Chapter 1370 How the Earth Was Formed

The blue cat is not a human, so Huang Chao will not sigh "Is this still a human?" Obviously, the cultivation of Chaowei Blue Cat starts bit by bit from daily life. Aunt Chicken's so-called "tackling game" gave Huang Chao an intuitive understanding of the combat effectiveness of this world.

Covered in flames, the blue cat ran away from the gate of the city screaming: "I'm scalding to death!" His movements were still alive and well, when he saw Huang Chao and Feifei who were watching, he said happily: "Brother Huanggou, Feifei, Come and help!"

Seeing his distressed look, Feifei shrugged her shoulders: "I really can't do anything about you." As Feifei said, she bowed forward, her orange tail spinning at high speed, like a helicopter's propeller, and he actually lifted herself off the ground, Fly low below the city walls.

Huang Chao has already seen that although the blue cat Feifei looks very bad, they are actually superheroes. So Huang Chao also let himself go, shaking his head and pointed ears, he jumped up to three feet high: "Brother Blue Cat, I will help you!"

Huang Chao's punch was so heavy that he hit the city wall with his punch. The city wall he hit with his fist swelled up at that time, and a wave of ripples spread from the position of Huang Chao's fist to all directions. It was because he hit an effect similar to earthquake waves...

"My hand hurts a little." Huang Chao thought awkwardly.

Naughty, Curry, and Fat Boy above were swept away by the ripples, and the three mice staggered to and fro, and finally circles of dizzy birds appeared on their heads, and they couldn't support themselves and fell to the ground.

The blue cat put his hands on his hips and laughed: "Hahaha, Brother Yellow Dog, you did a great job!"

Huang Chao picked up the blue cat, like picking up a strand of leeks from a vegetable field: "Brother Blue Cat, come on!"

Amidst the blue cat's frightened cry, he was thrown ten meters high by Huang Chao from under the city wall, and jumped directly on the three mice that couldn't escape. Seeing that he had caught the enemy, the blue cat immediately forgot about Huang Chao throwing him without saying hello. He laughed and said, "You rats just catch them. With me and Brother Huanggou here, you can't win."

Huang Chao rushed under the city wall, stomped his feet on the ground, and the dry land plucked green onions and flew two feet high. Then he turned a few somersaults in the air, not only did not land, but got higher and higher, until he fell to the top of the wall. The reason why it is so fancy is to conform to the mainstream of this world.

Naughty whispered: "Isn't this a dog meddling with a mouse?" What he said was so reasonable that Huang Chao and Lan Mao couldn't refute it.

Feifei finally dug through the city wall, and then found that the two elder brothers in her group had already stood on the top of the city and controlled the three members of the mouse team. I can only take out a gun from behind, point it at the three mice, and play my role: "Hand over the answer quickly."

That's right, they played for a long time, and they completed both the heaven and the earth. In fact, this is an interesting teaching game. They successfully tackled key problems and got the answer to "how the earth was formed".

Faced with Feifei's threat, the naughty trio showed disdainful expressions. The blue cat had already responded to this. He grabbed Fat Boy and carried him to the city wall by the two straps of his overalls amidst his exclamation. Foreigner: "If you don't tell me, I'll throw you down." With the big stick of the blue cat, he can definitely say it and do it.

Fatty immediately confessed: "Okay, okay, I'll give you the answer. You three robbers."

He walked towards a fortress on the city wall, knocked on the masonry wall, and the outer brick was removed, revealing the computer screen inside, which immediately displayed the teaching screen:

"How was the Earth formed?"

"The earth was born with the solar system: the solar system was born in the form of a huge and constantly rotating cloud of dust and gas. It is composed of hydrogen and helium produced by the big bang. Other elements synthesized inside the planet. Because of the rotation of the cloud, gravity and inertia press the cloud into a disk, which is perpendicular to its axis of rotation. Most of the mass is concentrated in the center and the earth begins to heat. At the same time, because of the gravity causing matter to condense around dust particles,

This caused the rest of the disk to begin to disintegrate into rings. Fine fragments collide with each other and form larger fragments. "

"The material that makes up the earth is concentrated in a zone about 150 million kilometers from the center. When the sun shrinks and heats up, nuclear fusion begins, and the resulting solar wind empties most of the disk that has not contracted and There are only a small amount of elements left in the matter that makes up the larger individual. After that, the heavier elements gather near the sun to form small, high-density stars (terrestrial planets); the lighter elements gather near the sun. Far away, large, low-density stars (Jupiter-like planets) are formed, and the Earth is the third closest planet to the Sun."

"The Earth had no oceans in the early Hadean epoch, and there was no oxygen in the atmosphere. Asteroids were constantly colliding with the material left over from the formation of the solar system. These collisions, combined with heat from radioactive disintegration, residual heat, and heat from contraction pressure, made the Earth It is completely molten at this stage.Heavier elements sink to the center, while lighter elements rise to the surface, thus creating the different layers of the earth.Scientists believe that the interior of the earth can be roughly divided into three constituent substances and properties Different concentric layers, the outermost layer is called the crust, the central part is called the earth’s core, and the middle layer is called the mantle. If the internal structure of the earth is a metaphor, it is like an egg, and the earth’s core is The mantle is equivalent to the egg yolk, the mantle is equivalent to the egg white, and the earth's crust is equivalent to the eggshell."

After listening to the explanation, the blue cat asked, "Then why is the earth the only one with life in the solar system?"

There is still the next level, the three naughty people hang their heads and defend the next level, and find that they can't beat the blue cat and the three of them. Speaking of which, the three mice are naughty and have fighting power, and Huang Chao and his group, everyone has good fighting power, and the blue cat is called "Super Power", which is not just for fun.

At the next level, Feifei was stimulated by his big cat and big dog, and stopped hiding. She took out a single cannon barrel from behind, aimed at it with the naked eye, and fired directly. His inclination was so perfect that the shell fell into the most suitable position location, blowing up the castle into ruins. Looking at her masterpiece, Feifei smiled with satisfaction.

"Go get the answer." Huang Chao said, and he and the blue cat quickly found a golden treasure box, and after opening it was a computer playing teaching videos.

"The earth ranks third among the nine planets in the solar system. It is 150 million kilometers away from the sun. This distance enables the earth to obtain enough energy, especially the temperature suitable for sustaining life. Compared with other planets, the earth has Appropriate mass and volume attract the life-supporting atmosphere. During the formation of the Earth, its inner layers were constantly moving, causing crustal movements such as volcanoes and earthquakes..."

"The earth's magnetic field also resists the solar wind and cosmic rays that can kill living things. The earth was formed at just the right time. After its surface cooled, the active activities of the earth's core prompted a large amount of carbon dioxide and water vapor to be discharged into the atmosphere, which is good for the heat preservation of the earth's surface. The formation of water is crucial. Volcanic activity also emits a large amount of methane, which is the basis for the formation of early organisms. Early lower organisms rely on the substances emitted by geological activities to produce oxygen for later organisms to survive, and finally after billions of years of vicissitudes The transformation that formed our home today."
