The 380,000-kilometer-long moon is the earth’s only natural satellite. It has been accompanying the earth from the moment it was born. According to current research by astronomers, our moon was born about 4.5 billion years ago and was formed by acelestial bodyformed by impact.
About 4.5 billion years ago, the Earth had justsolar systemIt was formed by accretion from the remaining matter. Coincidentally, a celestial body was also formed near the same orbit of the Earth. The size of this celestial body is about the same as that of the Earth.MarsRather, it was named Theia.
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 about 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 about 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 rotation axis of the earth is actually related to the moon. We know that the earth has aTilt angle, is about 23.5 degrees, and this tilt 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, it may occur in the hot African region.glacierand the cold Antarctic region may turn into a desert or jungle, which means that the creatures living on the earth will continue to be affected by extreme climate changes, and some creatures may be on the road to extinction.
Not only that, if the moon disappears, what will happen to the earth?meteoriteThe possibility of impact will also be greatly increased. The moon has always been known as the patron saint of the earth. It has protected the earth from the impact of many asteroids. Once the moon disappears, all the original asteroids will also impact 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!
