How the earth was born, how the earth was born

How was the Earth born?

The birth of the earth is like this: the original universe was a high-temperature, high-energy, high-density substance, and due to the large **, various planets were produced. At that moment, those planets were all hot and liquid, and also due to the action of surface tension, they were all round.

After hundreds of billions of years of cooling, the temperature on the surface of some planets gradually decreased, and then proteins were slowly produced, and life was born, and this planet is the Earth. In the various movements that followed, there was no reason to change it to other shapes, so it has always been in the circle until now.

4.6 billion years ago, the material of the solar nebula was gravitationally gathered into a clump and distributed in the orbit of the solar system, the third being the early Earth. As a result of the explosion of red giants and larger stars in other galaxies, other heavy elements have appeared on Earth. One of the longs is iron.

When the earth's mass increases, the iron element sinks, due to the huge pressure and temperature increase, the center of the earth melts at high temperature, becoming an iron-nickel core, and the lithophilic elements with small specific gravity float up to form the mantle and crust, and the lighter liquid and gaseous components spill over the surface through volcanic eruptions to form the original hydrosphere and atmosphere.

Here's how the earth was born:

After the formation of the nebula disk, due to the action of gravity and the instability of gravity, the material in the nebula disk, including the dust layer, was formed due to collision accretion to form many protoasteroids or stars, and after gradual evolution, they gathered into planets, and the earth was born in it.

The Earth originated from the primordial solar nebula 4.6 billion years ago. The microasteroids that form the Earth originate from the remaining lumps of gas, ice particles, and dust with a diameter of 1 to 10 kilometers after accretion and collapse. These rough manuscripts grew over 10 million to 20 million years before they eventually formed the original Earth.

The nascent Earth's surface is an "ocean" of magma.

The Earth rotates from west to east while revolving around the Sun. There are 100 million. It originated from the pre-paedne clouds of the primordial solar star 100 million years ago.

Earth is the third planet in the solar system from the inside to the outside, and it is also the terrestrial planet with the largest diameter, mass and density in the solar system, about 100 million kilometers from the sun.

The interior of the earth is divided into the core, mantle, and crustal structure, and there are hydrospheres, atmospheres, and magnetic fields outside the surface.
