What affects the speed of lava flows?
The temperature and the silica content will both affect the viscosity of lave which will in turn affect the flow rate (whereby the lower the temperature and the higher the silica content, the higher the viscosity and the lower the flow rate).
What is the silica content of magma that would result in pyroclastic flow?
it is normally intermediate flow because of the silica content.
What is the behavior of lava with silica content being high and low?
Lava with high silica content will erupt explosively, if it has low silica content it will flow.
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.
Why does more silica make lava flow slow?
In rocks lava with a high silica content the silica starts to form a covalent network, where the silicate groups continously bond together.
What kind of eruptions and speed of flow do high silica and low silica magmas have when they erupt as lava?
For eruptions it is explosive and for speed of flow it is 6 miles per hour. When the eruption as lava is 18 miles per hour.

How does silica content affect igenous rocks?
It determines high silica or low silica. It will determine if it is sticky or not, or if it flows fast or slow. *high in silica~Sticky, and slow. Will not flow easily. *low in silica~Fact, not sticky. Will flow easily.
How does lava that contains a greater amount of silica flow?
Lava that contains a greater amount of silica will flow slower and more sluggishly. The silica affects the viscosity of the lava making it thicker and therefore moving at a slower pace.
Blood capillaries have fast or slow flow?
Capillaries have slow flow. This slow speed maximizes opportunities of diffusion of oxygen, nutrients, and wastes.
Does the increase in silica increase the viscosity of a magma?
it is normally intermediate flow because of the silica content.
What is the behavior of lava with silica content being high and low?
Lava with high silica content will erupt explosively, if it has low silica content it will flow.

What effect does silica content have on the charactersitics of magma?
The silica can make the magma flow slower and also can make the magma's color lighter.
Why does more silica make lava flow slow?
In rocks lava with a high silica content the silica starts to form a covalent network, where the silicate groups continously bond together.
