We are in the south, and it often rains during this time, so the weather is not too hot, but the weather in the north now, for example, the weather in Henan, is as high as 36 degrees, which is simply too scary.

Yongcheng, Henan, on May 18, when the local weather forecast reached 36 degrees, the road surface here was blown up by the high temperature weather, and the ground exposed by Uncle Sun was exploded. It turned out that the Yongcheng Meteorological Observatory issued an orange warning signal for high temperature at 10:30 on May 18, and it is expected that in the afternoon, the temperature in many places in our city may rise to more than 37 degrees.
Some local residents said that when it exploded, it felt like an earthquake, which was terrifying.
Looking at the ground, it was uneven, and the cement was bursting up.
There is a question, that is, although the weather is too hot, it will cause the cement on the road to burst up, but why do we here, we usually do not feel such a situation? Because we usually have the hottest weather here in the south, and we tried the ground temperature to exceed 40 degrees last year, so why don't we see such a situation here?
Some netizens said that this may be the sun again?
In fact, the explosion of the cement road is a relatively normal phenomenon, cold shrinkage and thermal expansion, it is also possible that when they make the ground cement, they did not cut the gap when they made it, or when they built the road surface, they did not reserve the gap, so it led to this road, under the situation that the relative temperature difference between cold and heat is too large, there will definitely be this cold shrinkage and thermal expansion. The relative temperature difference in our south is not too large, but if it is relatively compared to the north, the temperature difference in the north will be much larger.
