FAQ

Those who are looking for an answer to the question «How can bowens reaction series determine the silica content in magma?» often ask the following questions:

👉 How does silica content affect magma?

  • Magmas that have a high silica content will therefore exhibit greater degrees of polymerization, and have higher viscosities, than those with low-silica contents. The amount of dissolved gases in the magma can also affect it's viscosity , but in a more ambiguous way than temperature and silica content. Click to see full answer.

👉 How does silica content affect a magma?

It gives it violent or gentle eruptions.

👉 Magma that has a high silica content?

felsic

Higher silica contents will be in the igneous rocks that form with lower temps. Ones that form earlier in the series like olivine have lower percentages of silica.

What is the relationship of magma and silica content?

The chemical composition of igneous rock and magma can be placed on a scale in which the content varies from high in silica, to total lack of silica. High silica magmas are extremely thick and viscous. Low silica magmas are thin and runny.

What type of magma has a high silica content?

Felsic

How does the silica content of magma affect the eruption?
  • The silica content of the magma determines how thick the magma is, how easily it flows and how easily dissolved gases within the magma can escape; therefore the silica content determines the characteristic of the volcanic eruption and the shape and size of the resulting volcanic cone.
What happens when the silica content of magma is high?

Nothing happens, necessarily. Felsic (high in silica) magmas do, however, tend to erupt violently when and if they reach the surface.

What igneous rock or magma has the lowest silica content?

ultramafic

Which type of magma has the highest silica content and viscosity the least silica content and viscosity?

Felsic magma has the highest silica content of all magma types, between 65-70%. As a result, felsic magma also has the highest gas content and viscosity, and lowest mean temperatures, between 650o and 800o Celsius (1202o and 1472o Fahrenheit).

The viscosity of magma depends upon its silica content and its?

temperature

What effect does silica content have on the characteristics of magma?

Silica is something in the magma, so it is a pretty important part of magma because it pretty much a part that makes magma!

What effect does silica content have on the charactersitics of magma?

The silica can make the magma flow slower and also can make the magma's color lighter.

What is it called when magma has the highest silica content?

Felsic.

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

low silica content (basaltic magma)

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

low silica content (basaltic magma)

Does magma having a silica content of 50 percent is more mafic than one having a silica content of 70 percent?

Correct. The lower the silica content, the more mafic the magma is.

What is viscosity and how is it related to silica content in magma?

Viscosity is the thickness of a liquid. Things that have high viscosity include these liquids: honey, corn syrup, and yogurt. Things that have low viscosity include these things: water, coffee, and skim milk. Silica is what makes it thick, the more silica there is, then the more viscosity it has. In magma, the more viscosity (silica) it has, the bigger the volcano erupts. If it has less silica then it just seeps out slowly. You can expierment this by heating up tomato sauce and water at the same temperature.

What is silica content?

Silica is silicon dioxide, the most common component found in rocks and minerals. The composition of different types of magmas are assessed partly based on silica content, or the amount of silica in them. This content significantly affects how the lava behaves.

How does the silica content of magma affect how explosive a volcano can be?

the silica content affects the viscosity of the magma. an acidic rock (high silica content) will produce a more runny, less viscous magma, this type of magma has the ability to flow more easily and release pressure of a long period of time (hawaii). whereas basic magmas contain more silica, this causes more viscous magma, which has the ability to build up pressure in a magma chamber until the pressure is too great and it has explosive characteristics, eg Mt St Helens. safe mate

What is the silica content of magma that would result in a pyroclastic flow?

it is normally intermediate flow because of the silica content.

What does silica content mean?

Any metrial or thing which containts silica in it is call silica content..

Why is silica content important?

Silica also is used in grinding and polishing glass and stone; in foundry molds; in the manufacture of glass, ceramics, silicon carbide, ferrosilicon, and silicones; as a refractory material; and as gemstones. Silica gel is often used as a desiccant to remove moisture.

How is the ability of the magma to flow related to its silica and water content?

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.

What are two reasons that magma with a high silica content tend to cause explosive eruptions?

Magma with a high silica content tend to cause explosive eruptions because it has a stiff consistency and blocks the vents. When magma pushes from behind it more pressure happens which means the eruption will be explosive. It also prevents gas and water vapor from getting out. The gases will expand until it explodes.

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 between silica content of magma and the explosiveness of a volcanic eruption?

The higher the silica content of the magma, the more explosive the eruption. Magma enriched in silica has a higher viscosity (resistance to flow). Pressures are more likely to build up behind the thicker, high silica content magma and result in potentially more explosive eruptions.

What is the relationship between the silica content of magma and explosiveness of a volcanic eruption?

The high the silica content, the explosive and the eruption.

volcanic cone
A spatter cone is a low, steep-sided hill or mound that consists of welded lava fragments, called spatter, which has formed around a lava fountain issuing from a central vent. Typically, spatter cones are about 3–5 meters (9.8–16.4 ft) high.
