Volcanos

outlets 2. There are three main factors that check out the genius of volcanic eruptions. to each one factor has defined characteristics that can determine the effects of the volcano. The factors are the magma?s composition, temperature and the amount of dissolve gases. Each of these affects the magma?s viscosity, which is directly related to the nature of the eruption. The amount of silica 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 most of amount of silica (approximately 70%) and dissolved g...If you want to get a full essay, order it on our website: Ordercustompaper.com
