Duoduo and Lisa looked in the direction I was pointing, and were stunned by the sight before them. Seeing such a strange phenomenon was something they had never seen before. Therefore, they couldn't help but sigh: "What a beautiful beauty in the world!" Just seeing this scene, our adventure trip was very worthwhile! ”

Hearing the exclamation of the two, the rest of the people also turned their heads to look. Equally, I was stunned by the beautiful scenery in front of me. Lisa couldn't help but exclaim, "Wow, what a beauty! One heaven and one hell! ”

Duoduo also cheered with her, looking beautiful. I saw that the smile on Duoduo's face was so beautiful at this time, she hadn't been so happy in a long time. It was at the moment when I saw Duoduo's smile that I truly realized that this trip was without hesitation and without complaints.

While everyone was busy enjoying the beautiful scenery, the big man seemed to have no leisure to enjoy the beautiful scenery, and just blindly urged us to hurry up.

Lisa and Duoduo were seeing the excitement, and when they saw that the big man was urging so urgently, they said with some displeasure: "What a wood that doesn't understand the amorous feelings!" ”

I saw that the big man, who had always been calm as water, looked a little cramped, so I asked him, "Big brother, what do you see?" Why are you so nervous? ”

The big man replied with some nervousness: "Looking at the climatic conditions and the surrounding geographical structure, coupled with the accumulation of snow over the years, I judge that there is a high probability of a large-scale collapse!" So, everyone should be careful not to make too much noise. ”

"Are you saying there's a good chance of a collapse here and a massive avalanche?" When Qian Cheng heard the big man say this, he speculated calmly with an expression.

"Avalanche?" When the old ghost heard the big man say this, he asked with some surprise, "Aren't we very dangerous?" What to do? Is there a way to prevent or help yourself? ”

At this moment, there was a sudden explosion of thunder in the sky, and almost the entire valley shook with a lot of movement!

Hear such movements. Several of us were a little surprised. More worry, to be exact. The big man hurriedly picked up the binoculars on his chest and looked around, as if to carefully examine what might be happening around him.

When we see the big man like this, we also keep silent in amusement. Almost at the same moment, several people picked up their few binoculars at the same time and looked at them.

I'm really afraid of something! As soon as we raised the telescope, we heard a muffled "click, click". As soon as you hear the movement, you will know. That's the sound of ice breaking! However, judging by the movement, it seems that it is not the sound around us, but it seems to be far away from us.

"Over there! It's over there! The big man observed for a long time, and pointed his hand to a mountain next to us.

We looked in the direction he was pointing, and sure enough, we saw a mist of snow rising there. The "click" sound didn't stop, and it made a louder sound one after another. Listening to the movement, we immediately checked with our binoculars again.

I saw the ice and snow on the slope of the mountainside. It poured down like a tidal wave from top to bottom. As the snow and ice slid down, a thick cloud of snow mist rose above.

Seeing that it wasn't on our side, the big man breathed a sigh of relief and said, "Don't worry for the time being, it's not our side that has an avalanche." However, I still recommend a place where everyone walks together and has something to rely on. In case, if something bad happens, we can save ourselves! ”

In fact. We all understood what the big man meant: let's go where there is a block, in case there is an avalanche. We can also find a place to hide.

In this snowy region, the big man is the expert, the authority on us, and he is what he says. The point is, we all feel very reasonable, and we all trust him very much. Thereupon. Our group changed course slightly, trying to go where there was a block.

Seeing that there was no threat, the big one said to everyone again: "Just in case, I think, I'll give you some knowledge about avalanche." In case you run into it in the future. At least I can learn to help myself a little! ”

Hearing the big one say this, the old ghost said a little unhappily: "Crow's mouth, who wants to meet this?" If you don't say it, we won't, and it's not like we're in an avalanche. ”

As soon as I heard that the big man was going to say something about what was going to happen in the future, I suddenly became extremely curious, so I hurriedly stopped the old ghost and said to the big man, "Big brother, you say, you don't pay attention to him. In this snowy country, it's hard to say anything, if you don't let it go, we should also have a long knowledge. ”

Seeing that I was so enthusiastic, the big man nodded and said, "Anyway, there is nothing to do while walking, so I'll talk about it:

An avalanche is usually a state of 'dangerous' equilibrium in which the snow is covered, which is commonly referred to as a 'crumbling' feeling. If there is a slight external force, the balance will be lost. This causes the snow to slide, which in turn causes more snow movement and causes a large amount of snow to pour down instantly.

Usually a large amount of snow falls suddenly from a high place. Avalanches can occur in all snow-covered mountains, and the collapse speed can reach 20-30 m/s, which is characterized by suddenness, fast movement and great destructive power.

Avalanches are also a common natural disaster in the mountains where snow is covered all year round, and many people die from avalanches every year. It often causes houses to collapse and casualties.

It destroys forests and buries houses; Faults in transportation lines, communication facilities and vehicles, and even the blocking of rivers can cause natural disasters such as landslides, landslides, and mudslides. As a result, avalanches have been listed as one of the most severe natural disasters in snow-covered mountainous areas.

An avalanche is often the result of a combination of factors:

One reason for this is the slow formation of deep "hoarfrost" beneath the snowdrifts, which is a hexagonal cup-shaped crystal of ice that resembles the ice ballast that one usually sees.

The formation of this hoarfrost is caused by the evaporation of snow particles, which are much looser than the snow in the upper part. A zone of weakness is formed between the ground or lower snow and the upper layer of snow. When the upper snow begins to slide down the slope, this belt acts as a lubricator. Not only does it speed up the snow slide, but it also moves the snow around it that is not slipping.

As a result, large areas of snow slide, causing avalanches. ”

Hearing this, the old ghost hurriedly raised his hand and asked, "Let me interject, will skiing cause an avalanche?" If that's the case, isn't skiing dangerous? ”

When the big man heard the old ghost's question, he smiled slightly, and said, "That's not true! Skiing is generally a relatively fixed and safe enough venue. (To be continued......)
