Volcanos

come onlets 2. There are troika main factors that check out the genius of volcanic eruptions. to each one factor has define characteristics that can determine the effects of the volcano. The factors are the magma?s composition, temperature and the enumerate of dissolve gases. Each of these affects the magma?s viscosity, which is directly related to the temper of the eruption. The occur of silicon oxide 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, much(prenominal) as Mt. Rainier in Washington. The third form of magma composition is Felsic. It contains the intimately of amount of silica (approximately 70%) and dissolved g...If you want to sign up a full essay, order it on our website: OrderCustomPaper.com
