The silica content effects the force of a volcanic eruption because magma with a lot of silica is thicker and magma with less silica is thinner. The amount of dissolved gases in magma effects the force of a volcanic eruption because the less gas in the magma, the less pressure will be inside the volcano. The temperature of the magma effects the force of a volcanic eruption because the hotter the magma, the more runny it is.

What two principal factors determine the nature or explosive potential of a volcanic eruption?
The two principal factors that can determine the nature or explosiveness of a volcanic eruption is Temperature and Composition in terms of its water content, mineralogy and volatility.
What factors determine the force of a volcano eruption?
Factors that determine the force of an eruption are magma viscosity and gas content.
What does the VEI stand for?
The VEI stands for Volcanic Explosivity Index, which is a scale used to measure the explosiveness of volcanic eruptions based on factors like volume of erupted material, height of eruption column, and duration of the eruption.
What is mount Pinatubos vei?
Mount Pinatubo's eruption in 1991 had a Volcanic Explosivity Index (VEI) of 6. This scale measures the magnitude of volcanic eruptions based on factors like volume of erupted material, height of eruption column, and duration of eruption. A VEI 6 is classified as a "colossal" eruption.
Is VEI on its own a gpod indicator of the dangers involved with a volcanic eruption?
The Volcanic Explosivity Index (VEI) provides a useful measure of the explosiveness of a volcanic eruption, categorizing eruptions based on the volume of erupted material and the height of the eruption column. However, it is not a comprehensive indicator of the dangers involved, as it does not account for other critical factors such as the eruption's location, type of volcanic activity, population density nearby, and prevailing wind patterns. Therefore, while VEI can indicate potential severity, a holistic assessment of volcanic hazards requires considering multiple factors beyond just the VEI rating.
What are three factors that affect the violence of a volcanic eruption?
Three factors that affect the violence of a volcanic eruption are the composition of the magma (viscosity and gas content), the location of the eruption (proximity to populated areas), and the type of volcano (shield, cinder cone, stratovolcano).
What two principal factors determine the nature or explosive potential of a volcanic eruption?
The two principal factors that can determine the nature or explosiveness of a volcanic eruption is Temperature and Composition in terms of its water content, mineralogy and volatility.
What are the two important factors that affect the explosiveness of a volcanic eruption?
Pressure and magma
What are the factors affecting volcanic eruption?
How full the magma chamber is and the amount of gas that is in the volcano.

When a volcano starts erupting how long will it erupt for?
The duration of a volcanic eruption can vary widely depending on the volcano and the type of eruption. Eruptions can last for days, weeks, months, or even years in some cases. It is difficult to predict the exact length of an eruption as it depends on various factors such as the magma composition, eruption style, and volcanic activity.
What factors help determine whether a volcanic eruption will be violent or quiet?
· It is determined by the primary factors of the magma's Temperature, its Composition, and the amount of Dissolved Gases it contains.
What does vei represent?
VEI stands for Volcanic Explosivity Index, which is a scale used to measure the explosiveness of volcanic eruptions based on factors such as eruption cloud height, volume of material expelled, and duration of the eruption. It ranges from 0 (non-explosive) to 8 (mega-colossal).
Factors helps determine whether a volcanic eruption will be violent or relatively quiet?
· It is determined by the primary factors of the magma's Temperature, its Composition, and the amount of Dissolved Gases it contains.
Which factors help determine whether a volcanic eruption will be explosive or relatively quiet?
The volatile content of the magma. Weather water or Ice has ingres to the volcanic vent. The physical stability of the volcano.
