Magma with less silica is thinner and runnier.Therfore, gases can move out of the magma easily.
What else can I help you with?
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.
Do these hot spot volanoes tend to erupt more explosively than other volcanoes?
no they do not erupt more explosively. It depends on its gas and on its viscosity. an example is Kilauea in Hawaii it does not erupt explosively.
How do cinder cone volcanos erupt?
Cinder cone volcanoes erupt explosively, but not as violently as composite volcanoes.
What is the behavior of lava with silica content being high and low?
Lava with high silica content tends to be more viscous and flow more slowly, leading to explosive eruptions. In contrast, lava with low silica content is less viscous and flows more easily, resulting in gentler, effusive eruptions.
How does magma with lots of silica trap gases?
Magma with high silica content is more viscous, which can trap gases within the molten rock. The high viscosity makes it harder for gases to escape to the surface, allowing them to build up pressure until they eventually erupt explosively.
Why is magma that contains little silica less likely erupt explosively?
Magma with less silica is thinner and runnier.Therfore, gases can move out of the magma easily.
What does the amount of silica in a volcanos magma determine about its eruption?
If a volcano's magma is high in silica, the volcano will probably erupt explosively. If the magma is not high in silica, the volcano will probably erupt quietly.
How does the quartz in the lava effect it and how it erupts?
If lava contains quartz that means the silica content is high. A high silica content makes lava more viscous, and gives it the tendency to erupt explosively.
What causes the difference between quiet and exploses eruptions?
It depends on how much silica is in the magma. If there is low-silica in the magma then the volcano will erupt quietly. If there is high-silica in the magma then the volcano will erupt explosively.
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.
Do oceanic hot-spots tend to erupt more than other volcanoes?
No they do not erupt explosively. It depends on its gas an its viscosity. Kilauea in Hawaii does not erupt explosively.
Does hot spot volcanoes tend to erupt more explosively than other volcanoes?
No they do not erupt more explosively. It depends on its gas and its viscosity. Kilauea in Hawaii does not erupt more explosive.

WHAT ARE THE THREE TYPES OF MAGMA AND THE DIFFERENCES?
The three types of magma are basaltic, andesitic, and rhyolitic. They differ in their silica content, viscosity, and eruptive behavior. Basaltic magma has low silica content, low viscosity, and tends to erupt quietly, while rhyolitic magma has high silica content, high viscosity, and tends to erupt explosively. Andesitic magma falls in between these two in terms of composition and behavior.
How does the Mauna Loa erupt?
explosively with abundant pyroclastic material
How do cinder cone volcanos erupt?
Cinder cone volcanoes erupt explosively, but not as violently as composite volcanoes.
Can a stratovolcano erupt blocky lava?
Yes. Stratovolcanoes can erupt blocky lava flows, basaltic lava flows, or may erupt explosively.
