This issue's topic: Storm
Keywords: meteorite moon
Added knowledge point: "Look across the entire Mexican forest and you'll find hundreds of flooded Mexican caves connected to each other forming a giant semicircle and here's a giant crater"
After watching: Although I knew that the dinosaurs were extinct because of the falling of meteorites, I only knew that it was a hypothesis. I didn’t expect that there are still craters!
Added knowledge point: "The meteorite's falling location is right in the sulfur mining area. After the sulfur ore gasification, hundreds of thousands of tons of harmful gas smoke and dust are generated all year round.
The earth fell into a low temperature due to the lack of sunlight all the year round, and the dinosaurs went extinct immediately"
After watching: It is the so-called butterfly effect. A meteorite completely changed the fate of dinosaurs and the fate of the earth. I really want to say that it is the extinction meteor of dinosaurs, but it is the cornerstone of human beings!
Reminds me of what the ancients said, if you don't break it, don't break it, then stand up!
carbonaceous chondrites
4.6 billion years ago, where the earth was located, there was a huge cloud-like star surrounding the sun that was just born.
Additional knowledge points: "The origin of cosmic storms is that a group of particles gather together under the action of static electricity, although the process is very slow, these clumps will eventually condense into a solid, although only the size of a grain of sand, but can already use its own gravity to continue. adsorbed other particles
These particles gather into rocks, they either destroy each other or multiply and condense, and the collision intensity increases sharply.
Under the dual action of high temperature and high pressure, these stones began to gradually change to build our planet."
After watching: I have increased my knowledge again. I didn't expect the earth to be so composed. The particle as large as a grain of sand is like a powerful magnet!
Appears to be a stable adhesive at high temperatures and pressures.
High temperature and high pressure and those particles have jointly completed the "first draft" called Earth!
Reminiscent of a sentence, any greatness starts from ordinary, grows step by step, and finally can have brilliant achievements!
Added knowledge point: "These rubble provide all the necessary elements except water for a life-bearing planet in the process of colliding and breaking up"
After watching: The earth originally had no water!
Growing knowledge: "The water that initially condensed into hail on Earth came from space is spectacular. It lasted for 100 million years and was covered in ice. Comets and asteroids collided with Earth to provide us with vital water resources.
The water on the surface of the earth gathers into a vast ocean and is concentrated at just the right position from the sun, which is the habitable zone.
The vast expanse of the solar system, the earth will move to other locations at any time, causing the water to condense into ice or evaporate.”
After Viewing: New Knowledge!
Increased knowledge point: "The mainstream view of the earth and the moon is the same root and the same origin. There are other stars in the habitable zone, that is, a planet called Theia.
Its orbit intersects with the Earth's orbit, resulting in a collision
After the two planets collide, they will be swallowed by lava, and some debris will be thrown into the vast space. After the debris cools down, it will condense into a new pair of partners in the universe. This is the moon and the earth."
After watching: I used to wonder why there is a saying that the moon is the "sister" planet of the earth?
Years of doubts have been solved, it turns out that the moon was split from the earth!
Increased knowledge: "The moon split from the earth. The moon is so close to us that it pulls and pushes on the oceans of the earth. The tides on earth come from this.
The violent impact that spawned the moon made the earth spin so fast that there were only five hours a day at that time
It is the tidal pull of the moon that slows the earth's rotation and gradually becomes a 24-hour day
It also brought us a different kind of gift, the four seasons are distinct"
After watching: I only knew that the sun is very important to us human beings before, but I did not expect that the moon in the sky is not only a "sentimental object" that provides human beings with various romantic feelings and inspires poetry.
I didn't expect the moon to have such an important impact on our lives!
Added little knowledge: "The Earth's axis is deviated due to this impact, making our Earth tilt 23.5 degrees from the Sun
If the earth hadn't tilted, half of the world would be covered with snow and ice all year round. If you live near the equator, you'd be lucky, but if you live in northern China, it means winter all year round.
Because of this tilt of the earth, all kinds of creatures are almost all over the world, and life on our planet is in sync with the seasons.”
After watching: The key percentage has appeared again, the earth and the sun are tilted by 23.5 degrees!
Reminds me of an idiom that is a thousand miles away!
Increased knowledge: "The inclination of the earth and the sun means that the four seasons flow alternately between cold and heat, allowing us to enjoy the spring of flowers, the color of the sea, the summer of sunset, the autumn of snow and the winter of winter"
After watching: Sometimes the beauty of the beautiful scenery is probably the change of angle!
This gave me a little inspiration. There are some troublesome things in life, and sometimes thinking about it from a different angle may make people feel completely different, just like a flower on the bank of a willow!
