The fact that a volcano and how it appears, the inhabitants of our planet began to think back to ancient times.
For example, the ancient Romans called the volcano mountain, which is home to the fire god Vulcan.When he began the dangerous work of the mountain was smoke and fire erupted.Kamchadals believed that the spirits of fire-spitting volcanoes mountains are visiting souls of the dead, and the smoke is visible when they start to heat their yurts.Indians of North America, who lived at the foot of Mount Mazama, believed that his eruption occurred during the struggle between good and evil god of snow god of fire.
But how to explain that such a volcano experts.Volcano - is naturally formed due to the displacement of tectonic plates hole in the earth's crust, from which it is ejected under tremendous pressure, often accompanied by an explosion, molten lava, and along with it - steam, gases and ashes.
On the African continent is one of the unusual volcanic planet - Oldoinyo-Lengai.Its crater with a diameter of 400 m, is filled with a white substance, but it does not snow, and soda ash.Surprisingly, it has risen from the depths of the earth, because this volcano - the only one whose lava instead of the usual silicon contains minerals calcium, potassium and sodium.It is called the cold, because the temperature of the lava twice lower than usual.During the day it looks black, and only with the coming of darkness, it becomes clear that in fact it is a dark crimson color.Then, gradually cooled, the lava becomes white.Soda water flow is carried away in a beautiful lake, nestled like a pink blanket.This is another amazing moment because pink blanket - a lot of flamingos, which are attracted to spirulina, one of the few organisms that live in the "soda" water.
Vulcan Hephaestus located on the hill Rotten Taman Peninsula is unique in that it is a volcano, spewing fountains of mud.This mud called peloid, saturated with boron, bromine, iodine, selenium, and used as therapeutic agents in medicine.Right in the crater of the volcano arrange a mud bath, the temperature ranges from +12 to +20 degrees Celsius.
Volcanoes in Iceland over 60 million years, are an unceasing struggle with glaciers.Over the last two centuries of the 20 volcanoes almost half at least once showed their activity.And one of the largest eruptions on the island lasted for almost two years during the 1821-1823 biennium.- It was the Eyjafjallajökull.By the way, in 2010 by its action it practically melted in a few days, a huge glacier of the same name at the same time provoked the activity of another volcano - Katla.According to experts, volcanoes and earthquakes, their constant companions, will be felt over the next 60 years.
What's a volcano in space?In 2005, Enceladus (moon of Saturn) Cassini Space Station registered active volcanoes.On hundreds of kilometers we are not erupted lava and fountains of water, which immediately turned into a mist of ice crystals.A little earlier, in 1989, it became aware of the volcanic activity on Triton (moon of Neptune).There, on one of the coldest bodies in the solar system (- 240 degrees Celsius), were found nitrogen geysers, solar heat activated.
So what is a volcano - fire-breathing mountain mud geyser fountain or gas?
