Question

Quizplus · Accepted Answer

All of the factors mentioned (composition of the magma, temperature of the magma, and amount of dissolved gas in the magma) play a role in determining the nature of a volcanic eruption. The composition of the magma affects its viscosity, which in turn affects how easily gases can escape from it. Higher temperatures generally lead to more fluid magma, which tends to produce less violent eruptions. Additionally, the amount of gas dissolved in the magma can build up pressure until it is eventually released explosively, leading to a more violent eruption. Therefore, all of these factors must be taken into account to predict the nature of a volcanic eruption.
