The disaster may be different, but one of the most dangerous is rightly recognized as a volcanic eruption. Every day on the planet takes place up to ten of these releases, many of which people don't even notice.

What is a volcano?

what comes out of the volcano during the eruption

The Volcano is called geological formation, located on the surface of the crust. The locations of the craters comes out of magma to form the lava, which is followed by the gases and fragments of rock.

The name of the stone giant received from the Roman God of fire, bearing the majestic name of the Volcano.

Classification

These mountains can be classified according to several characteristics. So, for example, in the form of these formations are divided into the following vide:

  1. Setevye.
  2. Stratovulkan.
  3. Shlamovye.
  4. Consobrina.
  5. Kopalnie.

In Addition, volcanoes can be identified depending on their location:

  1. Ground.
  2. Underwater.
  3. Subglacial.

Besides, among inhabitants, there is another simple classification, which depends on the degree of activity of the volcanoes:

  1. Current. This education is characterized by the fact that it has erupted relatively recently.
  2. A dormant volcano. Under this definition, means a mountain, which is currently inactive, but in the future eruption may occur.
  3. The Extinct volcano – tectonic education, no longer having the opportunity to gush forth.

Why do volcanoes erupt?

Before we deal with those products that come out of the volcano during the eruption, it is necessary to know what constitutes this formidable phenomenon, and what are its causes.

The eruption means the release of surface lava flows, which is accompanied by emission of gases and ash. Volcanoes erupt because of the large number of substances accumulated in the magma.

Magma is constantly under very high pressure, so gases always remain in the dissolved liquid. Molten rock, which the pressure of volatile substances gradually pushes to the surface through cracks and into the hard layers of the mantle. Here, the magma is rapidly coming out.

It would Seem, must be no more questions about what appears in the volcanic eruption, because magma turns to lava and poured onto the surface. But in fact, during the eruption, in addition to these components, to show himself to the world can many different substances.

Lava

what comes out during the eruption of the volcano

Lava – is the most famous product released during volcanic activity. It is often quoted by people answering the question: ‘What comes out of the volcano during the eruption?”. The photo of this red substance can be seen in the article.

The Lava masses represent a compound of silicon, aluminum and other metals. There is also an interesting fact associated with it: we know that this is the only earthly product, where you can find all the elements located in the periodic table.

Lava – red-hot magma, which flows from the crater of the volcano and sent down its slopes. During ascent, the composition of the underground ladies changing due to atmospheric factors. In addition, a large number of gases, which along with the magma rise to the surface, making it bubble.

The Average temperature of lava is 1000 degrees, so it is easy to destroy all obstacles standing in her way.

Wreckage

No less interesting to see what comes out during the eruption of a volcano besides lava. In the middle of the earth's surface thrown a lot of debris that scientists call "TEFRA".

Of the total mass allocate the largest fragments, nicknamed the “volcanic bombs”. These fragments are liquid products during a release freeze in the air. The size of these stones may vary: the smallest of them like peas, and the biggest ones exceed the size of a walnut.

Ash

Also, answering the question ‘What comes out of a volcano?”, we should not forget about ash. It often leads to disastrous consequences, as distinguished even with a slight eruption, which can't harm people.

Fine particles of ash float through the air with great speed – up to 100 kilometers per hour. Of course, a significant amount of this substance can get a man in the throat during breathing, so the eruption should cover his face with a handkerchief or a special respirator. Feature of fly ash is that it is able to cross great distances, even bypassing the water and hills. These fine particles are so hot that permanently glow in the dark.

Do Not forget about what comes out of the volcano during the eruption, among other things, a large amount of gas. The composition of this volatile mixture includes hydrogen, sulfur and carbon. In a minorquantities contains boron, bromine acid, mercury, metals.

All the gases that stand out from the crater of the volcano during the eruption, are white. But if the gases mixed with the tephra, the clubs acquire black shade. It is often as black smoke coming from a volcanic crater, the people determine what will happen soon emissions need to evacuate.

You Also need to know what comes out of the volcano during the eruption, in addition to the above substances. It is a strong smell of hydrogen sulfide. So, for example, on some Islands of volcanic spirit extends to hundreds of kilometers.

Interesting fact: a small amount of gas continues to stand out from the crater of the volcano within a few years of eruption. In addition, these emissions are very toxic and once in the water with rain, they poison it and make unfit for drinking.
