An explosive eruption occurs if magma is?
Eruptions are explosive if the magma is viscous and has a high gas content.
What content in magma causes an explosive eruption?
Water and silicates are common components of the viscous lava that can expand explosively in an eruption.
What type of magma do high explosive volcanoes have?
Viscous, gaseous magma, usually of high acidity as compared to basalt.
Does Hawaii experience effusive or explosive eruptions?
Occasionally, yes. Most of Kilauea's eruptions are effusive, however.
What are tha things you do after and before during the volcanic eruption?
you are asking a seemingly simple question but it has a complex answer. Prior to an eruption you have the forming of the caldera. Then you have the eruption: here are some effusive eruption, central vent eruption,fissure eruption, subaqueous eruption, sub glacial eruption, pyroclastic eruption, ash-flow eruption. The most spectacular of all of them is the pyroclastic eruption. It throws off viscous gas-rich magmas and producesw a great deal of solid volcanic fragments. A volcanic eruption after is called clean up. The included link about Mt St Helens eruption will give you an idea on the potentially explosive power of a volcano.

Will an explosive eruption have more gas and be more dense than an explosive flow or would it be less gaseous and less viscous?
if the volume is bigger than the other gass and the gass is flamable methan, yes it will be more dence than the other when explodes or is ignited, the reason is that the gas will have less time to spread.

How does magma composition and the resulting eruption affect the form of a volcano?
If the composition of the magma is high in silica, the eruption will be explosive. The Eruption of Mt. St. Helens was an explosive eruption. If the composition of the magma is low in silica, it will produce a quiet eruption. The eruption(s) of Mt. Kilauea are quiet eruptions.
What type of lava does an explosive eruption produce?
An explosive eruption typically produces thick and sticky lava known as silica-rich or felsic lava. This type of lava has high viscosity and trapped gas bubbles, causing it to erupt violently. As the lava is very viscous, it can block and build pressure in the volcano, resulting in explosive eruptions.
What kind of eruption form composite cone volcano?
Composite volcanoes are highly variable in what they erupt. Most often, eruptions will release clouds of ash, pumice, and rock fragments. In some cases they fountain or extrude lava.
Why have the eruptions from Eyjafjallajokull been so explosive?
There are two reasons for it being so explosive:1) Magma was trapped in a magma chamber close to the surface where it became more viscous, this meant less gas was able to escape prior to the eruption so the eruption was more explosive.2) Because there is ice on top of the volcano there were explosions when the ice heated up very quickly due to expanding water vapour.
How is strength of a volcano eruption related to the magma in the volcano?
If the magma is more viscous, the eruption is stronger.
What is an eruption called when the magma is thin runny and contains very little silica?
a viscous eruption
