The viscosity is also dependent on temperature. Higher Temperature results in lower viscosities typically, i.e more runny.

Where does the viscosity of magma depends?
1. Chemical Composition of the magma. 2. Concentration of the melt. 3. Presence of Volatiles. 4. Amount of Water present in the 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 is a magmas viscosity related to?
The silica content. A higher silica content results in a more viscous magma.
Does an increase in silica increase the viscosity of magma?
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.
What are 3 substances that affect the explosiveness of volcanic eruptions?
Amount of dissolved gasses in a liquid, the silica content, and the viscosity of the magma.
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.
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.
Magma viscosity is directly related to what?
silica content

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
What conditions make for a violent volcanic eruption?
Magma with high silica content
What factors affect magma's viscosity?
The two main factors that affect viscosity are temperature and silica content. Higher temperatures lower viscosity while higher silica content increases viscosity.
