Because if the water content of magma is high, anexplosive eruption is more likely. Because magma is underground, it is under intense pressure and water stays dissolved in the magma. If the magma quickly moves to the surface, the pressure suddenly decreases and the water and other compounds become gas. As the gases expand rapidly, an explosion occurs.

What factors determine the force of a volcano eruption?
Factors that determine the force of an eruption are magma viscosity and gas content.
Which factors determine how violent an eruption will be?
· It is determined by the primary factors of the magma's Temperature, its Composition, and the amount of Dissolved Gases it contains.
Identify and explain the 3 factors that effect the force of a volcanic eruption?
The silica content effects the force of a volcanic eruption because magma with a lot of silica is thicker and magma with less silica is thinner. The amount of dissolved gases in magma effects the force of a volcanic eruption because the less gas in the magma, the less pressure will be inside the volcano. The temperature of the magma effects the force of a volcanic eruption because the hotter the magma, the more runny it is.
What combinations is most likely to result in a violent volcanic eruption?
The most likely combination to result in a violent volcanic eruption is the presence of highly viscous magma (such as rhyolitic or andesitic magma) and a large amount of dissolved gas (particularly water vapor and carbon dioxide). These conditions can lead to a buildup of pressure within the magma chamber, causing a violent and explosive eruption. Other factors such as the presence of a vent or conduit for the magma to reach the surface and the structural weakness or faults in the volcano can also contribute to the severity of the eruption.
How forceful an eruption is depends on the composition of the?
magma within the volcano. Magma with high gas content and high viscosity tends to create more explosive eruptions, while magma with lower gas content and lower viscosity leads to less forceful eruptions. Additionally, the presence of water can also influence the explosiveness of an eruption.
How can the composition of magma affect the way volcano erupts?
If the composition of the magma is high in silica, the eruption will be explosive. The Eruption of Mt. St. Helens was an explosive eruption. If the composition of the magma is low in silica, it will produce a quiet eruption. The eruption(s) of Mt. Kilauea are quiet eruptions.
What factors determine the force of a volcano eruption?
Factors that determine the force of an eruption are magma viscosity and gas content.
Which factors determine how violent an eruption will be?
· It is determined by the primary factors of the magma's Temperature, its Composition, and the amount of Dissolved Gases it contains.
What are the two important factors that affect the explosiveness of a volcanic eruption?
Pressure and magma

What about magma affects how explosive an eruption will be?
The composition of the magma affects how explosive a volcanic eruption will be.
How forceful an eruption is depends on the composition of the?
magma within the volcano. Magma with high gas content and high viscosity tends to create more explosive eruptions, while magma with lower gas content and lower viscosity leads to less forceful eruptions. Additionally, the presence of water can also influence the explosiveness of an eruption.
What conditions make for a violent volcanic eruption?
Magma with high silica content
How is strength of a volcano eruption related to the magma in the volcano?
If the magma is more viscous, the eruption is stronger.
What are three factors that affect the violence of a volcanic eruption?
Three factors that affect the violence of a volcanic eruption are the composition of the magma (viscosity and gas content), the location of the eruption (proximity to populated areas), and the type of volcano (shield, cinder cone, stratovolcano).
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
