∙ 14y agoThere 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!

When rock melts into magma it releases?
Gases
Can magma gases effect water?
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)
Does granite form from gases?
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.
What are the 3 types of magma?
basaltic magma ,Andesitic magma and Rhyolitic magma
What may be indicated by changes in the ratio of sulfur dioxide to carbon dioxide in volcanic gases?
Changes in magma
Which factors determine how violent an eruption will be?
· It is determined by the primary factors of the magma's Temperature, its Composition, and the amount of Dissolved Gases it contains.
What are in active volcanoes?
gases,pressure,magma
When rock melts into magma it releases?
Gases
What does magma release when rock melts into it?
gases
WHEN MAGMA reachesthe surfacegases out of it?
Yes, gases do come out and then the magma under the Earth's crust.
When magma reaches the surface what happens to the gases?
The gasses bubble out of the magma, sometimes explosively.
What is the relationship between the amount of gases in magma and the explosiveness a volcanic eruption?
The more gases, water vapor and silica there is in magma the bigger the explosiveness of a volcanic eruption.
What causes a magma to be less viscous?
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.
Do gases escape from a low silica magma easier than it does a high silica magma?
yes
How is volcano eruption occur?
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.
Can dissolved gases comprise up to a few percent by weight of magma?
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 =]
Why is magma that contains little silica less to erupt explosively?
Magma with less silica is thinner and runnier.Therfore, gases can move out of the magma easily.
