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 %).


What does viscosity have to do with eruptions?

The viscosity of magma or lava will determine whether or not the eruption is explosive or quiet. Higher viscosity magma can result in explosive eruptions. Lower viscosity magmas tend to flow more freely.


Why do volcanic eruptions differ?

The main cause of differences in volcanic eruption characteristics is due to the viscosity of the magma. High viscosity magmas are high in sticky silica which traps gas and produces explosive eruptions. Low viscosity magmas are low in silica and produce eruptions with far less energetic characteristics.


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.


How are the eruptive styles different depending on the magmas viscosity?

depending on the space before and temp at the time
