What is a magmas viscosity related to?
The silica content. A higher silica content results in a more viscous magma.
What is the viscosity of a dilute dispersion of silica particles in water?
Dilute? Less than .1% I would guess viscosity of Water
How does silica affect viscosity?
The higher the silica the higher the viscosity.
How does silica content and viscosity effect igneous rocks?
As silica content increases viscosity increases.
The viscosity of magma depends upon its silica content and its?
The viscosity is also dependent on temperature. Higher Temperature results in lower viscosities typically, i.e more runny.

What is a magma's viscosity directly related to?
The silica content. A higher silica content results in a more viscous magma.
How does silica affect viscosity?
The higher the silica the higher the viscosity.

The viscosity of magma depends upon its silica content and its?
The viscosity is also dependent on temperature. Higher Temperature results in lower viscosities typically, i.e more runny.
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.
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
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.
How does the silica content of lava impact its viscosity?
Silica content is directly proportional to viscosity, so the higher the silica content of a lava, the higher its viscosity. high viscosity means a lava will be thick and slow moving, hence probably meaning an explosive eruption. lava's with a high viscosity include rhyolite and andesite whereas lava's with a low viscosity (runny ones) include basalt.
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
