Mt. Etna is a stratovolcano like Krakatoa and Mt. Vesuvius, therefore it has a high silica content. Though lava with a high silica content does not tend to travel very far away from the source; it can be a double edged sword as magma with a high silica content tends to trap gasses until it reaches a bursting point, ending in a massive eruption.
What else can I help you with?
Does magma having a silica content of 50 percent is more mafic than one having a silica content of 70 percent?
No, magma with a silica content of 50 percent is more felsic, while magma with a silica content of 70 percent is more mafic. Silica content is inversely proportional to magma's mafic or felsic classification.
Do intermediate contains the least amount of silica?
No, intermediate magma typically contains a moderate amount of silica compared to other magma types. Basaltic magma has the lowest silica content, while rhyolitic magma has the highest silica content.
How is it possible for magma to have a higher silica content than the rock from which it was formed?
Magma could have higher silica content than its parent rock, if during melting or movement it is gets in contact with silicic country rocks and absorbs them. This is reffered to as Assimillation.
Magma can be classified according to its content.?
silica
Is andiestic magma high in silica?
Yes, andesitic magma is intermediate in silica content, typically ranging between 57-63% silica. This silica content contributes to its intermediate viscosity and eruptive behavior, which often results in explosive eruptions.
What is silica content of magma that has a low viscosity?
low silica content (basaltic magma)
What is the silica content of magma that has low viscosity?
low silica content (basaltic magma)

No, intermediate magma typically contains a moderate amount of silica compared to other magma types. Basaltic magma has the lowest silica content, while rhyolitic magma has the highest silica content.
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.
What is a magma's viscosity directly related to?
A magma's viscosity is directly related to its temperature and silica content. Higher temperature and lower silica content typically result in lower viscosity, making the magma more fluid and runny. Conversely, lower temperature and higher silica content lead to higher viscosity, resulting in a thicker, more sticky magma.
Does the increase in silica increase the viscosity of a magma?
it is normally intermediate flow because of the silica content.
How is it possible for magma to have a higher silica content than the rock from which it was formed?
Magma could have higher silica content than its parent rock, if during melting or movement it is gets in contact with silicic country rocks and absorbs them. This is reffered to as Assimillation.
What effect does silica content have on the charactersitics of magma?
The silica can make the magma flow slower and also can make the magma's color lighter.

What is a magmas viscosity related to?
The silica content. A higher silica content results in a more viscous magma.
