How do people know about the science of the earth? Are you sure that s correct?

It was in 1522 that humans began to recognize the Earth as a sphere. Magellan's circumnavigation of the globe not only opened up new routes, but also proved that the Earth was round through his expeditionary fleet.

It was recognized more than a thousand years ago that the Earth was a sphere, mainly through Magellan's fleet, which first circumnavigated.

Around the thirteenth and fourteenth centuries developed the Earth was a sphere. The Portuguese navigator Magellan believed that the Earth was a sphere, so he circumnavigated the globe and finally returned to the original point to prove that the Earth was a sphere.

People have come to realize that the earth is a sphere since the age of sailing, and when Magellan sailed, the ship was slowly revealed in people's field of vision in the sea, proving that the earth is a sphere.

With the development of human social productivity, science and technology, and navigational transportation, the scope of people's activities has gradually expanded, the field of vision has become broader, and the spherical concept of the earth has gradually formed. In particular, Magellan completed the first circumnavigation of the world by man, proving to people with irrefutable facts that the earth is round and the world's oceans are a whole.

1. The 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. The radius of the equator is kilometers, and its size ranks fifth among the planets of the solar system. The Earth has an atmosphere and a magnetic field, 71% of the surface is covered by water, and the rest is land, making it a blue planet.

2. The earth is home to millions of creatures, including human beings, and it is also the only celestial body in the universe known to mankind that has life. The Earth is 4.5 billion years old, and there is a natural satellite Moon, which revolves around the Earth in a celestial cycle, while the Earth rotates from west to east, rotates in a cycle of nearly 24 hours and orbits the Sun in a one-year cycle.

3. There are cores, mantles and crust structures inside the earth, and hydrosphere, atmosphere and magnetic fields outside the earth.

The results obtained by scientists through research are to be awaited, not final, and it takes a long time for a research result to be verified.

Not all of what scientists say is true. There are many different theories about the formation of the Earth, and scientists are constantly studying and experimenting with it.

The Earth was formed after a great event in the universe hundreds of thousands of years ago, and scientists are not all right, but most of them are right.

The question of how the earth came to be is pure, and scientists have given all kinds of speculations and directions for so many years, but in fact there is no real evidence to confirm it. The earth has exceeded 1 billion lives since its appearance, and the existence of human beings is actually very short compared to the earth, so in this case, the question of how the earth was formed has always been a variety of speculations by scientists, rather than substantial evidence to prove how the earth was formed. Therefore, netizens can choose to believe some of the scientists' remarks, but it does not mean that what they say is right.

Each has its own reasoning on this issue, different scientists and different scientific circles have given different ideas, such as the universe or molecular condensation, but these statements have their own truths, and there is no way to convince each other. Therefore, there is really no standard answer to this kind of question, and it is entirely a matter of free mind to believe which statement to believe. As for the cause of the formation of the earth, it may be possible to overturn the previous conclusions in the course of future research, but it is not possible to confirm it.

It's too long, after all, the Earth has existed for too long, and there is no substantial evidence to deduce how it came to be. Scientists have also expressed that the Earth is likely to be older than the Sun, so there is no need to fix the mind in a very small area. Studying the earth and the universe is a very big situation in itself, so we must open up our own pattern and consider these things with perfect thinking.

There is no definite answer, and in fact, there is no way to confirm whether there is any life on other planets other than the earth. There are no definite answers to the question of the existence of other life forms and how the earth was formed, so scientists will need to continue to study in the coming time, so that the truth of these things can be gradually discovered.

Scientists are not always right, because there are many theories about the formation of the earth, and the earth is so mysterious.

Personally, I feel that what scientists say is right, because scientists can predict, and they themselves predict the formation of the earth based on certain factors.

Not all of what the scientific hail masters say is right, because scientists are now modeling and hypothesizing based on the data they have now, so we still need to continue to explore the reasons why the earth is really forming, because there are many places on the earth, and we have not yet figured out the specific structure.

There are many scientists who have come to the conclusion that the earth and the sun are actually dead stars, and finally it took tens of millions of years to slowly transform into what they are today, but with the continuous development of science and technology, scientists have gradually learned from the analysis of the composition of the sun and the earth that the formation of the two is actually related to the dead star, and here and the earth and the sun are dead stars, there is still a very big difference between the two. Whether it is the earth or the sun, the most important components are hydrogen and helium, the reason why the sun can shine is because these two elements are inconclusively nuclear fusion reactions, then these planets in the beginning of the formation of the sky, it is by these elements continue to react and accumulate to form the earth and the sun, when the asteroid is formed at the beginning of the formation, the more material accumulated, the greater the probability of becoming a star, if the accumulation of less material, Then it is most likely that a planet will form, which is why the Sun will be a star and the Earth will only be a planet.
