An explosive eruption is caused by magma with a high content of water and silica. Non-explosive eruptions are caused by either lava because it is a thicker consistency, or magma with a low content of water and silica.

∙ 12y agoAn explosive eruption includes Aa lava, the volcano has a thick cap which traps all the gasses, this builds pressure. The lava is high in Silica and has lots of water vapor.
A non explosive volcano includes, Pahoehoe lava, has a thin cap which lets pressure go easier, and is low in Silica and water vapor.

What type of volcanic rock do you find in a explosive volcano?
Explosive volcanoes can produce pumice and tuff.
Volcanoes typically have the most explosive eruptions?
Large explosive eruptions are generally characteristic of stratovolcanoes.
What type of material is produced by explosive eruptions?
bubbles
Does a composite volcano erupt quietly or explosively?
A composite volcano is the most explosive type of volcano there is. Mt. St. Helens and Mt.Vesuvious in Pompeii are both examples of composite volcanoes, and look at the damage they did. a composite volcano usually has pyroclastic flows to accompany the traditional lava and ash.
Is a shield volcano non explosive or explosive?
Shield volcanoes are generally not explosive. However, soemtimes a type of explosive event called a phreatic eruption can occur if the magma comes in contact with water.

What is acomposite volcano?
are also known as Strato volcanoes. They are the most common type of volcano, and are formed by explosive eruptions of pyroclastic material followed by a quiet outpouring of lava.

What type of eruption does MtFuji produce?
It is a composite volcano, so the kind of eruptions it has is explosive.
How does the type of volcano composite cone rupture?
Answer by FutureLPGAgolferComposite Cone - Alternation between quiet and explosive volcanoes.
What determines the strength of a volcanic eruption?
The explosiveness of a volcano is determined by two factors. The obstacles in the magma's path and the type of volcano. When there is chunks of rock and hardened magma in the vent the liquid magma builds up until it sprays out at hufe ferocity. If there is little or no debris then the magma simply spews out. As for the type of volcano when the tectonic plates move apart it forms a row of GENTLE volcanoes but when they crash together the volcanoes are much more explosive.
What type of magma do highly explosive volcanoes have?
Many have rhyolitic magma, which is high in silica. Magma with higher viscosity and higher gas content is the most explosive when released.
Is mount Krakatoa a shield volcano?
No. Caldera and shield volcanoes are quite different. Shield volcanoes usually undergo effusive eruptions, the least violent type and produce basaltic lava. Caldera forming volcanoes erupt explosively and are the most violent. They generally produce rhyolitic lava.
What type of magma do high explosive volcanoes have?
Viscous, gaseous magma, usually of high acidity as compared to basalt.
