What type of magma do highly explosive volcanoes have?
Highly explosive volcanoes typically have viscous, silica-rich magma known as rhyolitic magma. This type of magma contains high amounts of gas and is prone to causing explosive eruptions due to the trapped pressure within the magma chamber.
Which set of magma conditions produces the most explosive eruptions?
Magma that is high in silica content and gas bubbles is most likely to produce the most explosive eruptions. This type of magma creates high viscosity, which traps gas bubbles and builds up pressure until it violently explodes. These eruptions typically occur at stratovolcanoes like Mount St. Helens.
How hot does magma have to be to explode?
The explosive potential of magma depends more on viscosity gas content than on temperature. Most magmas are at temperature of at least 700 degrees Celcius. Interestingly, the most explosive magmas are the high-silica magmas, which have lower melting temperatures.
Does a composite volcano have silica?
Yes it is high in silica because composite volcanoes are known for being explosive. Composite volcanoes, sometimes referred to as stratovolcanoes, one of Earth's most common type.They form by explosive eruptions of pyroclastic material followed by quieter outpourings of lava. This usually indicates high silica content. High silica makes for thicker magma that can clog up the vent from the volcanoe's last eruption. Which makes the next eruption far more explosive because the magma has to free its self out of the vent, and with tremendous force it succeeds sky rocketing billions of pieces of pyroclastic material out of its vent. (this is known as an explosive eruption.)
What can cause the most explosive volcano?
If you get a very sticky magma (molten rock) which can occur due to the composition of the magma it makes it hard for gas to escape (e.g. think of blowing bubbles through honey and water, its harder through honey), when the gas does escape out of these sticky magma's it has built up a lot of pressure and explodes.

Does water vapor affect how explosive a volcano is?
Yes. More gas trapped in magma leads to a more explosive eruption. Water vapor is the most abundant gas in magma.

What type of magma will produce explosive eruptions?
Magma with high silica content (felsic magma) tends to produce explosive eruptions because it is more viscous and traps gases, leading to pressure build-up before they are released explosively. This type of magma commonly forms in subduction zones where oceanic plates are being subducted beneath continental plates.
What is the melted material beneath the Earth's surface?
This material is most often referred to as magma.
If basalt is in lava is the volcano explosive?
Basaltic lava tends to be less explosive than other types of lava because it has lower viscosity and gas content. However, the explosiveness of a volcano is influenced by multiple factors including the volcano's history, magma composition, and gas content. While basaltic lava eruptions are typically less explosive, there can be exceptions.
