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.
A page flow is a directory of web application files which work together to implement a user interface feature.

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.

They don't have one. They go with the flow.
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.
If the basalt flow contains air bubbles and pockets and there is a spring that contains silica then the silica can deposit into the air bubbles (the air bubbles are known as Amygdaloidal basalt or vesicles) If the silica deposits slowly and the conditions are correct then precious opal can form. Two examples of this would be in California at the Nowak and the Barnett mines.
it is normally intermediate flow because of the silica content.
it is normally intermediate flow because of the silica content.
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.
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.
it is normally intermediate flow because of the silica content.
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.
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.
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.
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.
The silica can make the magma flow slower and also can make the magma's color lighter.
