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.
What factors determine if a volcanic eruption will be quite or explosive?
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 are the two factors control the explosiveness of a volcano?
The viscosity of the magma and its gas content.
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.
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 two things cause the viscosity of magma?
Silica and pressure
What 3 factors determine magma viscosity?
The three elements that determine viscosity in magma are:TemperatureSilicaOxides (gases)Viscosity changes the way in which magma will flow. Magma with low viscosity will flow much more easily than high viscosity magma.

What factors affect magma's viscosity?
The two main factors that affect viscosity are temperature and silica content. Higher temperatures lower viscosity while higher silica content increases viscosity.
WHAT ARE THE THREE TYPES OF MAGMA AND THE DIFFERENCES?
The three types of magma are basaltic, andesitic, and rhyolitic. They differ in their silica content, viscosity, and eruptive behavior. Basaltic magma has low silica content, low viscosity, and tends to erupt quietly, while rhyolitic magma has high silica content, high viscosity, and tends to erupt explosively. Andesitic magma falls in between these two in terms of composition and behavior.

What two main factors affect magmas viscosity?
The main factors that affect magma's viscosity are temperature and silica content. Higher temperatures generally result in lower viscosity, as the magma becomes more fluid. Lower silica content also leads to lower viscosity, as silica molecules tend to create more resistance to flow.

What two things does the appearance of a volcano depend on?
One factor that influences a volcanic eruption is the composition of the lava; the thicker the lava, the more explosive the eruption. Another factor is the level of pressure that forces magma up a pipe or vent; the higher the pressure, the more violent the eruption.
What controls the violence of a eruption?
Two things need to be consider here;Location that is how close is the magma chamber and the surfaceDisturbances beneath the earth(stress of the convection current)which can determine the pressure exerted below the earth,do influence or control the violence of volcanoes
