What else can I help you with?
Does the increase in silica increase the viscosity of a magma?
it is normally intermediate flow because of the silica content.
What type of magma has a high silica content?
rhyolitic magma has a lot of silica and water vapors... thanks for asking answers.com ;)
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.
What does low silica magma form?
Nealy all magma on Earth is originally low-silica, mafic magma. Most magma originates from the upper mantle, which is ultramafic, meaning it has a very low silica content. This rock may partially melt under certain conditions, forming mafic magma, which has a somewhat higher silica content than the mantle rock.
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 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)
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.
Do gases escape from a low silica magma easier than it does a high silica magma?
yes
What does all the silica in basaltic magma or lava combine with as it cools?
Oxygen.
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.
