volcanoes

Volcanoes are conical structure built by discharge of lava. The dome- shaped structures not only have increased beauty of the nature and make it look magnificent but on the other hand they are extremely dangerous as they contribute to create huge catastrophes. As an illustration, the word volcano is originated from the name Vulcan, which means the god of fire in Roman. Centuries ago people believed that the eruption of volcanoes are a supernatural for instance, in Polynesia, there is a peak called Pele’s peak where people thought that the eruption was caused whenever, Pele the god of volcanoes were angry. All the misconception was because people were living a centuries of blindness where technologies weren’t used and people believe on what they heard but today with the advance of technology and intellectualism we know that volcanic eruptions are not super natural, but are the form due to the listen Volcanic eruptions may create lanscapes such as, mountains, plateaus, plains and fertile fields, but on the other hand it may also destroy landscapes. Moreover, volcanoe is a vent which magma divulges due to the pressure on the earth’s surface. Researches have shown that on average, for every cubic kilometer of magma erupts from a volcano as a result 3 to 10 cubic kilometers of molten rock stores in a large underground pool beneath the surface, which is called magma chamber. The molten rock in chamber is suppressed with great amount of pressure, which eventually breaches the rock because it is dense that the surrounding of the rock and makes its way up to the surface of the earth. When the magma erupts from volcano then it’s called lava.

Basically, volcanoes can be found in places where the tectonic plates are diverging or converging....

...Seismometer can determine if earth quack are migrating toward the surface. Also, some people monitor volcanoes by constantly mentoring gases, which comes out of fumaroles. Additionally, some recent advance technologies can determine a n accurate topography fro the data satellite.

Despite of all the huge devastations caused by the volcanoes, it can directly or indirectly produce mineral such as, gold; is close companion with volcanoes and can be find in three environments: in greenstone belts, porphyry deposits and epithermal deposits. Nickel: deposits of Nickel sulphide are mined from greenstone belts in old volcanic terrenes and its ore is associated with ultra mafic lava called komatiite. After knowing about volcanoes, their structure, nature and formation we can say that they are simply fascinating and are one of the major geological aspects of out planet.
