What else can I help you with?
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 are magma and igneous rock compositions categorized?
They are classified by the amount of silica vs the amount of alkalies are in the rocks or magma.
What effects does silica content have on the characteristic 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!
How does the amount of silica content change the viscosity of magma How does this affect the flow of magma?
The amount of silica and water affect the viscosity of the magma. The more viscous the magma, the slower the flow rate and the shorter and the thicker the flows. Silica makes for a more viscous 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 ;)

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 determines the viscosity of magama?
temperature, silica content, and the amount of dissolved gases determine the viscosity of magma. For instance, if the magma is cold, has a high amount of silica and has lots of dissolved gases in it the viscosity will be very high.
What 3 factors determine magma viscosity?
The three elements that determine viscosity in magma are:TemperatureSilicaOxides (gases)Viscosity changes the way in which magma will flow. Magma with low viscosity will flow much more easily than high viscosity magma.
What do both silica and water do to magma?
Silica is silicon dioxide. Is is perhaps the most common compound on earth. In magma the amount of silica is key in determining the viscosity. More silica leads to a more viscous magma.
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.
Does basaltic magma have a lot of silica or very little?
Basaltic magma is low in silica compared to andesitic or granitic magma.
