Which factors determine the violence of a volcanic eruption?
Hear this out loudPauseAlthough there are several factors triggering a volcanic eruption, three predominate: the buoyancy of the magma, the pressure from the exsolved gases in the magma and the injection of a new batch of magma into an already filled magma chamber.
What are the two factors that determine if a volcanic eruption will be quiet or violent?
Hear this out loudPauseThe amount of water vapor and other gases present is one factor that determines whether a volcanic eruption will be quiet or explosive.
What are the 2 main things that come out of a volcano when it erupts?
Hear this out loudPauseThe main component of volcanic gas emissions is water vapour, followed by carbon dioxide (CO2), sulphur dioxide (SO2), and hydrogen sulphide (H2S). Volcanoes release gases when erupt, and through openings called fumaroles (Figure 11.7). They can also release gas into soil and groundwater.
What are three factors determine the nature of a volcanic eruption?
What Three Factors Determine the Nature of a Volcanic Eruption? What Three Factors Determine the Nature of a Volcanic Eruption? The nature of a volcanic eruption is determined by the temperature, viscosity and the amount of dissolved gases in the magma, according to San Diego State University.
How does the eruption of a volcano benefit mankind?
Over geologic time, volcanic eruptions and related processes have directly and indirectly benefited mankind: Volcanic materials ultimately break down and weather to form some of the most fertile soils on Earth, cultivation of which has produced abundant food and fostered civilizations. The internal heat associated with young volcanic systems has…
How does the viscosity of lava affect the shape of a volcano?
Viscosity also affects the shapes of lava flows and the mountains they erupt from. The more viscous the magma, the fatter the lava flow. Also, the more viscous the magmas a volcano erupts, the steeper the volcano.
Can a volcano eruption at one volcano trigger an eruption at another?
There is no definitive evidence that an eruption at one volcano can trigger an eruption at a volcano that’s hundreds of kilometers/miles away or on a different continent.
