What else can I help you with?
What happens if there is a lot of water present in the magma of a volcano?
The large amount of water would first increase the amount of magma, as it make it easier to melt rocks. Then the water vapor would help cause explosive eruptions.
How could water help a volcano?
It is unclear what it means to "help" a volcano, but water does tend to make eruptions more explosive.
What kind of vapor is in a volcano?
Often there is water vapor if it's a dormant volcano, and/or sulphurous fumes and hot gasses.. plus toxic farts...
Why do you think water vapor erupt from a volcano instead of liquid water?
A volcano vents water vapor instead of liquid water because that water has been in contact with very hot rocks, well above the boiling point of water. Some of the water vapor comes from the molten magma itself.
What is an oceanic volcano?
An oceanic volcano is a volcano located on the ocean floor, often forming underwater mountains or seamounts. These volcanoes can be explosive or non-explosive and contribute to the formation of oceanic islands or mid-ocean ridges.
What is trapped in magma that can cause explosive eruptions?
Gas, primarily water vapor.
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 material do explosive volcanoes produce?
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.
What is the specific water vapor and silica conditions that cause differences in eruptions?
Water vapor can make a volcano explode into millions of pieces. Therefore the silica will put it back together, with gravity on its' side. Then lava will concave and erupt therefore making everything in its path rubble.
What two factors control whether an eruption will be explosive or quiet?
Water vapor and silica
If a volcano contained magma with small proportions of water and silica would you predict a nonexplosive eruption or an explosive one why?
This would result in a non-explosive, "runny" eruption, similar to what you get in Hawaii, where the volcano simply pours out lava. Explosive reactions occur when rocks contain large amounts of water and silica, which flash into steam, resulting in a rapid expansion, and thus a dangerously explosive reaction.
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.
