Why is magma that contains little silica less likely to erupt explosively?

Magma with less silica is thinner and runnier.Therfore, gases can move out of the magma easily.

Why is magma that contains little silica less to erupt explosively?

What determines if a volcano erupts quietly or explosively?
silica levels
Where do mafic and felsic magma originate?
Felsic is a term that means that a rock contains types of silica. Fesic magma is magma that is high in silica particles and low in iron particles.
What is the behavior of lava with silica content being high and low?
Lava with high silica content will erupt explosively, if it has low silica content it will flow.
What is an eruption called when the magma is thin runny and contains very little silica?
a viscous eruption

How does the quartz in the lava effect it and how it erupts?
If lava contains quartz that means the silica content is high. A high silica content makes lava more viscous, and gives it the tendency to erupt explosively.

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.
What causes the difference between quiet and exploses eruptions?
It depends on how much silica is in the magma. If there is low-silica in the magma then the volcano will erupt quietly. If there is high-silica in the magma then the volcano will erupt explosively.

What is a mineral that effects the thickness of magama?
The more silica in lava, the more viscous the lava is. Silica (SiO2) content varies from 50 percent to 70 percent. Basaltic lava, which is 50 percent silica, is runny and contains relatively little gas. Granitic lava, typically around 70 percent silica, is 70 percent silica. It is much thicker and contains much more gas. As a result when granitic lava flows, it tends to release gasses (water and carbon dioxide) explosively. The lava on the Hawaiian Islands in basaltic, and flows easily. The lava in Mount St Helens is very thick, so when it finally reaches the surface it causes a much more violent and dangerous eruption.
Which layer of the earth contains the most silica?
Soil contains most of the silica. It is very useful for man.
Is river sand silica?
Sand usually contains abundant silica, but it generally is not pure silica.
