moon was abandoned from the sky, and under the erosion of time, it became what it is today.

There may be many friends who are skeptical about this, but with the development of the archaeological industry in recent years, experts have discovered many ancient artifacts around the world, some of which are far beyond the current level of science and technology, all of which show the world how advanced human civilization was in ancient times.

The Mayans eventually disappeared, which has become a mystery, and many people speculate that their true identity is alien, but there is no real evidence to prove it. The Mayan calendar they left behind may reveal more mysteries.

When the sixth mass extinction will come, no one can determine the specific time, and I hope that the level of science and technology will continue to break through, and perhaps we can find a glimmer of vitality in the past history.
