Magma is a hot fluid from deep within the Earth's crust. The set of magma conditions that produce the most explosive eruptions are high viscosity and the presence of dissolved gases.

An explosive eruption occurs if magma is?
Eruptions are explosive if the magma is viscous and has a high gas content.
Does low silica magma cause explosive volcanic eruptions?
Not usually. Explosive eruptions are more often to magma with high or moderate silica levels.
Why is silica rich magma associated with explosive eruptions?
silica rich magma associated with explosive eruptions because it tends to trap water and gas bubbles :)
Why is Kilauea volcano non explosive?
Kilauea is a shield volcano fed by gas-poor basaltic magma. It is the gas in the magma that makes eruptions explosive. Kilauea has occasionally produced explosive eruptions when magma cam in contact with water.
Why are eruptions of mafic magma rather quiet?
The explosive force of violent eruptions is driven by gas trapped in the magma under pressure. Mafic magma often has a relatively low gas content and so usually erupts in a non-explosive or mildly explosive.
What kind of of volcanic eruption occurs when basaltic magma is present?
Basaltic magma usually produces a Hawaiian or Stombolian style of eruption.
Does thin magma cause explosive eruptions?
No, quiet eruptions.
An explosive eruption occurs if magma is?
Eruptions are explosive if the magma is viscous and has a high gas content.
Does mafic magma explode?
Mafic magma can be involced in both explosive and non-explosive eruptions.
Does low silica magma cause explosive volcanic eruptions?
Not usually. Explosive eruptions are more often to magma with high or moderate silica levels.
Why is silica rich magma associated with explosive eruptions?
silica rich magma associated with explosive eruptions because it tends to trap water and gas bubbles :)
Why is Kilauea volcano non explosive?
Kilauea is a shield volcano fed by gas-poor basaltic magma. It is the gas in the magma that makes eruptions explosive. Kilauea has occasionally produced explosive eruptions when magma cam in contact with water.
Why do the volcanoes in Japan have explosive eruptions?
Volcanoes in Japan have explosive eruptions because there is a a magma chamber that has not completely move along the mantle yet so when it erupts it has explosive eruptions.
Why does granitic magma cause explosive eruptions?
Granitic magma is highly viscous (resists flow). This high viscosity results in the entrapment and buildup of gases which create explosive eruptions.
Do silica-rich magma cause explosive eruptions?
yes
Why are eruptions of mafic magma rather quiet?
The explosive force of violent eruptions is driven by gas trapped in the magma under pressure. Mafic magma often has a relatively low gas content and so usually erupts in a non-explosive or mildly explosive.
Is magma a explosive eruption and why?
Magma is not an eruption. Magma is a mixture of molten minerals and dissolved gas that is underground. All volcanic eruptions, apart from phreatic eruptions, involve magma.
