Higly explosive volcanoes tend to have what type of magma?
Highly explosive volcanoes tend to have thick and viscous magma with high silica content. This type of magma traps gases, leading to pressure buildup and explosive eruptions. Examples of explosive volcanoes include stratovolcanoes like Mount St. Helens.
What type of magma do high explosive volcanoes have?
Viscous, gaseous magma, usually of high acidity as compared to basalt.
Volcanoes typically have the most explosive eruptions?
Large explosive eruptions are generally characteristic of stratovolcanoes.
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.
Why are some volcanoes more destructive then others?
Well, all volcanoes create land, but explosive volcanoes also destroy land. Explosive volcanoes are explosive because they have a lot of gas and pressure inside them, and then the pressure suddenly drops. That's when the volcano starts erupting.

What type of magma does a composite volcano have?
Composite volcanoes typically have andesitic magma, which is intermediate in composition between felsic and mafic magmas. This type of magma is more viscous than mafic magma, leading to explosive eruptions and the buildup of lava and ash layers that form the characteristic steep-sided cone shape of composite volcanoes.
Plinian eruptions are the most powerful type of eruption They are usually caused by what kind of magma?
Plinian eruptions are caused by highly viscous magma with high eruptive column heights, explosive fragmentation of magma, and high gas content, often derived from silica-rich (silicic) magma. This type of magma tends to trap gases leading to highly explosive eruptions characteristic of Plinian events.
What type of magma is found on composite volcano?
The average composition of magma in a composite volcano is andesitic. Composite volcanoes are highly variable though. They can erupt anything from basalt to rhyolite.
Which type of volcano has explosive eruptions due to thick magma which contains a large amount pf pressurized gas?
A stratovolcano, also known as a composite volcano, is the type of volcano that has explosive eruptions due to thick magma containing a large amount of pressurized gas. The build-up of pressure from the trapped gas within the viscous magma leads to explosive eruptions that can be highly destructive.
What type of volcano has magma that contains large volumes of gases but not silica and water?
A volcano with magma that contains large volumes of gases but not silica and water is typically a shield volcano. These volcanoes have low viscosity magma that allows gases to escape easily, resulting in relatively gentle eruptions characterized by lava flows.
What type of volcanic rock do you find in a explosive volcano?
Explosive volcanoes can produce pumice and tuff.
Are volcanoes that always erupt explosively located on water or land?
Volcanoes that always erupt explosively can be located on both water and land. The type of eruption is determined by the composition of the magma within the volcano, not its location. Explosive eruptions are typically caused by the high pressure buildup of gas within the magma.
