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 two factors seem to be most important in the formation of an explosive eruption?
The two most important factors in the formation of an explosive eruption are the viscosity of the magma and the gas content within it. High-viscosity magma, often found in felsic compositions, traps gases more effectively, leading to increased pressure buildup. When this pressure exceeds the strength of the surrounding rock, it can result in a violent release of energy and materials, causing an explosive eruption. Additionally, the presence of volatiles, such as water vapor and carbon dioxide, significantly influences the eruption's explosiveness.
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.
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.

Water vapor and silica
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 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.
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 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 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.
Which factor does not help determine whethera volcanic eruption will be explosive or relatively quiet?
The chemical composition of the magma is a key factor that influences the explosiveness of a volcanic eruption, while the time of day does not play a role in determining eruption characteristics. Factors such as viscosity, gas content, and temperature of the magma are critical, as they affect how easily gases can escape. Therefore, the time of day is irrelevant to the nature 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.
