What melts to form rhyolitic magma?
Rhyolitic magma is a gas. The rhyolitic magma usually has to largest gas contents.
What kind of magma produce violent volcanoes eruptions?
Rhyolitic magma. This type of magma is found where the gases can't escape like in volcanic eruptions. Because the gas can not escape, the magma becomes viscous, resulting in the explosions being violent and unpredictable. The other type of magma is Basaltic magma. This can be found where continent plates are pulling away from each other and the magma is nearer the surface. This allows the gas to escape and therefore the magma is less viscous and doesn't result in explosive volcanoes, here eruptions are gentle and 'rifts' are more likely, where lava is persistent. I hope this helps! :)
How is gas stored in a volcano?
Gas is stored in the Magma chamber at the bottom of the volcano, along with the 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.
Is magma made of 50-70 percent oxygen?
It could be, but magma differs depending on its gas percentage. The lower gas percentage it has, the smoother the magma flows. if it has a high gas percentage, it is usually explosive.
What is magma composition?
Magma is a mixture of several substances. It generally includes molten and/or semi-molten rock, volatiles such as dissolved gas or gas bubbles, and solids such as suspended. crystals. It is found beneath the surface of the earth.
Where was the gas before it shot out of the volcano?
The gas was trapped in the magma.
What gas is formed in magma?
steam
Which of these is not a common gas in magma?
Methane
What type of magma is found on continents?
I think it is the continental magma.
What Gas Content does a Shield Volcano have?
Magma in a shield volcano usually has a low gas content.
How does gas affect a volcano eruption?
Volcanoes vary a lot in how they erupt. The most important factor is the gas content of the magma. All magmas have gases dissolved in them, in the same way that soft drinks have carbon dioxide dissolved in to make them fizzy. As the magma gets close to the surface, the pressure on the magma decreases. That causes some of the gas to bubble out of the magma. Magma with low gas content comes out of the volcano without violent explosions and then flows peacefully down the sides of the volcano.
