What is "ice volcanoes" and where do they occur?
Source:
Probably each of us had a chance to see the amazing natural phenomena like heavy rains and hurricanes. But under certain climatic conditions nature has to show us even more amazing spectacle like in deciduous forests and lakes formed in the ice . But did you know that at a certain temperature in lakes may be formed "ice volcanoes" from the crater from time to time bursts of ice water? Previously this rare natural phenomenon repeatedly observed in the lakes of Canada, but recently scientists were lucky to observe the activity of volcanoes on the territory of the U.S. state of Michigan. But how they are formed and what can be dangerous?
On education "ice volcanoes" in Michigan, the national weather service of the United States. It is important to note that they are completely different from ordinary volcanoes, which spew lava and can . In contrast, they are relatively innocuous, are formed only under certain weather conditions and usually disappear pretty fast. According to meteorologist Tom Niziol, this is a pretty rare sight and they are very lucky that they were able to remove formed ice volcanoes on camera.
the Most unusual volcanoes in the world
Since the "ice volcanoes" rarely appear on the surface of the lakes, scientists have long found their causes. They are formed when the level located under the ice water begins to change dramatically due to severe unrest. Under the influence of high pressure cold water comes out of cracks in the ice and quickly freezes, causing the surface formed a small hill. At their peaks, remain openings through which water continues to escape, because of what the hills look like erupting volcanoes.
Sometimes water pours out of the openings of unusual volcanoes seem to be boiling. This happens when the temperature sharply decreases and the water begins to quickly evaporate and form a vapor. In most cases, from the volcanoes poured dirty water, not clean as one would assume initially.
Ice volcanoes in Michigan
By Themselves, the "ice volcanoes" are not responsible for people no danger. However, it may happen that children or adults will want to climb on their top, which absolutely can not do. The fact that these slides are hollow inside and under the weight of the body, they can simply break down and people can drop in cold water. Out of the water, the more filled with shards of ice, can be extremely difficult. So if no one is around, any brave man could easily drown.
The entire history of observations, scientists have been able to find the "ice volcanoes" up to a height of ten meters. But they are formed only in cases when necessary for their education the weather conditions are held for a very long time. And so, the height of the ice formations usually does not exceed 1-2 meters, because they melt quickly in the warming air.
Generally, unusual phenomena occur not only due to certain weather conditions. Recently, residents of the Indian city of Chennai is literally bathed in the frothy water of the local beach, but they did not even know that it's poisonous. About the cause of toxicity formed in the foam beach you can read in our .
Ice volcanoes can have very different forms.
