Which property of magma will change the viscosity?
Silica content determines viscosity. The higher the silica content the more viscous (slower moving). Ultramafic <45% silica Least viscous Mafic 45-52% Silica Intermediate 53-65% Silica Felsic >65% Silica Highly viscous
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.
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.
A magmas viscosity is directly related to its?
A magma's viscosity is directly related to its temperature and silica content. Higher temperatures and lower silica content result in lower viscosity, making the magma more fluid and able to flow more easily.
What is a magmas viscosity related to?
The silica content. A higher silica content results in a more viscous magma.
Does the increase in silica increase the viscosity of a magma?
it is normally intermediate flow because of the silica content.
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)
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 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.
Which property of magma will change the viscosity?
Silica content determines viscosity. The higher the silica content the more viscous (slower moving). Ultramafic <45% silica Least viscous Mafic 45-52% Silica Intermediate 53-65% Silica Felsic >65% Silica Highly viscous
What mineral determines magma viscosity?
A magma's viscosity is directly related to its degree of silica content.
Magma viscosity is directly related to what?
silica content

What is relationship between silica content and viscosity?
magma that has more silica is more viscous
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.
