What is the relationship between silicon content and the viscosity of magma?

Higher silicon content in magma leads to higher viscosity. This is because silicon tetrahedra form polymerized chains that hinder flow, making the magma more viscous. Lower silica content results in lower viscosity magma.


What is silica content of magma that has a low viscosity?

low silica content (basaltic magma)


What is the silica content of magma that has low viscosity?

low silica content (basaltic magma)


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 is a magma's viscosity directly related to?

A magma's viscosity is directly related to its temperature and silica content. Higher temperature and lower silica content typically result in lower viscosity, making the magma more fluid and runny. Conversely, lower temperature and higher silica content lead to higher viscosity, resulting in a thicker, more sticky magma.


How does silica content and viscosity effect igneous rocks?

Silica content affects the viscosity of igneous rocks because higher silica content leads to higher viscosity, making the magma more resistant to flow. Rocks with higher silica content tend to form more explosive volcanic eruptions due to the build-up of gas pressure. Lower silica content leads to lower viscosity, allowing the magma to flow more easily and potentially forming more gentle eruptions.


What is a magmas viscosity related to?

The silica content. A higher silica content results in 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


A magmas viscosity is directly related to its?

A magma's viscosity is directly related to its temperature and silica content. Higher temperatures and lower silica content result in lower viscosity, making the magma more fluid and able to flow more easily.


Magma viscosity is directly related to what?

silica content


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.
