What is a magma's viscosity directly related to?
The silica content. A higher silica content results in a more viscous magma.
What is the difference in silica content and viscosity between light color and dark colored magma?
The lower the viscosity is the hotter the magma is and faster it flows.Higher the viscosity is the cooler it is and slower it flows down.
What mineral determines magma viscosity?
A magma's viscosity is directly related to its degree of silica content.
What is Mt Fuji's magmas viscosity?
It is quite viscous with a high silica content.
What conditions make for a violent volcanic eruption?
Magma with high silica content
What is relationship between silica content and viscosity?
magma that has more silica is more viscous
What is the relationship between silicon content and the viscosity of magma?
Although other factors such as temperature and water content also affect the viscosity of magma, silica-rich magmas tend to be more viscous than silica-poor magmas in similar situations.
How does silica content and viscosity effect igneous rocks?
As silica content increases viscosity increases.
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 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
What is a magmas viscosity related to?
The silica content. A higher silica content results in a more viscous magma.
Magma viscosity is directly related to what?
silica content
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 a magma's viscosity directly related to?
The silica content. A higher silica content results in a more viscous magma.
What is the relationship with silica viscosity and lava flow?
An increase in the silica content of a lava increases it's viscosity. Viscosity can be thought of as a fluids resistance during deformation to shear or tensile stress, or in more simple terms, how easy or difficult it is to make a fluid flow. As viscosity increases, a fluid will flow less easily, so a lava with a high silica content will be more viscous and will flow less easily / more slowly than a low silica lava.
