What does not affect the viscosity of magma amount of gases silica content temperature all of these affect the viscosity of a magma?
All of these factors affect the viscosity of magma. The amount of gases can influence the fluidity, while the silica content directly impacts thickness, and temperature affects the overall mobility of the magma. Therefore, none of these factors can be excluded as they all play a role in determining 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.
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
The viscosity of magma depends upon its silica content and its?
temperature. Magma with higher silica content tends to have higher viscosity, while temperature can also affect viscosity by influencing the mobility of the magma's mineral components.
Does an increase in silica increase the viscosity of magma?
Yes. Viscosity is the resistance of a fluid to flowing. A high viscosity means low flowing (I specifically mention this because this is a huge pitfall) When silica content increases, and when temperature decreases, the viscosity of a magma increases along with it.
What factors affect magma's viscosity?
The two main factors that affect viscosity are temperature and silica content. Higher temperatures lower viscosity while higher silica content increases viscosity.
What two main factors affect magmas viscosity?
The main factors that affect magma's viscosity are temperature and silica content. Higher temperatures generally result in lower viscosity, as the magma becomes more fluid. Lower silica content also leads to lower viscosity, as silica molecules tend to create more resistance to flow.

What 3 factors determine magma viscosity?
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.

What is the relationship between silica content and viscosity?
Silica content in a material directly affects its viscosity. Higher silica content leads to higher viscosity due to the formation of stronger bonds between silica molecules, which hinders flow and increases resistance to deformation. Low silica content results in lower viscosity as there are fewer bonds and the material flows more easily.
Does an increase in silica increase the viscosity of magma?
Yes. Viscosity is the resistance of a fluid to flowing. A high viscosity means low flowing (I specifically mention this because this is a huge pitfall) When silica content increases, and when temperature decreases, the viscosity of a magma increases along with it.
Does less silica equal greater viscosity?
No, generally speaking, more silica leads to greater viscosity in materials such as liquids or glasses. Silica acts as a network former in these materials and helps to increase their structural integrity, resulting in higher viscosity.
How does the silica content of lava impact its viscosity?
Silica content is directly proportional to viscosity, so the higher the silica content of a lava, the higher its viscosity. high viscosity means a lava will be thick and slow moving, hence probably meaning an explosive eruption. lava's with a high viscosity include rhyolite and andesite whereas lava's with a low viscosity (runny ones) include basalt.
What is silica content of magma that has a low viscosity?
low silica content (basaltic magma)
