Water can get trapped in magma through different processes such as being included within minerals as they crystallize, being dissolved in the magma, or being released from the surrounding rocks and incorporated into the magma. As the magma rises towards the surface, the pressure decreases, causing the water to separate from the magma and form bubbles, which can contribute to explosive volcanic eruptions.
It stays in the magma chamber underground. Once it comes out, it is lava.

What happens when water trapped underground comes into contact with hot magma?
The water will flash to steam, resulting in what is known as a phreatic eruption.
How does the release of trapped gases in magma cause a volcano to erupt?
When magma rises towards the surface, the pressure decreases. This drop in pressure causes the dissolved gases, such as water vapor and carbon dioxide, to exsolve from the magma as bubbles. As the magma continues to rise, these expanding gas bubbles create pressure within the volcano that eventually leads to an explosive eruption.
What is dissolved under pressure and are trapped in magma underground Dissolved blank under pressure are trapped in magma underground?

What dissolves under pressure are trapped in magma underground?
Gases, such as water vapor and carbon dioxide, dissolve in magma when it is under pressure deep underground. As the magma rises to the surface and pressure decreases, these gases can come out of solution, leading to volcanic eruptions.
What determines whether a volcano will erupt violently or quietly?
if a volcano is high in silica, it will be explosive. If its low in silica, it will be quiet. Two important things that determine whether an eruption will be explosive or quiet: # The amount of water vapor and other gases that are trapped in the magma. # If the magma is basaltic or grantic.
What is trapped in magma that can cause explosive eruptions?
Gas, primarily water vapor.
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.
How does the presence of water in magma increase the chance of an explosive eruption?
At the temperatures found in magma water would normally be a gas, but is trapped under pressure as long as the magma is underground. When pressure is reduced enough the water vapor can bubble out of the magma very rapidly, resulting in an explosion.

Where was the gas before it shot out of the volcano?
The gas was trapped in the magma.
What dissolves under pressure are trapped in magma underground?
Gases, such as water vapor and carbon dioxide, dissolve in magma when it is under pressure deep underground. As the magma rises to the surface and pressure decreases, these gases can come out of solution, leading to volcanic eruptions.
Do the gases trapped in the magma cause the magma to erupt to the surface?
No, the fact that the magma has such a low density is why it rises. However, gasses do effect the manner in which it erupts.
What determines whether a volcano will erupt violently or quietly?
if a volcano is high in silica, it will be explosive. If its low in silica, it will be quiet. Two important things that determine whether an eruption will be explosive or quiet: # The amount of water vapor and other gases that are trapped in the magma. # If the magma is basaltic or grantic.
Is granite made by magma that was trapped in the earth's crust?
Yes. Granite forms when silica-rich magma cools underground.
How does the air get caught in a volcano?
When magma rises through the conduit of a volcano, dissolved gases in the magma are released as pressure decreases. As the magma nears the surface, the decreasing pressure causes the gases to form bubbles, which can get trapped within the magma. When the volcano erupts, these trapped gases are released explosively, propelling ash, gas, and lava into the air.
