What does viscosity have to do with eruptions?
The viscosity of magma or lava will determine whether or not the eruption is explosive or quiet. Higher viscosity magma can result in explosive eruptions. Lower viscosity magmas tend to flow more freely.
What do quiet lava eruptions generally result from?
Volcanic eruptions are always caused by magma. This applies if the eruption is quiet or explosive, or whether the magma is felsic or mafic.
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.
What type of magma will produce explosive eruptions?
Felsic magmas that are high in silica content and are highly viscous produce explosive eruptions.
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.
How do differences in magma affect volcanic eruptions?
If the magma has a high water content, then the volcano will most likely have an explosive eruption. Also, vocanoes can have explosive eruptions if the magma contains a large percentage of silica. Hope this helps!
