basaltic with little gas content
No, magma is just molten rock that lies under the Earth's Crust (when outside of the Crust it is lava). What you are thinking of is probably plasma, which can be formed by superheating gas.
gas gets trapped doesn't it and magma or lava gets shot out
Yes, basaltic magma typically has low gas content compared to other types of magma. This is because basaltic magma is formed at high temperatures and pressures which allows gases to escape more easily. The low gas content contributes to the relatively quiet and effusive eruptions common with basaltic magma.
An igneous rock formed from magma is intrusive.
Magma
Rhyolitic magma is typically formed from the melting of continental crust rocks such as granite and other felsic rocks. These rocks have high silica content, which contributes to the high viscosity of rhyolitic magma. Magma properties can also be influenced by other factors such as water content and temperature.
Igneous rock is formed from the solidification of magma as it cools.
Intrusive igneous rocks are formed by magma. Magma can also cause the contact metamorphism of rock that it is intruded into.
The rate of cooling of the magma determines the type of mineral formed by the magma or lava..
Minerals are formed from magma when the lava cools and hardens to produce a solid
Much of the gas that comes out of a volcano was originally trapped in the magma under pressure. When the magma encounters lower pressure the gas comes out. The process is similar to soda fizzing when the bottle is opened. some of the gas may be steam the formed from groundwater boiling from the intense heat.
