GEOLOGY

Detailed explanation-1: -The amount of dissolved gas in the magma provides the driving force for explosive eruptions. The viscosity of the magma, however, is also an important factor in determining whether an eruption will be explosive or nonexplosive.

Detailed explanation-2: -The two main factors that influence how a volcano will erupt are viscosity and gas content. Both are related to the composition of the magma. Hawaiian volcanoes tend to erupt basalt, which is low in viscosity and low in gas content (about 0.5 weight percent).

Detailed explanation-3: -The style of eruption depends on a number of factors, including the magma chemistry and content, temperature, viscosity, volume and how much water and gas is in it, the presence of groundwater, and the plumbing of the volcano. gases and lava.

Detailed explanation-4: -A more viscous (thick) magma will produce a more violent eruption This is controlled in part by the concentration of silica in the magma.

Detailed explanation-5: -The properties of magma determine how a volcano erupts. Whether an eruption is quiet or explosive depends on the magma’s silica content and whether the magma is thin and runny or thick and sticky.
