What are the two factors control the explosiveness of a volcano?
The viscosity of the magma and its gas content.
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 factors control the explosiveness of an eruption?
The explosiveness of an eruption is primarily controlled by the viscosity of the magma and the amount of gas trapped in it. Low viscosity magma with high gas content tends to lead to more explosive eruptions, while high viscosity magma with lower gas content leads to less explosive eruptions.
Does Andesitic magma have both an intermediate gas content and explosiveness?
Andesitic magma typically has an intermediate gas content, resulting in eruptions that can be explosive, but not as violently explosive as magmas with higher gas contents like rhyolitic magma. The explosiveness of Andesitic magma eruptions can be influenced by factors such as the speed of gas release and the presence of water or other volatiles.

What are the 3 types of magma?
basaltic magma ,Andesitic magma and Rhyolitic magma
Do intermediate contains the least amount of silica?
No, intermediate magma typically contains a moderate amount of silica compared to other magma types. Basaltic magma has the lowest silica content, while rhyolitic magma has the highest silica content.
What is the relationship between the silica contents of magma and the explosiveness of a volcanic eruption?
The high the silica content, the explosive and the eruption.
Is andiestic magma high in silica?
Yes, andesitic magma is intermediate in silica content, typically ranging between 57-63% silica. This silica content contributes to its intermediate viscosity and eruptive behavior, which often results in explosive eruptions.
How does the high water content affect the explosiveness of volcanoes?
High water content can increase the explosiveness of volcanoes because it promotes the formation of steam and gas bubbles in magma, building up pressure that can lead to explosive eruptions. When water interacts with magma, it can cause rapid expansion and fragmentation of the magma, creating explosive eruptions with ash clouds and pyroclastic flows.
What is the silica content of magma that would result in pyroclastic flow?
it is normally intermediate flow because of the silica content.
