Su Yun laughed dryly and said, "Earthquake... How can I explain this?!" I can't tell them about the geological problems that the geography teacher said in class?!

Forget it, she wasn't that crazy, and then just said: "An earthquake is when the earth is shaking, and then there are some cracks, and this is an earthquake." ”

Zi Mo looked at Su Yun, for a long time, for a long time, and he was puzzled more and more, why did Yun'er know so many things he didn't know?!, but he still didn't ask, just nodded, and ordered to Fengying Fengxing: "You two, go to Tongshan, evacuate the people at the foot of Tongshan as soon as possible, and then go to find a few temporary shelters for the people." ”

Wind Shadow took the command and left in a hurry.

Meng Jinxi touched Su Yun's arm and asked, "Yun'er, what is the earthquake?!"

Su Yun said, "Earthquakes are actually very easy to say, but if you don't know the composition of the earth's crust, it's troublesome to talk about. ”

"I think, you should know that the land is made up of a lot of soil, right?! In fact, there is groundwater at the bottom of these, and the groundwater supports the ground, and the ground drifts around with the groundwater, and then sometimes collides, sometimes separates, and gradually forms mountains, rivers, lakes, and oceans.

Some of them are lower and slowly sink to form basins, but even then, these crusts will flutter, and whenever they flutter and collide together, they will cause the layers of rock buried deep underground to break.

In addition, due to the rupture and dislocation of rocks deep underground, the energy accumulated over a long period of time is released sharply, and it spreads in all directions in the form of seismic waves, and the shaking of the house caused by the ground is called a tectonic earthquake. ”

After speaking, Meng Jinxi blinked his eyes a little confusedly, what is that?!, and then asked Suyun: "Yun'er, I understand everything else, but what is this seismic wave?"

Su Yun raised her head and held her forehead, she shouldn't have said this! Why do you say that she is a scumbag student studying with the top students and telling this?!

Of course, Meng Jinxi would ask questions about what she wanted to know, and then tightly tugged on the sleeves of Su Yun's clothes, not letting go of anything, and then looked at Su Yun with her blind but still crystal clear eyes.

Blink, wink.

If you want to ask who is the last to compromise?!, of course, it must be Suyun!

Su Yun looked at Meng Jinxi's big eyes, blinked his teeth, and finally couldn't help it, and then said: "Okay, okay, okay, even if I'm afraid of you, can't I? ”

Meng Jinxi finished, the stunned on his face was obvious, he looked at Su Yun and said, "How many hundred miles around?!Wouldn't this be a bit exaggerated?!"

Su Yun rubbed Meng Jinxi's small~ face, and then said: "Jinxi, you underestimate the power of the earthquake, there used to be a place in my hometown, which is the same as Tongshan, that place is called Tangshan, and in 1976, there was an earthquake.

The house collapsed to the ground in an instant, killing and injuring countless people.

Corpses littered the field.

People were powerless against nature and had to watch their homes buried in an earthquake.

Loved ones, children, and even oneself may not be able to save their lives. ”

When Meng Jinxi heard this, she always felt that it was not a taste. Then I heard Su Yun say: "My grandfather died there to save a child during the Tangshan earthquake..."
