The two main factors are the viscosity and the gas content of the magma. explosive eruptions usually occur when magma approaches the surface and dissolved gasses bubble out so rapidly that it escapes explosively, creating clouds of ash and pumice. If there isn't enough gas this can't happen. High viscosity magma by definition does not flow easily. This allows pressure to build inside or under a volcano as the magma moves slowly. The higher viscosity also means the magma can hold more gas.

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.
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.
What factors determine the force of a volcano eruption?
Factors that determine the force of an eruption are magma viscosity and gas content.
Two factors control whether an eruption will be explosive or quiet?
The composition of the magma and the presence of trapped gases are two key factors that determine whether a volcanic eruption will be explosive or quiet. A high gas content and viscous magma can lead to explosive eruptions, while eruptions with low gas content and more fluid magma tend to be quieter.
What are the two factors that affect the explosiveness of a a volcanic eruption?
The explosiveness of a volcanic eruption is largely influenced by the magma's composition and the amount of trapped gases within it. Magma with high viscosity and gas content tends to lead to more explosive eruptions, as the gases can build up pressure within the magma chamber until they are forcefully released.

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.
How fast can an explosive eruption demolish a mountainside?
An explosive eruption can demolish a mountainside within minutes to hours, depending on factors such as the size of the eruption, type of volcanic material ejected, and the stability of the mountain. The force and speed of the explosion can rapidly disintegrate and erode the mountain's structure, causing large-scale devastation.
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).
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.
Identify and explain the 3 factors that effect the force of a volcanic eruption?
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 important factors determine whether an eruption will be explosive or quiet?
The two important factors that determine whether an eruption will be explosive or quiet are the viscosity of the magma (how thick or sticky it is) and the presence of gases dissolved in the magma (such as water vapor and carbon dioxide). High viscosity and high gas content typically lead to explosive eruptions, while low viscosity and low gas content lead to quieter eruptions.
