Does low silica magma cause explosive volcanic eruptions?
Not usually. Explosive eruptions are more often to magma with high or moderate silica levels.
What element has the greatest effect on magma characteristics?
The silica content in magma has the greatest effect on its characteristics. High silica content makes magma more viscous and results in explosive volcanic eruptions, while low silica content produces runny magma and less explosive eruptions.
What type of eruption is it when it has silica?
Eruptions characterized by high silica content are typically explosive and are known as silicic or rhyolitic eruptions. The high viscosity of silica-rich magma traps gases, leading to increased pressure and violent eruptions. This type of eruption can produce pyroclastic flows, ash clouds, and volcanic domes, contrasting with the more effusive eruptions associated with low-silica basaltic magma.
What type of magma that tends to cause explosive eruptions has a what?
Magma that tends to cause explosive eruptions is typically high in silica content, making it thick and viscous. This results in gas build-up and pressure within the magma chamber, leading to explosive eruptions.
Highly explosive volcanoes tend to have what type of magma?
Highly explosive volcanoes typically have magma that is high in silica content, which leads to increased viscosity. This viscous magma traps gas bubbles, creating significant pressure buildup within the volcano. When the pressure is released, it results in explosive eruptions. The most common types of magma associated with such eruptions are rhyolitic and andesitic magmas.
Does low silica magma cause explosive volcanic eruptions?

What is Krakatoa a silica rich or a silica poor?
Krakatoa is silica-rich, meaning it contains a high amount of silicon dioxide (silica) in its composition. This high silica content is associated with explosive volcanic eruptions due to the interaction between silica and magma.
Is mount Popocatepetl high in Silica?
Yes, Mount Popocatepetl is high in silica because it is a stratovolcano, which typically contains high amounts of silica in its magma composition. Silica-rich magma tends to be more viscous, leading to explosive eruptions as seen with the eruptions of Popocatepetl.
Compare and contrast the three types of magma?
Basaltic Magma is typically forms when rocks in the upper mantle melt...Andesitic Magma is found along continental margins....Rhyolitic Magma forms when molten material rises and mixes with the overlying silica-and water-richcontinental crust...All 3 of them is a magma.
Plinian eruptions are the most powerful type of eruption They are usually caused by what kind of magma?
Plinian eruptions are caused by highly viscous magma with high eruptive column heights, explosive fragmentation of magma, and high gas content, often derived from silica-rich (silicic) magma. This type of magma tends to trap gases leading to highly explosive eruptions characteristic of Plinian events.
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.
What type of magma will produce explosive eruptions?
Magma with high silica content (felsic magma) tends to produce explosive eruptions because it is more viscous and traps gases, leading to pressure build-up before they are released explosively. This type of magma commonly forms in subduction zones where oceanic plates are being subducted beneath continental plates.
