Yes. Viscosity is the resistance of a fluid to flowing. A high viscosity means low flowing (I specifically mention this because this is a huge pitfall)
When silica content increases, and when temperature decreases, the viscosity of a magma increases along with it.

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
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 is a magmas viscosity related to?
The silica content. A higher silica content results in a more viscous magma.
What is a low-silica magma?
A magma containing not much silica (= SiO2). For example: a basaltic magma. These magma's have a low viscosity since the lower the SiO2-content, the lower the viscosity; and hence flow easily (↔ a felsic magma).
Higly explosive volcanoes tend to have what type of magma?
Magma with high silica, high viscosity, and higher gas content.
Does the increase in silica increase the viscosity of a magma?
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 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.
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 conditions make for a violent volcanic eruption?
Magma with high silica content
What is a magma's viscosity directly related to?
The silica content. A higher silica content results in a more viscous magma.
Magma viscosity is directly related to what?
silica content
What mineral determines magma viscosity?
A magma's viscosity is directly related to its degree of silica content.
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 is the relationship between silica content and viscosity?
magma that has more silica is more viscous
What is relationship between silica content and viscosity?
magma that has more silica is more viscous
