Does silica or water have the greater effect on the eruptive force of the volcano?
Water gas a greater influence. Regardless of the amount of silica present, an eruption cannot be explosive if there is no gas present, and the chief gas is water vapor. Magma that is high in silica but low in gas content will be slowly extruded to form a lava dome or a very thick lava flow.
Why is silica rich magma associated with explosive eruptions?
Silica-rich magma has high viscosity, which can trap gas bubbles. When pressure builds up, the gas can cause explosive eruptions as it tries to escape through the thick magma. The high silica content also promotes the formation of explosive pyroclastic materials during an eruption.
Why is magma that contains little silica less likely to erupt explosively?
Magma with low silica content is less viscous, allowing gas bubbles to escape more easily, reducing pressure buildup that leads to explosive eruptions. In contrast, high-silica magma is more viscous, trapping gas bubbles, which can lead to explosive eruptions when pressure is released suddenly.
Is petrol a solid gas or liquid?
The word "fume" generally implies a gas. The only common exception I know of is in the two word phrase "silica fume", which is sometimes used for very fine solid silica particles that have been prepared by a process including a step of passing silica through a fume stage. Such solid material is preferably called "fumed silica".
What are 3 substances that affect the explosiveness of volcanic eruptions?
Water, gas content, and silica content are three substances that can affect the explosiveness of volcanic eruptions. Higher water content can generate more explosive eruptions, whereas higher gas content and higher silica content can also contribute to increased explosiveness.

What two properties of magma determine what kind of volcano will form?
The silica content and the gas content of magma are two properties that determine what kind of volcano will form. Magma with low silica content and low gas content tends to form effusive, shield volcanoes, while magma with high silica content and high gas content tends to form explosive, stratovolcanoes.
Is silica a type of gas in a volcano?
No. Silica, or silicon dioxide, is a component of magma and most rocks on earth. It is a solid under most conditions but will form part of the liquid melt of magma. Pure silica in mineral form is called quartz.

What are some characteristics of the magma of a shield volcano?
Magma needs a some sort of level of silica and gas.

What do both silica and water do to magma?
Silica is silicon dioxide. Is is perhaps the most common compound on earth. In magma the amount of silica is key in determining the viscosity. More silica leads to a more viscous magma.
