mostly water vapor,and some carbon dioxide.minor Sulfur,Chlorine, and Fluorine gases
There are many different types of ET volcanoes, so there are many different answers for this question. There are even ones that spew out methane ice!
Gases
yes and no. water effects the magma. a lot of water will make magma harden faster. but a little water makes the magma speed up/move faster. magma gases don't really effect water, its really the volcanic ash and toxic fumes that effect the water. (volcanic mudslides also effect water)
No. Granite forms from magma, which is liquid rock. There are gasses trapped in the magma, but they only make up a small portion of it.
basaltic magma ,Andesitic magma and Rhyolitic magma
Changes in magma
· It is determined by the primary factors of the magma's Temperature, its Composition, and the amount of Dissolved Gases it contains.

gases
Yes, gases do come out and then the magma under the Earth's crust.
The gasses bubble out of the magma, sometimes explosively.
The more gases, water vapor and silica there is in magma the bigger the explosiveness of a volcanic eruption.
The main cause of an explosive volcano is the amount of gases trapped in the magma. If the gases have had time to escape, there will be less pressure built up resulting in a less vicious magma explosion.
yes
There are hot gases mixed with magma. Sometimes the pressure of the magma and hot gases increased a great deal when this happens the rocks deep inside the earth have melted on molten rocks which is called magma. This is how a magma occurs.
yes, but it depends on what type of magmaIt is TRUE. So yes, dissolved gasses comprise up to a few percent by weight of a magma. Hope this helps! have a nice day =]
Magma with less silica is thinner and runnier.Therfore, gases can move out of the magma easily.
