What is the viscosity of a dilute dispersion of silica particles in water?
Dilute? Less than .1% I would guess viscosity of Water
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.
Correct order of decreasing magma viscosity?
The amount of viscosity present in magma depends on the amount of silica it has. A composite volcano produces rhyolitic lava which is very thick. A shield volcano produces a basaltic lava with less silica and significantly less viscosity.
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.
How does silica affect a volcano eruption?
The higher the silica content of the magma, the more viscous the magma. The higher the viscosity of the magma, the more explosive the eruptions of the volcano tend to be. Lower silica content lavas tend to form shield volcanoes (such as the type formed on Hawaii) where the lava can flow very long distances as it has a much lower viscosity.

Viscosity less than honey?
If something has a greater viscosity, it becomes more 'runny' compared to its original state when heated up. The greater the change from thick to runny = the greater the viscosity. So honey has a greater viscosity than water for example.
What is the comparison operator used for not equal to in Excel?
You can use the Not function or the <> operator, which is the < and the > beside each other. To see if the values in A1 and A2 are not equal to each other, you can type: =A1<>A2 or =Not(A1=A2) In each case they will either give you TRUE if they are not equal or FALSE if they are equal, in the cell that you enter the formula into.
Why do volcanic eruptions differ?
The main cause of differences in volcanic eruption characteristics is due to the viscosity of the magma. High viscosity magmas are high in sticky silica which traps gas and produces explosive eruptions. Low viscosity magmas are low in silica and produce eruptions with far less energetic characteristics.

What are the types of proportion?
Less than Less than or equal to Equal to Greater than Greater than or equal to
Greater than less than equal show the symbols?
> greater than < less than = equal to
What is the opposite of less than equal sign?
The opposite of less than or equal to is greater than or equal.And also:The opposite of greater than or equal to is less than or equal.
WHAT SYMBOL is which greater than or less than?
> is greater than; with a line under it it is greater than or equal to < is less than; with a line under it it is less than or equal to
What factors control the viscosity of magma and lava?
The three factors that control the viscosity of lava are temperature, composition and dissolved gases. When the temperature is hotter, there will be less viscous. When the composition has a higher silica content, there will be higher viscosity and a lower silica content means a lower viscosity. The gases will expand within the lava as it nears the surface of the Earth because of decreasing pressure.
