Yes. The gas is actually the primary driving force behind explosive eruptions.
What else can I help you with?
Can Gas trapped in magma under high pressure can cause explosive eruptions.?
Yes. The gas is actually the primary driving force behind explosive eruptions.
Gases that are trapped build up pressure in magma and can cause what?
The build-up of pressure from trapped gases in magma can cause explosive volcanic eruptions. The sudden release of this pressure propels magma, ash, and gases violently out of the volcano, leading to potentially devastating and widespread destruction.
What type of magma that tends to cause explosive eruptions has a what?
Magma that tends to cause explosive eruptions is typically high in silica content, making it thick and viscous. This results in gas build-up and pressure within the magma chamber, leading to explosive eruptions.
Why can lava be explosive or non explosive?
Lava can be explosive if it is high in gas content, such as dissolved water vapor or carbon dioxide, which can cause pressure to build up and lead to explosive eruptions. On the other hand, lava can be non-explosive if it is low in gas content and flows more easily without building up pressure, resulting in effusive eruptions with slower lava flows.
Does low silica magma cause explosive volcanic eruptions?
Not usually. Explosive eruptions are more often to magma with high or moderate silica levels.
Can Gas trapped in magma under high pressure can cause explosive eruptions.?
Yes. The gas is actually the primary driving force behind explosive eruptions.
What is trapped in magma that can cause explosive eruptions?
Gas, primarily water vapor.
Gases that are trapped build up pressure in magma and can cause what?

What type of magma that tends to cause explosive eruptions has a what?
Magma that tends to cause explosive eruptions is typically high in silica content, making it thick and viscous. This results in gas build-up and pressure within the magma chamber, leading to explosive eruptions.
Does thin magma cause explosive eruptions?
No, quiet eruptions.
Why can lava be explosive or non explosive?
Lava can be explosive if it is high in gas content, such as dissolved water vapor or carbon dioxide, which can cause pressure to build up and lead to explosive eruptions. On the other hand, lava can be non-explosive if it is low in gas content and flows more easily without building up pressure, resulting in effusive eruptions with slower lava flows.
What type of eruptions cause a cinder cone?
Explosive
Do both quiet and explosive eruptions cause craters?
YES
Do silica-rich magma cause explosive eruptions?
yes
Does low silica magma cause explosive volcanic eruptions?
Not usually. Explosive eruptions are more often to magma with high or moderate silica levels.
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.
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.
