On the earth we live in, there are always some very special natural phenomena, and these natural phenomena are constantly attracting the exploration of scientists. It is also with the in-depth exploration of natural scientists that some seemingly wonderful natural phenomena have been revealed.
There used to be some people who were particularly adventurous, and they gathered in the snowy mountains to prepare for climbing. Then after these people reached the top of the mountain, they could not hide their joy, and some of them shouted loudly, trying to express their inner surprise in this way.
However, as the climber's voice landed, a very terrifying thing happened. The snow mountain they were in actually collapsed, and white snow kept rolling in. So what causes this phenomenon to happen? Why does shouting at the top of a snowy mountain cause it to collapse?
Here are some physical reasons for this phenomenon:
1. There is snow on the snow-capped mountains, and the snow is relatively loose. The temperature on the high mountains is generally lower, and there will be "snow lines" above a certain altitude. The so-called snow line means that the tops above this line are covered with snow. Since the top of the mountain is inaccessible, the snow is uncompressed and fluffy.
2. Due to the special environment of the mountain, the sound cannot be absorbed. The human voice is reflected back and forth in the mountains, causing vibrations to the snow, while the snow on the most vulnerable peaks receives sound waves and vibrates, under the action of gravitational acceleration, it affects the snow below, thereby causing an avalanche.
3. The snow-capped mountains are rarely affected by the outside world due to the inaccessibility of people, and the long-term snow accumulation is in a very delicate balance. When people shouted loudly, the resulting sound waves caused tiny vibrations in the snow on the mountain. At this time, a small amount of snow will roll down, and the falling snow will generate a larger vibration, and then the impact will become larger and larger, eventually causing an avalanche.
This phenomenon actually refers to the tendency of a physical system to absorb more energy from its surroundings at its natural vibrational frequency. Under the influence of this energy trend, a particularly powerful force is generated, and this force is enough to cause some large objects such as various buildings to collapse.
Instructions for escaping in an avalanche:
To escape from an avalanche, no matter what kind of situation occurs, you must immediately stay away from the route of the avalanche, and you must judge the situation at that time. When this happens, people instinctively run straight down the mountain. But the ice and snow also fell down the mountain at this time. And the speed sometimes reaches 200 kilometers per hour, running down is dangerous, and you may be buried in ice and snow. It is safer to run to both sides at this time.
At the same time, get rid of all bulky items such as backpacks, skis, ski poles, etc. With these items, it will be more difficult to move around if you unfortunately get stuck in the snow. However, if you are on the edge of an avalanche route, you can use these tools to sprint out of danger. If you are buried in an avalanche and cannot get rid of it, remember to keep your mouth closed to avoid suffocation by ice and snow pouring into your throat and lungs.
