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.
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.
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.
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 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 factors determine how explosive the eruption of a volcano will be?
In a volcano, the higher the pressure rises before eruption takes place, the more explosive the eruption will be. Some volcanoes seem to be "gentle flow" as a matter of course (like Mauna Loa in Hawaii). Some seem to be explosive as a matter of course (like Vesuvius in Italy). Others manifest both types of eruptions.
