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.

∙ 13y agoThe amount of silica effect how magma flows is very important. If a volcano has lots of silica, its eruption would be explosive and the magma would be chuncky and very sticky. It would be like peanut butter running down a plate.

Things that have low viscosity include these things: water, coffee, and skim milk. Silica is what makes it thick, the more silica there is, then the more viscosity it has. In magma, the more viscosity (silica) it has, the bigger the volcano erupts. If it has less silica then it just seeps out slowly. You can expierment this by heating up tomato sauce and water at the same temperature.

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
How does temperature affect viscosity of motor oil?
Yes. If the temperature changes enough, the viscosity of oil will change, too. Oil is designed to resist changes in viscosity with temperature changes, at least to a degree. But if the change (either hotter or colder) is extreme, then the viscocity will most certainly change. And, as you'd expect, as it gets hotter, the viscosity of oil decreases (it get thinner), and as it gets colder, the viscosity of oil increases (it gets thicker).
How do you change the viscosity of honey?
You can change the viscosity of honey by adding water. While you will no longer have pure honey, the water will change its viscosity. The viscosity of pure honey is approximately 10,000 cP at 20°C and at 1 atmosphere. However, this will vary with the type of honey you have.
What could happen to earths surface if there was a change in the water cycle?
There could be change in the content of water. It will affect the level of water in the water bodies.
How could you change the viscosity of the substances?
Cooling a fluid increases the viscosity. Otherwise, to thicken it or increase the viscosity, requires the addition of another chemical.
How does heating a liquid affect the viscosity and why?
it affects the viscosity because the liquid changes the shape and turns it to a gas and the viscosity by change the form

How would you define viscosity - index?
The viscosity index refers to the measure of the change of viscosity with a change in temperature.
What is the effect of temperature change to the amount of heat content of the substance?
The effect of temperature change to the amount of heat content of the substance is called heat transfer. As heat increases, the temperature decreases.
Is viscosity a chemical or a physical change?
viscosity is a physical characteristic not a physical change. it is the thickness of a substancephysical changes would be if it turned from solid into a liquid.for example a chocolate bar goes through a physical change when it becomes melted chocolate.

Conditons in which color and viscosity of saliva changes?
causes are change the color and viscosity saliva
How the viscosity of a liquid affect how quickly an object can move through it?
Viscosity describes a fluid's resistance to flow or change in form, essentially measuring thickness of a liquid in everyday terms. The higher the viscosity the slower an object can pass though it; likewise, the lower the viscosity the faster an object will be able to move though it.For example: You can move a spoon more easily though a bowl of water than through a bowl of honey. The water is less viscous (thinner) compared to the (thick) honey.
What could happen to earths surface if there was a change in the water cycle?
There could be change in the content of water. It will affect the level of water in the water bodies.
How does condensation affect weather?
A change in the amount of water vapor in the air affects humidity and that's how condensation affect the weather.
Predict the change in viscosity as heat is added to or removed from a sample of oil?
think of it as this viscosity is thick when it is heated what will happen
