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.
What else can I help you with?
What are the two factors control the explosiveness of a volcano?
The viscosity of the magma and its gas content.
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 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 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.
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 important factors that affect the explosiveness of a volcanic eruption?
Pressure and magma

What are two factors that can affect the distance that volcanic ash can travel?
Wind direction and speed: Strong winds can carry volcanic ash over long distances, while variable wind patterns can influence the direction in which the ash travels. Eruption intensity: The height and explosiveness of the volcanic eruption can determine how high into the atmosphere the ash plume reaches, affecting how far it can be dispersed.
What are 2 factor that determine the degree of violence with which a volcano erupts?
Two key factors that determine the degree of violence in a volcanic eruption are magma viscosity and gas content. High-viscosity magma, such as that rich in silica, tends to trap gases, leading to increased pressure and more explosive eruptions. Conversely, low-viscosity magma allows gases to escape more freely, resulting in less violent eruptions. Additionally, the amount of dissolved gases, such as water vapor and carbon dioxide, influences the eruption's explosiveness.
What are the two most important factors to control the growth of bacteria?
Temperature and hygiene.
What is the rules of factoring?
Each organism has two factors that control each of its traits. We now know that these factors are genes and that they are located on chromosomes
What effects did the Mt Krakatoa eruption have on the island?
Two thirds of the island disappeared during the eruption.
