Why is magma that contains little silica less 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 likely to erupt explosively?
Magma with low silica content is less viscous, allowing gas bubbles to escape more easily, reducing pressure buildup that leads to explosive eruptions. In contrast, high-silica magma is more viscous, trapping gas bubbles, which can lead to explosive eruptions when pressure is released suddenly.
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 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.
Magma that is low in silica has little among its particles which results in low viscosity?
Magma low in silica typically contains a higher proportion of iron and magnesium, which results in a more fluid composition. This lower silica content leads to a reduced ability to form strong chemical bonds, contributing to its lower viscosity. As a result, basaltic magma, which is low in silica, tends to flow more easily compared to more silica-rich magma, such as rhyolitic magma, which is more viscous and tends 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.
Is river sand silica?
Sand usually contains abundant silica, but it generally is not pure silica.
