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.

What is a page flow?
A page flow is a directory of web application files which work together to implement a user interface feature.
Which citys does the Mississippi flow through?
6000000000000000000
What are the functions of a flow chart?
There are several different types of flow charts. The main function of a flowchart is to see the steps and process of something from the beginning to the end.
Does anyone have a flow chart for HB 1117?
No dumb-as5
What type of government did the Creek tribe have?
They don't have one. They go with the flow.
Does silica or water have the greater effect on the eruptive force of the volcano?
Water gas a greater influence. Regardless of the amount of silica present, an eruption cannot be explosive if there is no gas present, and the chief gas is water vapor. Magma that is high in silica but low in gas content will be slowly extruded to form a lava dome or a very thick lava flow.
How can a basalt flow cause opal to form?
When a basalt flow comes in contact with silica-rich waters, the silica dissolves and gets carried into pore spaces within the basalt. Over time, the silica is deposited as opal in these pore spaces, forming opal-filled cavities within the basalt flow.
What is the silica of magma that would result in a pyroclastic flow?
it is normally intermediate flow because of the silica content.
What 3 factors determine magma viscosity?
Temperature: Higher temperatures result in lower viscosity since the magma is more fluid. Composition: Silica content influences viscosity, with higher silica content leading to higher viscosity. Gas content: Higher gas content increases viscosity as gas bubbles create resistance to flow.
What is the silica content of magma that would result in pyroclastic flow?
it is normally intermediate flow because of the silica content.
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.
Does the increase in silica increase the viscosity of a magma?
it is normally intermediate flow because of the 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.
Which flows easier high silica magna or low silica magna?
Low silica magma typically flows easier than high silica magma because low silica magma has lower viscosity, meaning it is less resistant to flow. High silica magma is more viscous due to the presence of more silica tetrahedra in its composition, making it thicker and more difficult to flow.
What is the importance of a silica and oxygen in lava flow speed?
Silica and oxygen content in lava affects its viscosity, which in turn impacts flow speed. Lava with higher silica content tends to be more viscous and flows slower, while lava with lower silica content flows faster. The presence of oxygen also influences lava's ability to flow by affecting its gas content and pressure.
What is the relationship with silica viscosity and lava flow?
Silica viscosity has a direct impact on lava flow behavior. Lava with high silica content is more viscous and tends to flow slowly, leading to the formation of thicker lava flows like domes or blocky lava. In contrast, lava with low silica content is less viscous and flows more easily, resulting in thinner and faster-moving lava flows like pahoehoe.
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.
