What else can I help you with?
Which flows easier high silica magna or low silica magna?
Low silica magma typically flows easier than high silica magma because low silica magma has lower viscosity, meaning it is less resistant to flow. High silica magma is more viscous due to the presence of more silica tetrahedra in its composition, making it thicker and more difficult to flow.
What does high level of silica cause magma to become?
High levels of silica cause magma to be more viscous
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.
Do gases escape from a low silica magma easier than it does a high silica magma?
yes
What mineral that affects magma thickness?
The mineral that affects magma thickness is silica. Magma with high silica content tends to be more viscous, resulting in thicker magma. Conversely, magma with low silica content is less viscous and flows more easily.
Does the increase in silica increase the viscosity of a magma?
it is normally intermediate flow because of the silica content.
Magma that is high in silica and produces explosive eruptions?
Magma that is high in silica tends to be more viscous and traps gas bubbles, leading to explosive eruptions. The high silica content increases the magma's explosivity and can result in ash clouds and pyroclastic flows during eruptions. These types of eruptions are characteristic of stratovolcanoes, such as Mount St. Helens.
Is the following sentence true or false high - silica magma has high viscosity?
True. High-silica magma, such as that found in rhyolitic compositions, has a high viscosity due to the increased bonding between silica molecules. This results in a thicker, more resistant flow compared to low-silica magma, which is more fluid and has lower viscosity.
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 low-silica magma?
A magma containing not much silica (= SiO2). For example: a basaltic magma. These magma's have a low viscosity since the lower the SiO2-content, the lower the viscosity; and hence flow easily (↔ a felsic magma).
What type of magma has a high silica content?
rhyolitic magma has a lot of silica and water vapors... thanks for asking answers.com ;)
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.
