What two factors seem important in the formation of an explosive eruption?
Two critical factors in the formation of an explosive eruption are the viscosity of the magma and the gas content. High-viscosity magma traps gas, increasing pressure within the volcano until it is released explosively. Additionally, the amount of dissolved gases, such as water vapor and carbon dioxide, plays a significant role in determining the potential for explosive behavior. Together, these factors can lead to violent eruptions when the pressure exceeds the strength of the surrounding rock.
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.
Is a summit eruption like an explosive eruption?
A summit eruption can involve explosive activity, but not always. Summit eruptions can also involve effusive lava flows or steady emissions of ash and gas. The specific type of eruption depends on factors such as the magma's composition, gas content, and the volcano's plumbing system.
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.
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.

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 factors determine the force of a volcano eruption?
Factors that determine the force of an eruption are magma viscosity and gas content.
What drives an explosive eruption?
An explosive eruption is primarily driven by the accumulation of gas pressure within magma beneath the earth's surface. As magma rises, the decrease in pressure allows dissolved gases, such as water vapor and carbon dioxide, to expand rapidly, leading to an increase in volume. When the pressure exceeds the strength of the overlying rock, it results in a violent release of gas and magma, culminating in an explosive eruption. Factors such as the viscosity of the magma, the amount of gas it contains, and the geological setting also play crucial roles in determining the eruption's explosiveness.
What are the two factors the control whether a volcano eruption will be explosive or quiet?
The two main factors that control whether a volcano eruption will be explosive or quiet are the viscosity of the magma and the presence of dissolved gases. High viscosity magma (thick and sticky) and high gas content tend to result in explosive eruptions, whereas low viscosity magma (thin and runny) and low gas content lead to quiet eruptions.
What factor does not help determine whether a volcanic eruption will be explosive or relatively quiet?
The mineral composition of the magma is not a deciding factor for the explosiveness of a volcanic eruption. Instead, factors such as the viscosity of the magma, the amount of gas it contains, and the surrounding pressure play a crucial role in determining whether an eruption will be explosive or relatively quiet. Higher viscosity and gas content typically lead to more explosive eruptions, while lower viscosity allows for more fluid, less violent flows.
What two factors control the explosiveness of an eruption?
The explosiveness of an eruption is primarily controlled by the viscosity of the magma and the amount of gas trapped in it. Low viscosity magma with high gas content tends to lead to more explosive eruptions, while high viscosity magma with lower gas content leads to less explosive eruptions.
