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 %).

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 element has the greatest effect on magma characteristics?
The percentage of silicon in magma greatly affects its viscosity.
Where does the viscosity of magma depends?
1. Chemical Composition of the magma. 2. Concentration of the melt. 3. Presence of Volatiles. 4. Amount of Water present in the magma.
What factors determine the force of a volcano eruption?
Factors that determine the force of an eruption are magma viscosity and gas content.
What is a magmas viscosity related to?
The silica content. A higher silica content results in a more viscous magma.
What is the relationship between silicon content and the viscosity of magma?

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 is the silica content of magma that has low viscosity?
low silica content (basaltic magma)
What is silica content of magma that has a low viscosity?
low silica content (basaltic magma)
What conditions make for a violent volcanic eruption?
Magma with high silica content
What element has the greatest effect on magma characteristics?
The percentage of silicon in magma greatly affects its viscosity.
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.
Magma viscosity is directly related to what?
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 properties of magma help determine the type of eruption?
The properties of magma that help to determine the type of eruption are the magma's viscosity and its silica content. Those volcanoes that exhibit massive eruptions have a high viscosity and high silica content.
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.
