A volcano in the world, we have both a powerful Volcano (active volcanoes) is a mountain that is still there every point is. Volcano mountain is quiet (the dormant volcanoes) ever have been dashed in the past, every part of every current will not have another power outage and completely (extint volcanoes) is a volcano that has not been prathuma since in the past. Thus, the mountains may be born of the volcano is more oriented to power oriented itself when there's a volcano. Magma that is leading in the crust which comprises elements that are assembled as a fluid, or known as MAK came. Some types of element, which is a component of the magma become magma and gas with high heat, move closer to the surface of the world gas which is lighter than floating above the magma and tried to push myself through the crust out. If the crater of the volcano has been turned off, it is a lot of accumulated gas occurred at the mouth of the crater. When enough gas, it will push until closed the stones crack distributing small pieces of stone pieces became less available to be pushed up into the air with magma. After that, it will flow into the surface of the Earth. The pressure and flow of magma, or MAK, might occur in the flow, which has moved slowly, or severe eruption causes a floating stone chips and dust covered the world. The difference of the magma is pushed out in the nature of the blast or the flowing movement to this slowly. Scientists found that the composition of the magma is a key element in making the volcano blast each time there is a style of violence is different in case of the following:1.) if the magma contains a lot of iron and magnesium, it is less viscous so it flows slowly.2.) if the magma contains a lot of silica, it is very viscous, so when the eruption it burst.3) magma with gas contamination is characterised by. This is a burst of explosive violence, so when the volcano blow up something that was pushed through the floor crust comes out, it will have both the status of solid, liquid and gas. Solid range is characteristic of lava (lava flow). To spread the flow to a radius of hundreds of kilometers. The size varies from as small dust or powder is heavy multi large tons when the temperature drops, it will become a stone called volcanic (pyroclastic) precipitated the flyer into the air when they won cool down is called ash (volcanic ash), thuli volcano, etc. Liquid lava rises through the crater lava up into the atmosphere will look different in each bomb, such as the chemical composition of the different causes of every point of the volcano located at the different mentioned above. And in the shape of a volcano, and different, it has resulted directly from the physical properties and characteristics of different types of lava, gas. Caused by volcanic explosions are composed of water vapor. Carbon, chlorine and anhydrous H2S gas off site etc.
