Volcano is a place, crevice, or face present on the surface of the earth, from which melt rock, warm lava, gas, ash etc. come out of the earth. The thing that comes out of the volcano is known as magma which turns into lava after coming out. The lava flown out in the air quickly cools down into small solid pieces called 'cinders'. Today there are thousands of active volcanoes on Earth which are the most fatal for human life. As many volcanoes exist on Earth, most of them are ten thousand to one million years old. Along with the time, their height also increases.
What are volcanoes -
Speaking in simple language, the volcano is a mountain with a melt lava. The stones beneath the earth melted due to the energy of geothermal energy. When the pressure increases up from under the ground, the mountain breaks up and called volcano.
Molten stones and gases below the volcano are called magma. When it comes out after the volcanic eruption it is called lava. By the eruption of the volcano, the gas and the stone rise up. The lava flows through its burst, as well as hot ashes also flowing with the wind. Landslides and floods also occur due to the turmoil underground.
How do volcanoes become and how are explosions?
A volcano is said to be caused by a center or a hole or a crack. Central erosion volcanoes are often accompanied by fierce and intense speed, because in lashing, lava often moves out and spreads to the ground. The exclamation lava and other substances reach the sky at higher altitudes, and in the sky are often cloudy and the fragmented substances quickly fall. These volcanoes are more fierce and devastating. There are many types of central volcano volcano eruptions, intervals and according to nature, which are divided into several sections on the basis of specific volcanoes. Among these are the major types: Hawaii, Stromboli, Volcano, Palin, and Vesuvius equivalent volcanoes.
The explosion of a volcano depends on the emission speed of the magma, and the emission speed of the gas contained in the magma. Magma has very high amounts of water and carbon dioxide. By seeing magma emerging from an active volcano, it is found that the action of its gas emission resembles the action of gas extraction from a carbonated beverage.
There are also many types of toxic gases with magma in the volcano. These gases are quite fatal for people living nearby. Magma emanating from these mountains is like a flowing fire. It completely eliminates everything in front of you.
Magma comes up very quickly from the ground layer and grows by 1000 times its original size. Volcanoes can be of many sizes. Some volcanoes are shaped like a right angle, some volcanoes are filled with very deep water. Based on the different shapes of the volcano, it is known by three different names.
Before the volcano eruption signal
Before the volcano erupts, some changes are generally seen. Among them, the level of water present near that place suddenly increases. Before the volcano bursts, there are some light shocks of earthquakes. Apart from all these things, the volcano gives itself an indication of what the catastrophe is all about. If the volcano is a bursting mountain, the leakage of gases starts from that mountain. This leak of gases comes from its mouth (mouth) or 'crater'. Apart from this, there is a leak of these gases from the cracks created in many places in the mountain. It is a sign that the time has come for the fire to blow. These gases contain major gases such as sulfur-dioxide, carbon-dioxide, hydrogen chloride etc. Of these, hydrogen-chloride and carbon-dioxide are extremely dangerous.
Active and passive volcano -
Any volcano is considered to be alive until it comes out of lava, gas etc. If the lava does not come out of the volcano then it is called a dormant volcano. Passive volcano may be active in the future. If a volcano is inactive for 10,000 years then it is called a dead volcano.
Types of Volcanoes
According to an estimate, so far there are around 1500 live volcanoes in the world. Himalaya is a dead volcano, so there is no possibility of any danger from it. But on the other side, there are many other living volcanoes including 'Mount Etna', because they keep rising from time to time lava and gas. Volcanoes are mainly of three types. The description of these three types of volcano is given below.
1). Shield Volcano
If the magma is very hot and is coming out of the ground at very high speed then the explosion is normal. The magma coming out of it is very high. Due to the lava flowing very smoothly, it is accumulated in a certain way on the face of the volcano, and its sloping decreases when away from the source of the volcano. The magma of this type of volcano is between about 800 to 1200 degree centigrade.
2). Composite Volcano
There is a special kind of explosion in this type of volcano. When the temperature of the magma gets slightly reduced, it starts to freeze and gas is spreading out and it is difficult to get out. As a result, the magma coming from below the ground expands with too much force and explodes. In such volcanoes, lava flows in a certain way, which is called a wave. The lava of this volcanic lava is between 800 to 1000 degree centigrade.
3). Caldera Volcano
Such a volcanic eruption explains that most of the lava accumulates on the face of the volcano, and the size of the volcano becomes like a basin. Lava coming from this volcano is very sticky. Its lava is relatively cooler than the remaining volcano lava. The temperature of its magma is between 650 and 800 degrees centigrade.
What kind of volcano are there?
There are three types of volcanoes in place. The first type of volcano is like a hollow hill that causes lava. The second-class volcanoes are high mountains, which contain several tunnels, to which the lava emerges. The third kind of volcano found in Hawaii. These are like flat mountains. A fourth type of volcano is called lava dome. It is a lava accumulated in a place which cools down over time but sometimes such domes burst.
Existence of volcano -
More than 80 percent of the Earth's surface is the result of volcanic eruptions. Lava coming out of it would have been frozen millions of years ago and it would have made the ground surface. Sea level and many mountains are also a volcano lava. The atmospheres formed from the volcanic eruptions.
Volcanoes are not only present on Earth, but they also exist in the oceans. There are about ten thousand volcanoes in the sea. Even today many volcanoes are left out of the eyes of scientists. Destructive tsunami waves are also formed by volcanic eruptions within the ocean. The largest volcano is in Hawaii. Its name is 'Mona Lo'. It is about 13,000 feet high. If it is measured by the depth of the sea, then it is about 29,000 feet high. This means that it is even higher than Mount Everest. After this, Sisley's 'Mount Erne' number comes up. It is the world's only oldest volcano. This is 3,5000 years old. Volcano 'Stromboli' is called 'Lighthouse of Mediterranean'. The reason for this is that it keeps on making sense all the time.
Do volcanoes produce minerals?
There are many types of minerals in the lava released from the volcano. Volcanic mountains are made of many types of rocks. These include black, white, brown rocks etc. In the US, the Andes mountain range is taken as a volcanic mountain range. Many islands in Hawaii (America) are famous for their black beaded beaches. These seas are nothing but the mineral emanating from these mountains. The volcano throws the hidden minerals into the bottomless depth of the ground at once.
Volcano intensity measurement
In order to measure the intensity of volcano in 1982, the VI Index, with a scale of zero to eight, was created. There are two volcanic eruptions of zero to two. The eruption of a third-class volcano is fatal and it happens every year. The four and five volcanic eruptions break in decade or once in a century and their lava can be up to 25 kilometers high. Volcanoes with a range of six and seven have a tsunami or earthquake. There are few volcanoes in the eighth grade. The earlier explosion occurred 24,000 years ago.
Powerful Volcano - World's Most Powerful Volcano
According to scientists, the most dangerous volcano on Earth is 'Tambora'. Which exists in Indonesia. The most powerful volcano in the Indian Ocean is 'Piston de la Furness', then Earth's largest volcano 'Magna Loa' is considered. Which is in the Hawaiian Islands. Apart from these, there are hundreds of volcanoes, which are threatened when earthquake conditions are created.
