How did the earth come to be in the earliest places, and how did the earth come about? When was the

The solar system is a nebula, in the cosmic region very close to the solar system at that time, there was a large star death event, the mass of this star is at least 8 times more than the sun, before the death, this late star, that is, the supernova had a violent instantaneous **, this instantaneous big ** made the density of the nebula where the solar system is located changed, the collapse of this region began, followed by the change of gravity, a large number of movements and collisions began, and the final result was the formation of a huge sun, It has a very high internal temperature, with a core temperature of up to 15 million degrees. The rest of the various materials were thrown into space, and because of the huge mass of the sun, they began to move around the sun and slowly began to coalesce together to form planets.

At the beginning of the formation of the solar system, the Earth began to form, a slowly cooling, reddish magma-filled planet, which was not much different from the surrounding Mars, Venus and Mercury, but at this time the Earth suffered a heavy blow, an asteroid with a mass of about 10% of the Earth hit the Earth strongly, part of it merged with the Earth, and the other part became the Earth's satellite Moon. The impact between the earth and asteroids has been happening for more than 4 billion years, and the arrival of these asteroids has brought not only trauma to the earth, but also a variety of colorful elements.

When the Earth first took shape, it was a lava planet with no land, with a temperature of more than 1,200 degrees Celsius, but no oxygen, and the main gases were carbon dioxide, nitrogen, and methane. You can imagine what the magma sea was like, and Hell was weaker than the earth at that time. However, as the planet cooled down, a lot of heat was squeezed out, clouds were formed, and then the longest rainfall on Earth's history, thousands of years of heavy rainfall, flooded the relatively low-lying areas of the Earth, and became the first ocean.

However, the rain is only half of the seawater, and it is assumed that half of the water comes from outer space. Comets made of rock and ice crashed into the Earth's surface and brought a lot of water to the Earth, and since then, the blue planet has been created.

The Earth is a star created when the constellation Andromeda collided with the Milky Way, and the Earth was formed 100 billion years ago, and life was born over time.

The earth is dust floating in space, after 4.5 billion existence, these dust and some gases from the ancient star ** continue to develop, the outer layer of the earth gradually cooled and solidified into solids, forming the current earth; The Earth was formed more than 4.5 billion years ago.

The Earth was formed about 4.5 billion years ago; This rocky planet, originally just dust floating in space, originated from the large ** of the huge ancient core at the end of its life, and was roughly formed by absorbing technology in the long years of change.

The Earth was formed more than 300 billion years ago by gathering a lot of heat and some debris from the sun.

It may have been created by a large **. Many scientists say that the Earth was created 50 million years after the formation of the solar system.

How old is the earth, there are various theories in ancient and modern times. In ancient China, there was a saying that "from the opening of the Pangu clan to the Western Zhou Dynasty, where 3.26 million years are long." What's even more ridiculous is that there was an Archbishop in England named Remember Schell, who in 1654 testified:

The earth was created by God on October 26, 4004 BC at GM. Of course, no one believes this nonsense. Later, scientists used various methods to make calculations:

But the results are not the same. Astronomers believe that the time of formation of the earth should be about the same as that of meteorites, and they believe that the age of the earth should be no less than 4.5 billion years, based on the age of meteorites between 4,548 million years. In 1969, the American Apollo 11 landed on the moon and measured the age of the moon to be 4.6 billion years based on the lunar samples brought back.

As a result, most scientists believe that the Earth should be "the same as the Moon". At a seminar held in the United States and the Soviet Union at the end of February 1978, the Bernaki Institute of the Soviet Union introduced that the earliest rocks formed on the earth had recently been discovered in Ukraine.

It was determined by the radioisotope rock dating method, and it was confirmed that it was formed hundreds of millions of years ago. This further suggests that the primordial Earth was once covered by molten magma, and that about 4 billion years ago, it gradually began to cool and solidify, forming a landmass. Two years ago, Japanese scientists suggested that the Earth may have been formed 6o billion years ago.

They analysed a piece of diamond from Zaire. And measure the half-degree ratio of the two elements of this diamond potassium 40 and manifest 40, and then according to the half-life of the radioactive element potassium 40, calculate the generation age of this diamond about 6 billion years ago.
