No, Magma is a combination of molten rock and iron, that originates from the earth's mantle.
Felsic magma
The three types of magma, named for the rock they form are basaltic, rhyolitic and andesitic. Rhyolitic magma is rich in silica and water vapor.
Yes. More gas trapped in magma leads to a more explosive eruption. Water vapor is the most abundant gas in magma.
Rhyolitic magma typically contains a high amount of silica and water vapor. It is known for its high viscosity and tendency to produce explosive eruptions due to the buildup of gas pressure within the magma chamber.
Gas, primarily water vapor.
The large amount of water would increase the amount of magma, making it easier to melt rocks. The water vapor would help the magma cause explosive eruptions.
Magma contains a variety of gasses, the most common of which are water vapor, carbon dioxide, and sulfur dioxide.
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.
Oxygen is not a common gas in magma. Magma is typically composed of gases such as water vapor, carbon dioxide, sulfur dioxide, and hydrogen sulfide.
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.
The more gases, water vapor and silica there is in magma the bigger the explosiveness of a volcanic eruption.
When magma and water come into contact, the heat from the magma causes the water to vaporize and turn into steam. This steam can then be used to drive turbines and generate electricity through a geothermal power plant.
