Yu Jing immediately replied: "When the celestial body lands, it will cause severe friction with the atmosphere, and then produce extremely high temperatures, so when it approaches the ground, it will incinerate everything around it. It turns out that there is a thick layer of mountains.
The vegetation will also be burned to ashes on the spot."
She then raised her telescope and looked at the distant mountains and continued to analyze: "When the celestial body hits this mountain, it will produce a very violent explosion. The equivalent of the explosion must be at least hundreds of thousands of tons, and a violent explosion will produce even more violent explosions.
The high temperature and huge shock waves will definitely become scorched earth around you. Look at the mountains in the distance, there are black spots everywhere in the gray rocks, which should be traces left after the explosion."
At this time, Xiaoya said in surprise: "The explosion equivalent of hundreds of thousands? This is many times greater than the power of the explosion in Hiroshima in the late World War II!"
Yu Jing replied with a serious expression: "Yes, the power of the explosion at that time was only equivalent to 20,000 tons, but at that time the explosion center was already as high as 6,000 degrees, which directly caused 60,000 deaths on the spot that day."
Wu Xueying heard Yu Jing's story, and she shouted in surprise: "It only costs 20,000 tons to cause such great damage! Then this unknown celestial body hits here like dozens of them. How much damage will it cause?
?”
Yu Jing said: "Yes, this kind of celestial body crashing into the earth is indeed a devastating disaster to the living creatures on earth. Fortunately, this unknown celestial body landed on this deserted plateau, so it is for us humans and
No life damage.”
She followed: "A few years ago, a space rock with a diameter of 15 meters and a weight of 7,000 tons also hit our earth. The energy it released when it hits the earth is equivalent to an explosion of 500,000 tons, causing about 1,500 people to be injured.
Fortunately, it is sparsely populated and does not cause large-scale damage. If the space rock falls directly into a city, it can destroy the city on the spot, which is very powerful."
Xiaoya and the others listened to Yu Jing's introduction, and the others shouted in surprise: "Oh my god, this is too scary, it's simply destructive!" Xiaoya looked at the surrounding mountains with some fear and said.
: "Thanks to this unknown celestial body that fell into the city, otherwise I don't know how much damage it will cause!"
Yu Jing saw the fear of several people and said with a smile: "No. In astronomy, these stars flying straight to the earth in space are called meteorites, and those that fall on the earth are called meteorites, and those that fall on the earth are called meteorites, and they can
The probability of meteorites directly landing into the city is very small. According to astronomers' estimates, the earth receives about 50,000 tons of meteorites from space every day. Most of these meteorites are burned in the atmosphere during the landing process, with only some of them being smaller in size.
Only the big ones will fall on the earth.”
She raised her hand and pointed to the surrounding mountains and continued to say, "Our land area accounts for only 29% of the surface of the earth, and the rest are oceans. And this 29% of land is also perfect for
Humans live and activities. Relevant information shows that the areas where we live and activities occupy only about one-fifth of the earth's land area. In this way, the chances of meteorites falling over our heads are slim, so you don't have to worry."
When Wu Xueying heard this, she said with confidence: "Okay, okay, just don't hit our heads." Yu Jing smiled at her. She raised her telescope and looked at the mountain in front and continued, "Yingying, look,
Judging from the situation in the mountains ahead, this celestial body that fell on the earth is not very large. There is a huge crater in Country M., which is 170 meters deep and has a diameter of 1,240 meters."
Wu Xueying exclaimed: "Such a big meteorite?" Yu Jing turned her head and looked at her and said: "Is this big? There is also a large crater in the Antarctic with a diameter of 300 kilometers, and there is also a giant in the Pacific with a diameter of more than 1,000 kilometers.
Where is the crater."
Everyone around looked at Yu Jing in surprise, and Yu Jing followed: "Such a large meteorite fell on Earth, which caused huge changes in the earth's climate and organisms at that time, and this also directly led to the evolution of organisms on Earth."
She turned around and pointed to the green mountains behind her and continued, "Look at this green mountains. In the past, this place should have been a typical plateau terrain and vegetation, but now we see a beautiful scenery like the water town in the south of the Yangtze River. This is
The drastic changes caused by this unknown object landing here.”
Yu Jing said this and looked at the vibrant mountains behind her and sighed: "In the past, I have studied astrophysics specifically and have some understanding of the evolution of the universe and the earth. In most people's eyes, it is a catastrophic meteorite landing.
In fact, it has also brought about repeated evolution and evolution of environment and organisms to our ancient earth."
She paused at this point, then turned to the sad mountain area in front of her and continued: "This was indeed a disaster at that time, but when we observe from a perspective of thousands of years and billions of years later, this time,
We seem to have devastating impacts that may be opportunities to promote the evolution of this ancient planet. So, we have been saying that everything has its own two sides and must not easily draw conclusions. For those of us who are doing research,
Even more so."
Yu Jing's voice was slowly telling, Xiaoya and others looked at Yu Jing's beautiful and wise face with respect, and they all admired this female scientist like an elder sister in their hearts. Wu Xueying looked at Yu Jing admiringly
He said, "Sister Yu, how do you know so much?"
Yu Jing smiled faintly, and she hugged the little sister's shoulder and said with a smile: "What's the matter? Because this is my job. Just like this mission, I am a burden in the eyes of you special forces soldiers.
, because I can't compare with you special-trained special warriors."
Wu Xueying quickly replied, "You are not a burden, you are our guiding light. We will go wherever you point." Everyone around laughed. Yu Jing raised his hand and tapped Wu Xueying's helmet and smiled: "
Stinky girl, her mouth is as sweet as honey. Just don’t dislike me as a burden.”
At this time, Wan Lin smiled and said, "Mr. Yu, you are not a burden to this action. In such a special area with unknown circumstances, it would be difficult for us to move forward without your guidance."
Yu Jing smiled and looked at him and said, "Okay, you just need not treat me as a burden! I will come out with you this time, I am really afraid of causing trouble for you."
