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.

Does magma having a silica content of 50 percent is more mafic than one having a silica content of 70 percent?
Correct. The lower the silica content, the more mafic the magma is.
Magma can be classified according to its content.?
silica
What is a magmas viscosity related to?
The silica content. A higher silica content results in a more viscous magma.
This type of magma has low silica content?
There are three types of magma that contains silica. Basaltic Magma has 50 percent silica, Andesitic Magma has 60 percent silica, and Granitic Magma has 70 percent silica.
What is the silica content of magma that would result in pyroclastic flow?
it is normally intermediate flow because of the silica content.
What is the silica content of magma that has low viscosity?
low silica content (basaltic magma)
What is silica content of magma that has a low viscosity?
low silica content (basaltic magma)
What is a magma's viscosity directly related to?
The silica content. A higher silica content results in a more viscous magma.
Does magma having a silica content of 50 percent is more mafic than one having a silica content of 70 percent?
Correct. The lower the silica content, the more mafic the magma is.
Does the increase in silica increase the viscosity of a magma?
it is normally intermediate flow because of the silica content.
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.

Is andiestic magma high in silica?
Andesitic magma has intermediate silica content. Rhyolite has the highest(>68%) and Basaltic the least.
What effect does silica content on the characteristics of magma?
Silica is something in the magma, so it is a pretty important part of magma because it pretty much a part that makes magma!
