The lower the viscosity is the hotter the magma is and faster it flows.Higher the viscosity is the cooler it is and slower it flows down.

What is the relationship between silica content and viscosity?
magma that has more silica is more viscous
What is the difference between felsic intermediate and mafic igneous rocks?
Silica content increases from mafic to felsic, and Mg and Fe content decreases. These differences affect things such as viscosity, density and colour. Felsic magmas are the most viscous and least dense, and felsic rocks are the lightest in colour.
What conditions make for a violent volcanic eruption?
Magma with high silica content
What mineral determines magma viscosity?
A magma's viscosity is directly related to its degree of silica content.
What is a magma's viscosity directly related to?
The silica content. A higher silica content results in a more viscous magma.
What is the difference in silica content and viscosity between light-colored and dark-colored magma?
The lower the viscosity is the hotter the magma is and faster it flows.Higher the viscosity is the cooler it is and slower it flows down.
What is the relationship in the silicon content and the viscosity of magma?
There is an inverse relationship between magma viscosity and silicon content. Lavas erupting from basaltic volcanoes (like Hawaii) have a much lower viscosity and are much hotter than those erupted by volcanoes whose magmas are rich in silicon. There may be up to 8 orders of magnitude viscosity difference between basaltic magmas (SiO2 contents or about 45 %) and rhyolitic magmas (SiO2 > 70 %).
How does silica content and viscosity effect igneous rocks?
As silica content increases viscosity increases.
What is the relationship between silica content and viscosity?
magma that has more silica is more viscous
What is relationship between silica content and viscosity?
magma that has more silica is more viscous
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.

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 the relationship between silicon content and the viscosity of magma?
Although other factors such as temperature and water content also affect the viscosity of magma, silica-rich magmas tend to be more viscous than silica-poor magmas in similar situations.
What is the difference between felsic intermediate and mafic igneous rocks?
Silica content increases from mafic to felsic, and Mg and Fe content decreases. These differences affect things such as viscosity, density and colour. Felsic magmas are the most viscous and least dense, and felsic rocks are the lightest in colour.
What is the difference between constipation and diarrhea?
The difference between diarrhea and constipation is the water content of the stools.
What is the silica content of magma that has low viscosity?
low silica content (basaltic magma)
