The 380,000-kilometer-long moon is the earth’s only natural satellite. It has been accompanying the earth from the moment of its birth. According to current research by astronomers, it is speculated that our moon was born regarding 4.5 billion years ago and was impacted by a celestial body. Forming. About 4.5 billion years ago, the Earth had just accreted from the remaining material in the solar system. Coincidentally, a celestial body also formed near the same orbit of the Earth. This celestial body was regarding the same size as Mars. It was named Infinity. Oia. Since Theia is not far from the primitive Earth, this means that they will be getting closer and closer under the force of gravity. Finally, one day it will collide with the primitive Earth. The moment of collision can be said to be very violent. Oia was almost completely shattered by the impact. The violent impact caused a large number of fragments to fly into space. Then these fragments gathered near the Earth’s orbit due to gravity, forming the moon. Nowadays, with the advancement of science, we have been able to set foot on this land through rockets. In the 1960s, humans landed on the lunar surface six times. In our continuous exploration, we have learned more and more regarding the moon and discovered that it Played a critical role in the earth. So let’s assume today, what would happen to the earth if the moon disappeared? As we all know, the water on the earth will rise and fall periodically, and this phenomenon is caused by the gravitational influence of the sun and the moon. Although the sun is much more massive than the moon, it is so far away that the moon’s tidal force is regarding 2.17 times that of the sun. If the moon disappears, this will lead to a great reduction in tidal action. The most direct impact will be the backflow of seawater and atmosphere on the earth, which will trigger huge tsunamis and super storms. Coastal cities around the world will face terrible tsunami attacks. , this kind of tsunami is unprecedented. In addition to the influence of tides, the earth’s rotation axis is actually related to the moon. We know that the earth has an inclination angle, regarding 23.5 degrees, and this inclination angle was caused by the impact of the planet Theia at that time. If the moon disappears, the earth’s axis of rotation will become unstable and it will swing back and forth greatly, and the earth will no longer have four distinct seasons. In other words, due to unstable rotation, glaciers may appear in the hot African regions, while deserts or jungles may appear in the cold Antarctic regions. This means that creatures living on the earth will continue to be affected by extreme climate changes. , some organisms may be on the road to extinction. Not only that, if the moon disappears, the possibility of being hit by meteorites on the earth will also be greatly increased. The moon has always been known as the patron saint of the earth. It has resisted the impact of many asteroids for the earth. Once the moon disappears, Then the original asteroids will also hit the earth’s surface. Therefore, the moon is very important to the creatures on the earth. Without the existence of the moon, there may not be life on the earth, and there would be no human beings. Therefore, in a sense, we would also like to thank the moon for giving Our lives! Expand Reading How empty is the universe? After reading it, it may be beyond ordinary people’s cognition!
