What are the three factors that influence the explosive nature of volcanic eruption?
following are the three factors affecting volcanic eruption or volcanic activity
1. temperature rise in interior which will cause rocks to melt
2. reduction in pressure which has already increased the melting temperature of rocks.
3. addition of fluids like water which helps in decreasing melting temperature of rocks

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.
How do bicarbonates influence biotic factors?
They buffer cells from extremes of pH
What are two of the four factors that can influence the rate of a reaction?
The concentration of the substances that react is one. The temperature is another.
The non living factors that influence an ecosystem?
they are abiotic factors, and they include temperature, water, air, soil, rocks and minerals, weather, etc.... the living organisms are biotic factors which includes, pretty much anything that is living.
Which factors affect water potential in living cells?
Some factors which influence water potential include gravity, pressure, and solute concentration. Adding solute lowers the water potential. An increase of pressure will increase the water potential.
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 does the VEI stand for?
The VEI stands for Volcanic Explosivity Index, which is a scale used to measure the explosiveness of volcanic eruptions based on factors like volume of erupted material, height of eruption column, and duration of the eruption.
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.
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 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 does vei represent?
VEI stands for Volcanic Explosivity Index, which is a scale used to measure the explosiveness of volcanic eruptions based on factors such as eruption cloud height, volume of material expelled, and duration of the eruption. It ranges from 0 (non-explosive) to 8 (mega-colossal).
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.
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.
The height of a volcano determines its explosive power?
While height can influence the explosivity of a volcano to some extent, it is not the sole determining factor. The composition of magma, the presence of gas and water, and the type of eruption (effusive vs explosive) also play crucial roles in determining a volcano's explosive power. Additionally, factors such as viscosity of magma and volatility of gases can further impact volcanic explosivity.
What factor determaine the type of volcanic eruption?
The type of volcanic eruption is primarily determined by the composition of the magma beneath the volcano. Magma high in silica tends to be more viscous and leads to explosive eruptions, while lower silica magma tends to flow more easily, resulting in effusive eruptions. Other factors such as the presence of gas, the amount of pressure, and the shape of the volcano can also influence the type of eruption.
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).
