Volcanos

come to the forelets 2. There are terce main factors that check out the genius of volcanic eruptions. to each one factor has specify characteristics that can determine the effects of the volcano. The factors are the magma?s composition, temperature and the measuring stick of dissolve gases. Each of these affects the magma?s viscosity, which is directly related to the nature of the eruption. The fall of silicon dioxide content is directly related to the viscosity, as well. The composition of Mafic magma is virtually 50% silica, which makes it the least viscous of the three composition types. It as well as contains the least amount of dissolved gas (1-2%).

This type of volcano is found on the island of Kilauea, in Hawaii. Intermediate or Andesitic magma contains nigh 60% silica and 3-4% of dissolved gas. This type of volcano shapes a composite cone, such as Mt. Rainier in Washington. The third form of magma composition is Felsic. It contains the close to of amount of silica (approximately 70%) and dissolved g...If you want to nail a full essay, order it on our website: OrderCustomPaper.com
