of course it is it is made from the molten stuff and the molten is made up of gases
An acid magma or a granitic magma.
Thick and slow-moving magma is called "silicic magma." This type of magma is typically high in silica content, making it more viscous and less able to flow easily. It often leads to explosive volcanic eruptions due to the built-up pressure.
The three things that determine how thick or thin magma is temperature, silica content, and gas content.
The magma in a cinder cone is typically thick, meaning it has high viscosity. This is because cinder cone volcanoes are formed from highly viscous and gas-rich magma which tends to solidify quickly, leading to the formation of cinders and ash during eruptions.
Gaseous thick magma equals massive explosion.
Silica-rich magma is much more thick and viscous.
Silica in natural form can be both particles or thick on fusion as in felsic magma origin
Silica is sand dust.
Silica-rich thick magma is typically classified as either dacitic or rhyolitic magma. These magmas have higher silica content, making them more viscous and able to trap gas bubbles. They often erupt explosively due to the high pressure build-up caused by the thick magma.
Silica-rich thick magma is called rhyolite. It contains high levels of silica, making it very viscous and typically light in color. Rhyolite is associated with explosive volcanic activity due to the build-up of pressure caused by the slow movement of its thick lava.
The type of magma you are referring to is called viscous magma. It is rich in silica and other minerals, making it thick and sticky. As a result, it does not flow easily and tends to form domes or plugs when it erupts.
It is Mantle or you can say Magma.
