What does the amount of silica in a volcanos magma determine about its eruption?

If a volcano's magma is high in silica, the volcano will probably erupt explosively. If the magma is not high in silica, the volcano will probably erupt quietly.

In a strombolian eruption the percent of silica changes?
Basicaly strombolian vocanic eruption is basaltic , it have lage amount of Fe and Mg . it have no or very low amount of silica
What properties of magma help determine the type of eruption?
The properties of magma that help to determine the type of eruption are the magma's viscosity and its silica content. Those volcanoes that exhibit massive eruptions have a high viscosity and high silica content.
What kind of silica do strato volcanos have?
silica-rich magma
If you have quiet eruption what kind of silica do you have?
If you have a quiet eruption you have low silica.
What kind of eruption is produced when basaltic lava that is low in silica flows from a volcano?
quiet nonexplosive eruptionsquiet nonexplosive eruptionsquiet nonexplosive eruptions
What is the relationship between the amount of gases in magma and the explosiveness a volcanic eruption?
The more gases, water vapor and silica there is in magma the bigger the explosiveness of a volcanic eruption.
What is the relationship between the silica contents of magma and the explosiveness of a volcanic eruption?
The high the silica content, the explosive and the eruption.
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.
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 is the type of volcanic eruption that has high silica?
Crazy
How does magma composition and the resulting eruption affect the form of a volcano?
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 is an eruption called when the magma is thin runny and contains very little silica?
a viscous eruption
